| Caption: Viola robusta Hbd. (Violaceae): a woody species of Hawaiian
violet restricted to the high-elevation cloud forests of Moloka'i. |
| Scientific Description/Explanation: The Hawaiian violets are monophyletic lineage of angiosperms
that have undergone a putative adaptive radiation throughout the Hawaiian Islands. Species in similar habitat types (cloud
forest, high-elevation bog, and mesic streambank) exhibit remarkable parallelisms in leaf morphology and growth form.
Viola robusta was formerly classified as a subspecies of Viola chamissoniana, a dry cliff violet restricted
to O'ahu. Recent molecular systematic investigations of the Hawaiian violet lineage suggests that Viola robusta
is not a subspecies of Viola chamissoniana. |

| Caption: Visitors to a Psiguria
ternata flower near Santa Cruz, Bolivia |
| Scientific Description/Explanation:
Psiguria is a genus of vines in the Cucurbitaceae
(cucumber family) native to the New World tropics of Central
America, South America, and the Caribbean. The plants are
monoecious (have separate male and female flowers on the same
plant). Both male and female flowers are tubular, with five
partially-fused petals – similarities that, along with
the similar shapes of the male (stamen) and female (pistil)
reproductive structures, aid in "training" the pollinating
butterflies to visit both sexes. The butterfly and bee shown
in this image are not the typical pollinators of Psiguria
flowers, so they may not actually be transferring pollen to
the female flowers but rather "robbing" the plant
of its pollen and nectar. No worries though. The plants produce
a lot more pollen than they actually need to survive; an adaptation
that evolved to protect the species from extinction despite
the occasional pollen thief. |

| Caption: Stellaria media (common chickweed) photographed in a street gutter near to Volunteer Park, Seattle, WA. |
| Scientific Description/Explanation:
Stellaria media is a member of the Caryophyllaceae family, a highly plastic dicot (with both annual and perennial forms) that has achieved a near cosmetic global distribution. With a diminutive form, the plant 'hides' from general view, appearing at fist glance as an unremarkable ground cover. Yet this plant displays a remarkable morphology in its star like flowers when viewed closely; the purple stigmatic surfaces are particularly attractive. Stellaria media is considered a weed by several authors, thus causing the idle hour thought experiment: Is this species less highly valued than a similar conspecific species because it lacks showy floral displays? |

| Scientific Description/Explanation:
Linanthus parryae, commonly known as sand blossoms or
desert snow, is a diminutive annual in the Polemoniaceae (phlox
family) native to the Mojave Desert of California. This plant
species is conspicuous in the landscape in years of ample
rain, and has two color morphs, white and blue, with the white
form being most common throughout the range of the species
(hence the common name desert snow). However, in Short Canyon,
(Kern County, California) the blue color morph predominates,
as shown in this photo. Here L. parryae is photographed
from an ant’s point of view with other desert annuals
including Camissonia campestris (Mojave suncup),
Lasthenia californica (gold fields), and Linanthus
dichotomous (evening snow) and a few individuals of the

| Caption: Water use efficiency
of 'ericoid' leaves of Erica shannonea from South
Africa's Cape. |
| Scientific Description/Explanation:
Erica shannonea Andrews is a rare species of heather
in the Ericaceae. The center of diversity for Erica
lies in the Cape region of South Africa, where more than 860
species occur. Ericae have a distinctive, 'ericoid' leaf morphology.
Their microphylls (tiny leaves) are so tightly rolled together
that they have the appearance of a conifer needle. Only a
narrow slit remains open along the mid axis of the in-rolled
leaf to enable gas exchange for photosynthesis. This 'ericoid'
leaf morphology, with specialized photosynthetic tissues (palisade
cells in the mesophyll and dome-shaped epidermal cells on
the epidermis) and various types of hairs, has an adaptive
advantage in the South African Mediterranean climate. Water
use efficiency, which is influenced by ambient temperature
and relative humidity, is maximized by reducing water loss
from evaporation. Evaporation occurs via the stomatal pores
(pictured here), which open for gas exchange and carbon gain
for photosynthesis. Water loss in this high sunlight and stress
environment is reduced by minimizing the amount of leaf surface
exposed to the drying surroundings. In addition, the 'ericoid'
leaf shape, which is approximately cylindrical and has a more
or less uniform internal anatomy, facilitates efficient radial
diffusion of CO2 much like a conifer needle. In
Erica, stomata are located on the leaf surface facing
away from the sun, which has become the "inner chamber"
of the in-rolled leaf, and are not found on the adaxial side
(leaf surface facing the stem axis). |

| Caption: Selenicereus grandiflorus
(L.) Britton & Rose (Cactaceae): A night-blooming, epiphytic
cactus. |
| Scientific Description/Explanation:
Selenicereus grandiflorus (L.) Britton & Rose
(Cactaceae) is a climbing cactus, which can grow as an epiphyte
on trees by attaching adventitious roots to its support. Cactaceae
are supported as monophyletic by morphological and molecular
characters, though relationships within the family are difficult
to resolve. Members of Selenicereus are native to
tropical America. Selene (a lunar deity in Greek mythology)
as part of the generic name conveys the ethereal white quality
of the enormous flowers (grandiflorus), which are
more than 20 cm long. The common name 'Queen-of-the-Night'
also refers to this, since dozens of flowers radiate like
tiaras in the moon light when the flowers open for one night.
The reddish coloration of the bracts stems from betalains,
which are nitrogenous pigments also found in beets and Swiss
chard. Betalains are taxonomically significant, since they
only occur in Caryophyllales (most but not all families) and
to the exclusion of anthocyanins, which also confer red, purple
or blue coloration. Curiously, several hundreds of tiny beetles
frequented the flowers pictured here, though their hefty size
and fragrance hint at nocturnal bats or moths as Selenicereus'
pollinators. |

| Caption: Iris japonica,
blooming in its bright color in the Temporate House of Missouri
Botanical Garden, St Louis, MO |
| Scientific Description/Explanation:
Species in genus Iris are famous for their amazing adaptation
to insect pollination. The style of an iris flower divides
towards the apex into three petaloid branches, sometimes with
fibrous ends, such as Iris japonica in this picture. Each
branches arranges opposite to its correspond outer perianth,
together they form an excellent platform for a flying insect.
The stigmatic outer perianth showed in the picture is a sign,
guiding insects to land on this platform to get their food.
While the insect is landing, it will firstly make contact
with the pollen-receiving stigma surface, where it will deposit
the pollens it bears. Because the inner perianthes has blocked
those sideways, only after passing the stigma, the insect
can get into the deep space of the flower, where the nectar
lies. When it comes out, the anther hidden underneath the
style is waiting for it. The insect will bear the pollens
of this flower. The lower surface of the stigma is non-receptive,
which means the flower will not get self-pollinated. In conclusion,
this special form of Iris flowers maximizes the benefits of
one single interview of an insect that is able provide - It
makes itself pollinated, distributes its own pollen, and avoids
self-pollination. |

| Caption: The long inflorescences
of this spectacular undescribed Dendrochilum tend to twist
into a helix. |
| Scientific Description/Explanation:
Occasionally, a botanist is fortunate enough to visit a truly
bizarre landscape with incredible diversity and endemism,
including many undescribed species. Mt. Hamiguitan in the
Philippines is one such place. The upper slopes of the mountain
are formed of ultramafic rock, which has a high content of
heavy metals and is toxic to most plants. The mountain is
also buffeted by high winds coming directly off the Pacific
Ocean. The factors have combined to produce a stunted heath-like
forest on the mountain's tableland. Most of the plants are
scarcely knee-high, except in sheltered stream valleys. One
exception is this new species of Dendrochilum, whose waist-high
inflorescences arch over the heath canopy. Dendrochilum
has its center of diversity in the Philippines, with at least
96 species, 94% of which are endemic. This may be the largest
and showiest species in the genus. Most species are considered
epiphytes (growing on trees) or lithophytes (growing on rocks).
Terrestrial species have not been recorded before, yet this
species occurs only as a terrestrial. The ultramafic soil
may be the cause, as I have observed two other species of
Dendrochilum growing as terrestrials on the same
soil type. This species awaits description because no one
has a permit yet to collect a type specimen. Fortunately,
Mt. Hamiguitan is a protected area, so visitors should be
able to enjoy the floral display of this "rice orchid"
for many years to come. |

| Caption: The elegant white,
blue, and violet flowers of Strongylodon cf pulcher
await pollination. |
| Scientific Description/Explanation:
The genus Strongylodon (Fabaceae) has its center
of diversity in the mountains of Luzon in the Philippines.
The most famous and widely cultivated member is S. macrobotrys,
whose luminous jade green flowers make it highly coveted by
collectors. However, S. macrobotrys is by no means
the only beautiful member of the genus. This species is probably
S. pulcher, whose specific epithet, appropriately,
means "beautiful." Despite its beauty, this species
is not in cultivation, nor does it appear to have been photographed
before. Flowering plants are difficult to photograph because
flowering usually occurs high in the tree canopy, and the
only evidence of the event is fallen flowers on the ground.
Perhaps for this same reason, the Philippine species have
been poorly documented in herbarium collections. Shing Fan
revised Strongylodon in 1991 but had almost no recent collections
or fresh material to work with, so photographs, descriptions
of living plants, and accurate distribution maps are still
lacking for most species. Strongylodon macrobotrys
is not considered to be threatened by habitat destruction
because it is widely cultivated, but the other species should
be regarded as threatened or vulnerable, especially as seed
set may be very low. Although the flowers are carefully tended
by ants, they are pollinated by sunbirds or flowerpeckers,
which are becoming increasingly rare as more forest is destroyed. |

| Caption: A senescent female
flower of Rafflesia schadenbergiana |
| Scientific Description/Explanation:
Rafflesia schadenbergiana was described from the
island of Mindanao in the Philippines by Goeppert in 1885.
The flower, reportedly the third-largest in the world, was
discovered on Mt. Apo in 1882. For more than 100 years, this
species was presumed to be extinct, though occasionally rumors
of giant buds seen on the mountains of Mindanao would circulate.
In 1994, a Belgian biologist found buds, but he did not publish
his findings until December 2006 and was not able to collect
material or photograph an open flower to verify his identification.
A few species of Rafflesia have been described from buds,
but it is difficult to compare and identify species unless
they are in full flower. Rafflesia is parasitic and
relies on its host (vines of Tetrastigma, Vitaceae)
for all its nutritional needs, and it is not possible to locate
populations unless buds or flowers are present. This photograph
is the first of Rafflesia schadenbergiana. The flower
was probably close to a week old and had almost completely
darkened from its original red and white coloration. The GPS
unit, shown for scale, measures 6.9 cm wide by 15.7 cm long.
Although some species of Rafflesia can produce flowers
on aerial portions of Tetrastigma vines, R. schadenbergiana
most likely only bears flowers from subterranean portions.
A team of researchers from the Philippine National Museum
visited this population a month later, took photographs of
freshly opened flowers, and collected a specimen which may
become the neotype of the species. Rafflesia in the
Philippines has recently received a lot of attention. In addition
to the rediscovery of R. schadenberigana, five new
species have been described in the past few years, and at
least two more are awaiting publication. After more than 100
years, a Rafflesia has been seen in Samar, at the
type locality of R. manillana. Why are so many species
being found? One possibility is that widespread forest destruction
has actually improved habitat for Tetrastigma, which
prefers somewhat open areas. However, habitat degradation
has also led to populations of Rafflesia becoming critically
imperiled. The Rafflesia schadenbergiana population
in the photograph will most likely be extinct within a few
years, as it was located only meters from a newly created
corn field. In the year since the photo was taken, the area
has been converted to a tourist resort. |

| Caption: Pleomele halapepe
St. John, a shrub-type endemic species restricted to Oahu,
Hawaii. |
Scientific Description/Explanation:
The Hawaiian Archipelago includes various endemic species
that are the result of speciation subsequent to isolation
from source populations. There are six Pleomele species
native to Hawaii Islands. Pleomele halapepe St. John
are located in Oahu. Habitats can be from plains to cliffs,
and from sunny exposed areas to shadow locations. The Hawaiian
used those Pleomele species in Hawaii for one of
five standard Hula altars to honor Laka, the deity of hula.
In Hawaiian herbal medicine, hala pepe was used to cure fever
by making into freshly liquid. Notably, hala pepe is also
famous for its particular appearance and green throughout
the year. |

| Caption: One-seeded fringed
fruits of lacepod (Thysanocarpus curvipes), a winter
annual of the semiarid western United States. |
| Scientific Description/Explanation:
Lacepod, Thysanocarpus curvipes, is a member of the
mustard family (Brassicaceae) found in semiarid, rocky habitats
from extreme southeastern British Columbia south to Baja California
and western New Mexico. T. curvipes is an annual
that flowers and sets seed quickly to exploit short periods
of moisture in the winter. The genus Thysanocarpus
is unusual among the mustards in having one-seeded, fringed
fruits that remain closed at maturity. Thysanocarpus curvipes
has a great deal of geographic variation in its fruits, particularly
in the size and ornamentation of the fringe. This has been
a major character used in taxonomy of T. curvipes
and other Thysanocarpus. For instance, plants of
T. curvipes with particularly large fringes have
been recognized as variety elegans, or even as a separate
species. Analyses based on DNA sequence data, however, suggest
that there is little or no genetic distinction associated
with variation in the fringe of fruits in T. curvipes.
Unlike Thysanocarpus, most other mustards have unfringed
fruits with many seeds in two chambers. Most mustard fruits
open--sometimes explosively--at maturity. However, although
the fruits of Thysanocarpus are unusual among members
of the mustard family, similar fruits have evolved independently
several times, for example in the genera Athysanus
and Clypeola in addition to Thysanocarpus.

speciosissimum. |
| Scientific Description/Explanation:
Polystichum is a genus of ferns found worldwide,
though most of its species are in the Neotropics. The specific
epithet of this species, P. speciosissimum, literally
means "the most beautiful," making this fern "the
most beautiful Polystichum." Like all members
of this genus it usually grows at higher elevations, and this
individual was found in the paramo atop Cerro de la Muerte
in Villa Mills, San Jose, Costa Rica. This photograph is of
the abaxial, or lower, surface of a pinna (leaf division),
which is bright green on top and covered with sori (spore-bearing
structures) and golden hairs and scales below. |

| Caption: Sporangia in the sori
of Campyloneurum, a fern. |
| Scientific Description/Explanation:
Ferns are spore-bearing vascular plants. The structures which
bear their spores are called sporangia, and they are often
found on the undersides of fern fronds. Sporangia are usually
found clustered together in large groups called sori (singular:
a sorus), which, in some species, resemble the rounded tops
of Sno-Kones. This photograph shows several sori on the underside
of a frond of Campyloneurum, a Neotropical genus
of ferns. Within the large rounded clumps, the small spherical
orange structures are the sporangia, which each contain dozens
of spores. Wrapping around each sporangium is a thick red
line of cells, called the annulus. When the spores have matured
and are ready to be dispersed, the cells of the annulus dry
up and shrink like a spring being compressed, slowly pulling
the sporangium open. Eventually the cells of the annulus reach
a tipping point in the drying process, and the spring releases.
As the annulus snaps forward, the spores are shot up and out
of the sporangium, and dispersal has begun. |
