Emerald Jungle Village, French Guiana Anthurium eminens was first published to science in 1855. Based on information provided by Dutch naturalist Joep Moonen (yupe or jupe), who guides botanists and tourists into the rain forest of French Guiana, northern Brazil, and Suriname, Anthurium eminens is considered a rare species in French Guiana. Both an epiphyte (ep-a-FIT) and a hemiepiphyte (hem-a-EPA-fit), the species grows on the trunks of trees. An epiphyte is a plant that grows upon another plant as a result of a seed being deposited on the tree by a monkey, bird or other rain forest inhabitant in their droppings. A hemiepiphyte is similar but can also climb the tree as a result of a seed that has germinated in the ground. The species is normally found 3 meters (10 feet) or higher up the host tree and is a member of Anthurium section Dactylophyllium, a group with palmately compound leaf blades.
Joep has observed Anthurium
eminens in French Guiana on the Approuage River, near the
Oiapoque River, and on the French side of the Rio Matabo .
He reports Anthurium eminens grows in shade with less
than 50% sunlight. He has also observed that the species is rarely
seen producing an inflorescence.
An aroid, all
Anthurium species reproduce via the production an
inflorescence. The
stalk that supports the entire inflorescence is the peduncle. When an
Anthurium is
"in flower" the reference is to the tiny flowers
containing both male and female sexual parts that grow on the spadix at the center of the inflorescence.
Unlike plants in the genus Philodendron which contain imperfect flowers
having only a single sex Anthurium possess perfect flowers
containing both sexes. To help prevent self pollination nature has
designed the female flowers to be receptive before the male portion of
the flower
produce their pollen so in most cases an insect must bring pollen from
another plant.
The spathe of Anthurium eminens is green with a purple tinge but itself is not a "flower". The spathe is simply a modified leaf. The spadix at its center vaguely resembles an elongated pine cone. The spadix is a spike on a thickened fleshy axis which can produce tiny flowers. Once the female flowers on the spadix have been fertilized by an insect, normally a beetle, they produce berries which in Anthurium emines are purple to purple-red or sometimes a purplish violet. When "in fruit", those berries contain the seeds of the aroid. When the fruit is produced the inflorescence is known to a botanist as an infructesence. Anthurium eminens has been collected in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Suriname, Venezuela and Peru. Specimens have been observed by field botanists from from 70 meters to over 2100 meters (230 to almost 6700 feet) above sea level. Anthurium eminens is a wide spread species and although rare in French Guiana is often observed in the other portions of its natural range.
In an article on Anthurium
eminens written by Anthurium expert Neil Carroll on
the International Aroid Society: website
http://www.aroid.org/ Neil
states the word "eminens" means projecting or eminent. The
reference to Anthurium eminens is in result of the aroid's
large size. Neil also says the species is scandent. Scandent is a
botanical description meaning the species climbs as well as grows
close to its host tree.
In the field notes of
aroid botanist Dr. Thomas B. Croat Ph.D., P.A. Schulze Curator of
Botany at the Missouri Botanical Garden in St. Louis, MO, Dr. Croat
states the leaf blades of Anthurium eminens are medium to
dark green on the adaxial (upper) leaf surface and are matte to semi-glossy.
The leaves are slightly paler in color on the abaxial (underside) of the blade
and the blades are subcoriaceous. Subcoriaceous is a description of
the thickness of the leaf blade and indicates the blade is just less
than leathery to the touch. When a new leaf emerges it is
surrounded by a sheath like covering known as a cataphyll. Once the
cataphyll dries the base of its fibers remain on the Anthurium.
The petioles which support each leaf (often called stems) can be
terete to just less than terete (round to less than round) and have
also been observed to be shaped like a letter "U" when cut as a
cross section.
All aroids
including Anthurium eminens variable and do not always
appear exactly the same from specimen to specimen. This link
explains in non-technical language but greater detail natural
variation and morphogenesis (ontogeny). Morphing is commonly seen
in Aroid species.
