Anthurium moonenii Croat & Conçalves
One of the rarest specimens in the Exotic Rainforest collection our specimen of Anthurium moonenii was a gift from Joep Moonen (pronounced yupe), a Dutch naturalist and rain forest explorer living in French Guiana. The aroid was exported legally with documents from French Guiana along with three other rare specimens specifically for our collection. The specimen shown at the top of this page is a juvenile.
An epiphytic Anthurium species found growing on trees, the exquisite tri-lobed Anthurium was named in honor of Joep. The species is capable of growing with only a single leaf blade as can be seen in Joep's photo below right. However, at the very top of that photo you can see a tri-lobed specimen.
Anthurium moonenii was first discovered by the rain forest expert in the north eastern portion of French Guiana. He was fortunate to locate the original specimen in 1991 and brought it to the attention of Dr. Tom Croat of the Missouri Botanical Garden in St. Louis. Dr. Croat did all the original botanical work on the species verifying it was a previously unknown and unpublished Anthurium species. When it was published Dr. Croat honored Joep by granting the Anthurium Joep's last name.
In the most recent botanical literature available you will find Anthurium moonenii is known only from the north eastern portion of French Guiana and the outlying portion of the central part of Amazonas State in Brazil south of the Rio Solimoes. Mono lobed (single lobed) specimens have been located in one particular area near the Mataroni River where other rare specimens such as non-scientifically offical Philodendron 'joepii' have been located. Enid Offolter of Natural Selections Exotics in Fort Lauderdale provided this information regarding the mono lobed form, "Tom Croat and Julius Boos saw it when they were here last and Tom had been unaware of a single lobed form (stays single lobed, even when mature). The tri lobe sometimes puts out single lobes when juvenile."
Joep provided these measurements of a specimen growing in his personal collection: "Central lobe is 65 cm long (25.5 inches) and 21.5 cm (8.5 inches) at the widest. The biggest of the two side lobes is 52 cm (20.5 inches) long and 18.5 cm (7.25 inches) at the widest point. The petiole is 58 cm (22.75 inches) long and 1 cm (3/8ths inch) in diameter."
was for some time considered to be exclusively found in
French Guiana. However, Dr. Eduardo Conçalves, Brazil's most
prominent aroid botanist, has since found Anthurium moonenii in
Amazonas State in northern Brazil.
Anthurium species are
known to be highly variable and not every leaf of every specimen
will always appear the same. This link explains in
non-technical language natural variation and
Joep indicates the plants in his personal collection grow under natural conditions with no fertilizer at all. They only receive the natural rain water of the area, but that would be substantial. Joep has the advantage of living in the rain forest! We have the specimen planted in very loose soil and keep the soil mixture damp at all times. The humidity level in the Exotic Rainforest atrium is always around 85% or higher as a result of an automatic over head misting system.
An aroid, all Anthurium species reproduce via the production an inflorescence. The stalk that supports the entire inflorescence is the peduncle and the spathe produced on the inflorescence is not a flower. 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.
