Sometimes spelled incorrectly as "Philodendron mayoii"

Philodendron mayoi (MAY-o-e) is a recently identified smaller bladed Philodendron species from Brazil.  Philodendron mayoi was first published in the Royal Botanic Gardens Kew Bulletin in the year 2000 by Dr. Eduardo G. Gonçalves, (gon-ZAL-vas), Brazil's best known botanical aroid scientist.

Found in the rain forests of Brazil's Distrito Federal and Distrito Goias, Philodendron mayoi is reported by Dr. Gonçalves to be both terrestrial (creeping along the ground) and hemiepiphytic.  A hemiepiphyte (hem-a-EPA-fit) is a species that can begin life either growing out of the ground and then climb a tree or root on a tree as an epiphyte and then grow roots down to the soil.  Epiphytic aroid species are placed on a tree branch in the droppings of a bird or small animal who has eaten the fruit of the Philodendron species.
With a dark green upper surface to the leaf blade, the species is deeply pinnatified (divided similar to the fronds of a palm) with 4 to 6 lobes on either side of the blade.  The leaf blades of our specimen are approximately 18cm (7 inches) long.   Dr. Gonçalves notes that only hemiepiphytic plants were found producing and inflorescence.

All Philodendron sp. are aroids.  An aroid is a plant that reproduces via the production of an inflorescence.  Most people think the spathe of the inflorescence is a "flower", it is not.  The spathe is simply a  modified leaf appearing to be a hood .  If you explore the inflorescence with a magnifying glass when it is ready to be pollinated there are very tiny flowers and that can be seen on the spadix at the inflorescence' center.  The spathe which is sometimes shaped like a hood.  Inside the spathe is the spadix which somewhat resembles an elongated pine cone.  The spadix is a spike on a thickened fleshy axis which can produce tiny flowers.  When prepared to reproduce, the spadix produces male, female and sterile flowers normally separated by a sterile zone.  The tiny male flowers produce pollen and the tiny female flowers are receptive to pollen.  However, most are cleverly divided by nature to keep the plant from being self pollinated.  Nature's preferred method is to have insects (beetles) pick up the pollen from one plant and carry it to a second plant to keep the species strong.  The spathe of Philodendron mayoi is green on the outside and white inside.  However, specimens of Philodendron mayoi that produce inflorescences are extremely uncommon according to Dr. Gonçalves' technical description.
A fast growing vine when running along the ground, in it's native Brazil Philodendron mayoi is common in ravines and along streams.  It is also found growing on limestone outcroppings.  Philodendron mayoi, Photo Copyright 2008, Steve Lucas, www.ExoticRainforest.comThe aroid has been in collections since approximately the year 2000 but many have it tagged as "P. mayoii".  P. mayoi has also appeared for sale on eBay under the spelling "mayoii" which according to the original published scientific description as well as TROPICOS (a service of the Missouri Botanical Garden) is incorrect.
Philodendron mayoi was named in honor of aroid botanist Dr. Simon Mayo who works at The Royal Botanic Gardens Kew primarily with Brazilian Philodendron species.  Simon is also one of the authors of the detailed scientific text The Genera of Araceae
We grow Philodendron mayoi in moderately bright light in a fast draining soil mixture of good potting soil, extra peat, orchid bark, and Perlite.  To display the plant best, give it something to climb.  The plant is easily reproduced from cuttings which can simply be placed in loose damp soil.  Our specimen was a gift from Florida collector Russ Hammer.
Philodendron 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 terms natural variation and morphogenesis within aroid and other species.  Click here.
