Amorphophallus paenifolius

To take the picture of this amazing flower, I used the built-it flash of my camera in front of it, and I put a wireless flash behind it to clear up the corolla (with a -0.7 IL compensation).

*************************

Amorphophallus is a large genus of some 170 tropical and subtropical tuberous herbaceous plants from the Arum family (Araceae).

These are typical lowland plants, growing in the tropical and subtropical zones of the paleotropics, from West Africa to the Pacific Islands. None of them are found in the Americas although a remarkably similar but not closely related genus, Dracontium, has evolved here. Most species are endemic. They grow preferably on disturbed grounds, such as secondary forests.

These small to massive plants grow from a subterranean tuber, Amorphophallus tubers vary greatly from species to species, from the quite uniformally globose tuber of A. konjac to the elongated tubers of A. longituberosus and macrorhizus to the bizarre clustered rootstock of A. coaetaneus. From the top of this tuber a single leaf, which can be several metres across in larger species, is produced atop a trunk like petiole followed, on maturity, by a single inflorescence. This leaf consists of a vertical leaf stalk and a horizontal blade, which may consist of a number of small leaflets. The leaf lasts one growing season. The peduncle (the primary flower stalk) can be long or short.

As is typical of the Arum family, these species develop an inflorescence consisting of an elongate or ovate spathe (a sheathing bract) which usually envelops the spadix (a flower spike with a fleshy axis). The spathe can have different colors, but mostly brownish-purple of whitish-green. On the inside, they contain ridges or warts, functioning as insect traps.

Hello Emmanuel,
fascinatingly detailed capture of this unusual plant from out of the dark, obviously taken with great technical care and deliberation. Perfect scientific documentation.
How to avoid those slight sharp shadows close to contours caused by a standard flash mounted on the camera would be a further technical challenge - well, but critizising is always easier than doing.
Thank you for this excellent exotic document.
With best regards,
Peter

Merry Christmas to you and your family!

unbelivable inflorescence, TFS this unique aroid, Ori
