Amorphophallus bulbifer (Roxb.) Bl.
This is A. bulbifer, although at times it appeared to be A. muelleri.
After reading Aroideana Vol. 19, it is quite clear that it is A.bulbifer
There is also another page with a positively identified A. bulbifer.
Spider mites sometimes attack emerging seedlings. Aphids are moderately fond of this species.
A.bulbifer definitely dislikes low humidity - the leaflets may partially desiccate; this seems to be more pronounced in low light. Also, in low light, the leafes become exceptionally dark green, with nicely contrasting pink margins. Such plants have to be moved to brighter light very gradually. In bright light, the leaves are bright green, with pinkish margins less pronounced.
|This is a fairly mature A.bulbifer. In 1995, it grew to about 4.5 feet in height (the stalk itself was slightly over 3 feet long). By some accounts, bulbifers do not grow as large, but maybe this one liked being planted in pure compost. In spring 1996, it bloomed.|
|This is why a bulbifer is a bulbifer. It's got bulbils. Here's the bulbil on the tip of the main stalk. A. muelleri also has bulbils, but is not a bulbifer.||
Closeup of the stem pattern. This variation has very little dark color; some others have significantly more of it.
|Some more bulbils can be found on the leaf.|
|This is a close-up of barely unfolded leaves of a small A.bulbifer. They are really this day-glow bright green. Furthermore, the leaf edges are pinkish-purple. Too bad that the photos got over-corrected in development and the edges are not as visible as they should be...|
