Re: [aroid-l] Furtadoa
Yes, I'm back and aroiding!
If you have found Furtadoa in Thailand the it will be either F. mixta (which
is widespread but rather rare in southern peninsular Malaysia) or it will be
a new species. Whereabouts did you find the plants?
Are the leaves plain green or variegated? F. sumatrana is always
Furtadoa mixta looks like a large plant (c. 20 cm tall) of Homalomena
humilis or H. deltoidea, even in when flower. You will have to dissect an
inflorescence to be sure of the genus. In Homalomena subg. Chamaecladon the
male flowers are in a uniform mass above the females whereas in Furtadoa
each male flower is associated with a prominent pistillode, giving the male
portion of the spadix a rather 'bristly' appearance. Oh, yes, you need to
dissect an inflorescence just before or just as it opens. The inflorescences
only last a day or so and then close and then the peduncle droops. Such
post-anthesis inflorescences look fine but on opening you'll find that the
critical male portion has rotted or been eaten by the maggots of the flies
that visit and pollinate.
Another feature of subgen. Chamaecladon is that the species are very
variable in the field such that in a small area of forest it's possible to
find many different looking leaf types that, on flowering, all prove to be
the same species.
Looking forward to hearing what you have.
