I addressed this to Anna Haigh at the Kew but I welcome input from
anyone familiar with this plant. I continue to receive mail from
folks telling me the page is wrong no matter how I describe the
central stalk that supports the leaflets which are on short
petiolules.
Anna, can you pass this along to someone that can give me an
accurate answer?
I have revised my page on Zamioculcas zamiifolia several
times over whether or not the plant's central stalk is a petiole or
a or a rachis and the leaflets are petiolulate. I found this on
cate this morning and it appears it has both but I can't discern
which is which.
http://www.exoticrainforest.com/Zamioculcas%20zamiifolia%20pc.html
Zamioculcas zamiifolia (Lodd.) Engl. sec CATE Araceae, 2009
Tuber subcylindric, ± 3-4 cm. in
diameter or
more, tough, woody. LEAVES: Petiole green with darker
transverse
blotches, 15-35 cm. long, 1-2 cm. in diameter near base; blade
20-40 cm. long;
leaflets 4-8 per side, subopposite, distant, oblong-ovate to
-elliptic to
-obovate, sometimes oblanceolate, fleshy, dark glossy green,
5-15 cm. long,
1.5-5 cm. broad, shortly acuminate, sessile or shortly
petiolulate, articulated
to rhachis, cuneate to rounded basally; rhachis terete, marked
like petiole.
Will you take a look at the page or ask someone that is
knowledgeable about the plant to tell me exactly where the rachis
and petiole differ?
All the rest of the material was taken from Pete, Simon and Josef's
text The Genera of Araceaa and despite the fact growers argue with
me all the time I will take their word over that of any grower that
believes this plant should b grown dry. It does grow in dry
conditions part of the year, but it is not a desert species!
Thanks a bunch!
