Re: Which back issues??
Sorry to cause you confusion when I hoped to help!
There is a bit of a mess in cultivation surrounding the genera related to
Rhaphidophora. While most folks recognize Monstera deliciosa, the other
genera (Rhaphidophora, Rhodospatha, Epipremnum, Scindapsus, Amydrium,
Anadendrum, Alloschemone) are frequently cultivated under the wrong names.
The plant you grow with white variegated leaves isn't a member of the genus
Rhaphidophora (restricted to the old world tropics and defined by having
fruits with many small starchy seeds) but is a member of the genus Monstera
(restricted to the tropical Americas and defined by having fruits with few,
largeish, starch-less seeds.
There are couple of books you should try to get. One is The Genera of
Araceae by Mayo, Bogner & Boyce published in 1997. It's available through
the Society and while not cheap is a complete guide to the genera with many
illustrations (but won't help you to name species). Another book you should
try to get is Deni Bown's Aroids - Plants of the Arum family, which is due
to be published in a much expanded second edition in September this year.
Naming plants to species is often quite a time consuming job and is hampered
by most of the literature for the task being published for the scientific
market in the form of revisions of genera. However, most of the folks
writing the species-level revisons of Araceae are subscribers to aroid-l
(Tom Croat, Wilbert Hetterscheid, myself) and often a request on the site
will illicit replies from these folks.
Hope this helps some
ps You should also dent your credit card and order the entire back run of
Aroideana - it's an incredible source of info.
