Hello, John.

To answer your question, Jim Waddick wrote to the list:

By the way Typhonium diversifolium is probably an invalid
name for a Chinese species. As I recall it is listed in the Flora of
China (check that home page too) but what is grown here in the US
under that name may be T. roxburghii

So, in my researching I have found that T. diversifolium looks very
different from the plant that I have, with its stripes, and its open turf
habitat, which you described in your earlier missive:

The spathe is green with dark reddish stripes of varying
extent, with a dark spadix that emits the usual Typhonium stink. I
particularly remember seeing it in the short, overgrazed turf around Namche
Bazar in Nepal . . .

I have found pictures of the plant at this web site:

resembles very closely the plant depicted at the upper link, from the Aroid
Society. So now I must hunt the literature, and try to get a positive
identification. I am a crustacean taxonomist by training, and plant taxonomy
is coming slowly to me. Any good references that you could suggest would be

I am particularly interested in Typhoniums now. There are a large variety of
taxa, and they so far seem happy to grow for me.

Typhonium diversifolium will be best in a cool, dryish place over winter,
when it is dormant. In the wild it would be frozen in dry soil.

I am not familiar with the name T. roxburghii and would be grateful to be
informed further about it.
