Dear Peter,
Aloha. Wow. Put me on your list for pre-publication of the book!
I have a Schismatoglottis that I originally got from Roberto Burle-Marx's
collection. I suspect it is allied to the variable S. calyptrata...such as
my poor knowledge of this group is. It seems to have the habit of clumping
with the mother plant declining...I have not observed the flowering
phenology in a careful fashion. I will post a photo via my wife's email to
see if you know this taxon.
I am impressed by the potential of Schismatoglottis...it obviously is an
under appreciated group. Any and all information will be welcomed. Do you
know of sources for some of the species you list? Are there any ecological
information that will aid in planting these in the ground...ie: pH, soil
type ,limestone under detritus, etc.?
I am grateful you are working on this genus. Thank you for your wonderful
response.
Aloha,
Leland
