Ashwini, The first picture of the narrow, small inflorescence is what is considered propinquum. The problem is that griffithii and propinquum are not well defined species and seem to be part of a cluster of variants. Apart from the “classic” propinquum and griffithii there are numerous intermediate forms that can’t be classified well and should be considered part of a variational range between propinquum on one end, and griffithii on the other extreme. Classic griffithii has a short peduncle yet there are several forms, particularly at the edges of Yumthang valley that have peduncles well above the leaves. Appendix length (the “thread”) is also variable as is the color. I have studied this group on several fieldtrips to W Bengal, Sikkim and Nepal and failed to find stable characters to use for species delimitations, all characters vary.
Some species groups in Arisaema are in an evolutionary flux and the normal practice of well defined species in other plant genera doesn’t always apply to Arisaema so the best way to deal with it is the use the “griffithii-group” designation for the other pictures you show. We are used to be able to apply a specific name to a specific plant but that is not always possible in Arisaema. That doesn’t mean we need new names, it does mean we need new concepts of dealing with variable species groups. So I can fully understand your confusion. Pascal From: "J.M.
