A reply: "This is a narrow spathed variant of the griffithii alliance. With some variants it is difficult to assess whether they are still forms of griffithii with a narrow spathe or big forms of propinquum with a wider spathe as they seem part of a continuous variational range going from one extreme (griffithii) to the other (propinquum). I have studied this group in the Yumthang Valley and the variation is endless, particularly at the higher elevations and forms like this ultimately morph into elephas type plants. Due to this it is impossible to attach a definitive name to many plants from this valley other than that they belong to the “griffithii” group. Costatum it is definitely not as that is a Nepal endemic with thick, shiny leaves with raised veins underneath growing at much lower altitudes.
Many people look at species as fixed entities but in reality several Arisaema are still in a high state of evolutionary flux which causes some problems with identifications. The best name for this plant would probably be Arisaema griffithii aff.**** The same variational patterns for griffithii and allies occurs in the Shingallila National Park and several places in Nepal. For good photographs of Arisaema costatum in situ and the variation of the griffithii-group in Nepal see: http://www.greenmilenursery.be/photo_nepal.html Pascal" Thanks a lot, Dr. Pascal. **** On 16 June 2013 14:31, J.M.
