Dear John
Have just returned from south-east Tibet and read your message about ACE
2101 - a friend of mine gave me some seed of this collection which like
yours has flowered for the first time this year. The plants - 2 - are
indistinguishable from A consanguineum from my Bhutan-collected seed.
Leaf has 20 radiate leaflets with 1" tip extensions. The friend died so
I am unable to determine whether he had different forms. I was also
given ACE 2030 which looks identical to 2101.
I also have A echinatum from one of my Bhutan collections which is
nothing at all like your description - mine corresponds fairly well to
Pradhan's description, spathe is green with an area of black inside the
spathe blade; whole plant is small <9" and it could not be described as
