for the malaysia peninsular just one variety
M.tuberosa 'armata'
for the sarawak 3 possibility
M.tuberosa 'armata' ; M.tuberosa 'bracteata' ; M.tuberosa 'apoensis'
in sarawak , near what town ?
have you a macro to the clypeoli and alveoli ( on the stem ) ?
but you have reason on the specie , in this region you have just tuberosa , you told me
irian jaya or papua new guinea it would not have been the same thing
