Which plant species is used in 30000 B.C., Phormium or Bolbitis?
Bolbitis Bolbitis is a genus of ferns in the subfamily Elaphoglossoideae.
Physostigma venenosum Physostigma venenosum (the Calabar bean or ordeal bean) is the seed of a leguminous plant, a native of tropical Africa, poisonous to humans. It derives the first part of its scientific name from a curious beak-like appendage at the end of the stigma, in the centre of the flower; this appendage, though solid, was supposed to be hollow (hence the name from φῦσα , a bladder, and stigma).
