in Pyenarrhena and Antitaxis, and embracing the filaments, as 
in the latter genus; the filaments are thick and fleshy, flat in- 
side, very convex outside; the anther, as in Anelasma, is sub- 
globose, formed of two collateral cells semiimmersed in the 
gibbous, incurved, clavated apex of the filament, and it opens 
horizontally by an introrse transverse suture into two gaping 
valves, each cell being rendered bilocellate by a semiseptum, as 
in Anelasma, Antitaxis, and Pycnarrhena. The flower in its 
structure thus most resembles that of Anelasma, only provided 
with petals, but still more that of Antitazis, only that the floral 
parts are there tetramerous. 
These differences are so many and so manifest that they 
justify the maintenance of Elissharrhena as a genus distinct 
from Anomospermum. I have remarked, under Sciadotenia 
(vol. xix. pp. 325, 327) the analogy that exists in several points 
between it and Elissarrhena, both from Guiana.
