This large and striking species is nearly related to the East Indian 
Ch. corallina, differing especially by the dicecious fructification, by the 
imperfect structure of the foliola, and by the seeds and antheridia 
standing in clusters of two or three. It is transparent and glossy, 
without any incrustation. The seeds are, in comparison with the size 
of the plant, minute, scarcely so large as in Ch. fætida, the dark- 
coloured nut being the length of 3 a millim.

This species is nearly related to the two following, still more nearly, 
however, to Ch. Hydropitys, Reichenb., of East India and. South 
America, from which it differs by its uncoated leaves, imperfect prickles
