NATURAL HISTORY OF PLANTS. 



insertion and the perianth are nearly as in Bimorphandra. But the 

 stamens are all ten fertile ; their free filaments are surmounted by 

 introrse two-celled anthers, whose connective is tipped by a terminal 

 apiculus. The sessile or subsessile ovary ends in a short thick style, 

 with a more or less oblique concave apex covered with stigmatic 

 papillae. The ovary contains either two transverse or descending 

 ovules whose micropyles look upwards and outwards, or only one, 

 often ascending when adult with its micropyle downwards and 

 inwards. The oblong compressed coriaceous indehiscent (?) fruit 

 contains one or two compressed suborbicular seeds, whose embryo is 

 surrounded by a thin cartilaginous albumen. Two species of this 

 genus are known. 1 



The floral receptacle of Er/jf/irophlce/nir (figs. 133, 134) is far 

 more concave than in the two preceding genera: and hence the 



Evyihrophloeum guineense.

insertion of the perianth and androceum is far more decidedly 

 perigynous. The receptacle is lined with glandular tissue ; on its 

 rim are inserted a five-toothed gamosepalous calyx, five equal petals, 

 at first slightly imbricate but later valvate, and ten free stamens, five 

 superposed to the teeth of the calyx, and five shorter to the petals ; 

 the filament of each stamen bears an introrse two- celled anther of
