albumen. The whole plant is glabrous, but neither its male nor 

 female tlowers are known. In many of its characters it ap- 

 proaches Aspidocarya, Parabcprw, Odontocarya, and Jaieorhisa, 

 but differs from all of them in having a %ery large 1-locellate 

 chamber in the condyle of its putameu. Its name is derived from 

 piyioVfhorriJicus, xapva, niix, in allusion to its hystricoid putamen.

14. Anomospermum. 



The type of this genus is a scandent shrub which I found in 

 the Organ Mountains in 1837; other species exist in Guiana 

 and Northern Brazil. They have all oblong, stiff, glabrous, 

 subcohaceous leaves, sometimes reticulated, with rigid petioles 

 articulated on the branch in a prominent cup. The inflorescence 

 is in axillary racemes issuing from a hairy tuft a little above the 

 petiole. The male raceme, in some species, is the length of, 

 or longer than the leaf, its alternate branches bearing one to 

 three flowers, or sometimes the inflorescence is reduced to a 

 solitary pedicellated flower in each axil. The female raceme is 

 much shorter and few-flowered. The flowers are of similar size 

 in both sexes, measuring, when expanded, 2 or 3 lines in dia- 

 meter : they consist of six fleshy sepals, alternate in two series, 

 the outer three being much smaller and bracteiform ; they have
