' 18. RaIGiocaRyA. 
Among the plants collected in the Niger Expedition by Mr. 
Barter is one that presents much the habit of a Chasmanthera : 
the structure of its putamen is sufficiently remarkable to make 
it the type of a new genus. The plant has a climbing Cissoid 
habit, with large, cordate, oblong, membranaceous leaves, sup- 
ported on a rather lengthened petiole. It has an axillary simple 
fructiferous raceme, longer than its elongated petiole, with a 
somewhat flexuose rachis, having alternate fructiferous pedicels ; 
the drupes are oval, slightly gibbous, fleshy, about ? inch long, 
containing an oval and somewhat compressed putamen, covered 
along its sides and over its dorsal face with crowded, erect, 
stoutish spines, truncated at their apex, and terminated by a 
short tuft of fibrous hairs; the ventral face is smooth, formed 
by a large convex raised condyle, of an oval shape, with a long 
linear foramen down the middle, opening into a large hollow 
chamber which protrudes far into the cell. The seed is oval, 
meniscoid, slightly hollow on its ventral side, showing a longi- 
tudinal raphe the length of the delicate integument which covers 
a simple albumen ; the embryo, of the shape usual in the Hetero- 
cliniee, has its cotyledons imbedded in distinct cavities in the
