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- 

 cliniece, has its cotyledons imbedded in distinct cavities in the
