I have not seen an authenticated specimen of this species. The plant collected 

 by Baines is in advanced fruit : the portions included in brackets in the above 

 description refer to it. The species is very near C. hyalina, but has less sharply 

 acute lobes to the calyx and corolla. 



10. C. cassytoides, Nees in Linncea,xx. 196 (name only). Stems 

 as stout as whipcord. Flowers sessile or nearly sessile, in laxly spicate 

 sessile 1- to few-flowered cymes, each subtended by a persistent orbi- 

 cular bract. Calyx fleshy, campanulate, barely 1 lin. long; tube very 

 short ; lobes orbicular, imbricate. Corolla li-lf lin. long; lobes oblong, 

 obtuse, shorter than the campanulate tube. Anthers sessile at the 

 throat of the corolla-tube ; scales triangular with erosulose margin. 

 Style 1 ; stigma 2-lobed. Capsule inclehiscent, ovoid in the tropical 

 African specimen, but unripe. — Engelm. in Trans. Acad. Sci. St.
