GENERIC CHARACTER. 



Tanghinia (Aub. du Pet. Thouars). Calyx 5-partitus, persistens. Corolla decidua calyce 

 longior hypocrateriformis ; fame subpentagona dilatata 5-dentata ; limbo piano contorto 5-lobo. 

 Stamina 5 ; filamentis brevissimis dilatations tubi insertis, tuberculoque glanduloso ad basin 

 cujuscpje disposito. Antherce crassse cordiformes conniventes. Ovarium bilobum. Stylus 1, 

 tubi longitudine sequalis. Stigma capitatum bilobum, annulo glanduloso cinctum, thecis anther- 

 aram inclusum. — (Fructus ovatus drupaceus ; nux fibrosa utrinque acuta, unilateraliter fissa. 

 Seminis integumentum membranaceum fibris tenuibus tunicse nucis solummodo adhserens. 

 Albumen crassum concavum, in sicco corneum. Cotyledones plana? tenues subcordatae. Embryo 

 superus inversus. Bojer). Flor. Cab., vol. ii. p. 85. 



Calyx o-parted, persistent. Corolla deciduous, longer than the calyx, salver-shaped ; throat
