figure whicli seems to be this species. In Fi. B. Ind. the plant is put to 

 T. paucijlora^ W. & A., and to this latter name is also referred (in Index 

 Kewensis) Cynanchiim bracieatinn, Thunb. Cynattc/ium Jla^'cns, Thunb., 

 is almost certainly this, which Thunberg could scarcely miss collecting on 

 the route he travelled, and he gives for it the S. name, 'Binnuga' 

 (Bin-nuga). 



Possibly a maritime variety of T. asthinaiica, but very different in 

 appearance.
