Allied to Diplospora viridiflora DC., but distinguishable from it by the 

 much larger flowers with pubescent corolla-tubes and much longer exserted 

 filaments. Also near Diplospora pubescens HOOK. f. (Fl. Brit. Ind. III. p. 124), 

 in the obscurely 4-lobed calyx and corolla tube with villose throat, but greatly 

 different from it by the smaller quite glabrous leaves with a cuneate base.
