late. Stamens half as long as tube of corolla; anther cells 

 divaricate. Diskannular. Ovary linear; lobes of stigma obo- 

 vate, l^ long; ovules irregularly pluri-seriate to the celL Cap- 

 sule not seen. — Leaves and inflorescence are very similar to 

 those of Cottralia rosea (Teconia rosea Bertol. ; Tabebitia 

 rosea DC, § Couralia), represented in the series of exsic- 

 catcB by nos. 3,111, 4,912, 5,047, 5,388. -That species differs 

 by glaucous veiny leaflets, glabrous inflorescence, bilabiate 

 calyx, uniseriate ovules to the placenta; the last character 

 and the loculicidal dehiscence of capsule, ex descr., seem to 

 warrant its transfer to Couralia.
