late. Stamens half as long as tube of corolla; anther cells 
divaricate. Disk annular. Ovary linear; lobes of stigma obo- 
vate, 1' long; ovules irregularly pluri-seriate tothe cell. Cap- 
sule not seen.—Leaves and inflorescence are very similar to 
those of Couralia rosea (Tecoma rosea Bertol.; Tabebuia 
rosea DC., § COURALIA), represented in the series of erszc- 
caté 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.
