culate, glabrous on both sides, shortly ciliate. Cymes lateral at the 

 nodes, shortly pedunculate. Bracts subulate, glabrous. Pedicels about

 tips. Corolla-tube 7 lin. long, narrow, slightly inflated at the base, 

 slightly dilated at the mouth ; lobes (H lin. long, about J lin. broad, 

 connate at the tips, becoming free with age, glabrous. Inner coronal- 

 lobes elongated, about 2 lin. long, much exceeding the staminal-column, 

 otherwise undescribed.

The liberation of the coronal-lobes with age is, so far as I am aware, unique in 

 the genus, and may have been caused by pressure in the process of drying.
