The flowers of L. alatuft appeal' to he protandrous. Wlien the flower expands 

 the corolla-lohos are reflexed, the filaments remain connate in their upper part round 

 the style, and the antliers open. The flower at this stage is regular. After a time 

 the corolla-tnhe splits down unilaterally to the middle, and the filaments at the same 

 time separate from one another and become deflexed.

Tiie leaves are represented as acute in De CandoUe's figure. I have not seen 

 the type, aiul have based my description mainly on Roger's specimen, which came 

 from .T. Gay's herbarium.
