The flowers of ZL. alatus appear to be protandrous. When the flower expands 
the corolla-lobes are reflexed, the filaments remain connate in their upper part round 
the style, and the anthers open. The flower at this stage is regular. After a time 
the corolla-tube splits down unilaterally to the middle, and the filaments at the same 
time separate from one another and become deflexed.

The leaves are represented as acute in De Candolle’s figure. I have not seen 
the type, and have based my description mainly on Roger’s specimen, which came 
from J. Gay’s herbarium.
