tured, the central bar thickened. Staminodes connate, forming an 

 excavate, rather fleshy, pubescent organ with two thick subulate points 

 at the tip, and one on each side below. Stamen-filament extremely short. 

 Anther long, oblong, pubescent, the crest oblong, truncate, obscurely 

 3-lobed, with four nerves. Stigma very large, triangular, excavate in
