The distinction of this Tribe depends upon the peculiar state of the 
caudicula, which is not transparent, and connected with the stigma by 
means of a gland as in Vande, but powdery, and very often turned back 
upon the face of the pollen masses. Some of the genera, such as Ceratium, 
in which this caudicula is very much reduced in size, approach Malaxidee ; 
nevertheless the limits of the Tribe seein sufficiently well defined.
