This beautiful and very distinct genus agrees with the 
two preceding genera, in having the receptacle thickly beset 
with lanceolate, distinct, pointed paleas ; but its capillary 
pappus, its parted stigma, and the uniformity and texture 
of its florets, distinguish it essentially from both. The 
briUiant white heads of flowers has suggested the name of 
Leucostemma, which I have applied to the genus. It is de- 
rived from MvKo?^ albus, and <rrii^if^y corona.
