The Genus Rosea of Martius seems to me only to be distin- 
guished from Iresine by having “ polygamo-monoicous,” not 
dicecious, flowers :—a character, which, if important, is very 
difficult to be distinguished in the dried specimens. From 
all the species known to me of these genera, our plant is 
easily recognised by the larger flowers, and by their being distantly 
placed, and often but not always, solitary (rarely glomerated) upon 
the rachis of the spike. In these respects and indeed in the 
whole habit and ramification there is a striking affinity between 
I. grandiflora and the Hebanthe paniculata, Mart. Nov. Gen. tab; 
140 :—but the flowers of that plant have a very different “ cupula 
staminea.” The anthers in ours are truly one-celled, though | 
a different appearance is, by an error of the artist, given to some 
of them in the plate. The woolly hairs in the flowers are very _ 
copious, arising from the base of each of the two inner sepals. _
