The genus Comanthosphace was established upon four 
species of Japanese plants, first described under Elsholtzia 
by Miquel, and subsequently referred (as one species, 
on the authority of Maximovicz) to Pogostemon by Bentham. 
That the affinity of Comanthosphace is with Pogostemon is, 
1 think, unquestionable, as is shown in the structure of 
the anthers, but it differs from all species of that genus 
in the form of the corolla, which is 5-lobed, and strongly 
pilabiate, with a prominent hemispheric lower lip, whereas 
in Pogostemon the corolla limb is nearly equally 4-fid. As 
Mr. Moore observes, Comanthosphace approaches Elsholtzia 
in the form of the corolla which is somewhat two lipped 
in that genus; but there is a wide difference between them 
in this organ, and a still wider in the anthers, those of 
Elsholtzia being ovoid or oblong, and distantly 2-celled, 
and the cells 2-valved, while in Comanthosphace, as in 
Pogostemon they are subglobose, imperfectly 2-celled, and 
2-valved. In his description of the genus Mr. Moore, by 
Marcu Isr, 1896.
