Besides the species enumerated below, there is, in tropical Pol ynesia, a second species of this genus, 
which I discovered in Oahu, Hawaiian Islands, and which was held to be the type of a new genus, until A, 
Gray reduced it to Hrythrea, “This plant,” says the great American botanist, “was not met with by the 
naturalists of Wilkes’s expedition. But haying examined Seemann’s n. 2272 and Remy’s n. 875 from 
Oahu, I cannot regard the plant as other than a close congener of the plant which it most resembles, viz. 
Erythrea spicata, he leaves are broader and rounder, being broadly-oval; the tube of the corolla pro- 
portionally shorter, and its lobes broader; the sepals are less narrow and more carinate, or, if you please, 
winged on the back. But this varies somewhat, eyen in the sepals of the same flower, and, at most, is only 
a matter of degreo, the sepals being carinate, at the base sharply so, in #. spicata. So other American 
species affect a transition in this respect to Gyrandra, Griseb. (Zrythrea chirontoides, Torr.). Grisebach 
describes the stigma of his Schenkia as “capitulatum”’ or “crassiusculum ;” but there must be some mis- 
take or confusion here, for in Seemann’s own speecimens,which I have examined, as also in those of Remy,. 
the stigma is very large and just as in &. spicata, that is, appearing as this organ is characterized by Grise- 
bach in the section Spicaria, but upon maceration separating completely into two nearly orbicular flat diyi- 
sions. In Lyythrea generally I cannot verify the character “corolla supra capsulam contorto-marcescens,’
