with coarser appressed hairs in all our specimens. It must be that 
the first description is wrong on this point. Then, the leaves are in 
no case “7—8 lines wide,” but % in. to % in.; the Angeles Bay plant 
having some leaves as wide as % in. Furthermore, the description 
has “Calyx 4-parted - . Stamens 6 according to Bonpland. 
Bes) Achene lenticular.” I have frequently found the calyx 5 
parted, stamens as many as 8, and the achenes in the Angeles Bay 
and the Orizaba plant—the latter from one of the stations cited in 
Biol. Centr. Am. 1, c.—as well as in the Texas plant, are triangular: 
all, however, of the same size, and all “umbonate,” as in the first de- 
scription. 
This species is distinguished from P. persicaria L. by its narrower, 
longer leaves, more slender spikes and smaller achenes.—J. M. Hout
