34 LEAFLETS. 



I shall first giye account of the few species that are marked 

 by a narrow and spreading foliage. In this one particular they 

 recall P. Hartwrighiii. It has this same characteristic ; but it 

 has two other important peculiarities which these fail to exhibit. 

 I shall indicate them later. 



P. KBMOTA. Stem rather slender, 1 to 2 feet long, decum- 

 bent, the nodes enlarged, internodes 1 to 2 inches long, glab- 

 rous, many-angled ; leaves lanceolate, acute, about 6 inches 

 long, thinnish, without obvious petiole and spreading away from 

 the stem, glabrous above, except as to the midvein and veinlets, 

 bhese all beset by a single series of short hair-points, lower face 

 puncticulate, the broad midvein appressed-setose and the veinlets 

 very minutely so ; margin serrulate by appressed short hairs ; 

 ocrese sparsely strigose, the hairs long, closely appressed ; spikes 

 linear, their peduncles sparsely hispidulous ; bracts with scat- 

 tered hairs on the back, not ciliate. 



Westbrook, Maine, July, 1897, P. L. Eichter, the type in 

 U. S. Herb. Information as to habitat, always valuable, the 

 collectors seldom give, much to the regret of those who study 

 plants. I have a suspicion that this plant is riparian, or else of 

 swampy land. 



P. Nov^^E Anglic. Apparently upright though slender, the 

 internodes 2 to 4 inches long, strongly striate-angled, glabrous ; 

 leaves ascending rather than widely spreading, broadly lanceo- 

 late, 7 or 8 inches long, including the petiole (this 1 inch or 

 more), thin, glabrous but puncticulate, the midvein beset with 

 an appressed murication especially beneath, the whole margin 

 sharply serrulate-scabrous with well developed and closely set 

 but short setif orm hairs ; spike large, linear, more than 3 inches 

 long, its peduncle glandular-hispidulous ; bracts small, nearly 

 or quite glabrous, or perhaps sometimes quite strigose- hairy. 



South Hadley, Massachusetts, A. C. Cook, 1887, the type in 

 U. S. Herb., where also exist some mere fragments by Oakes 

 from Wenham Pond in the same State, which may or may not 

 belong here. Only a floral leaf is shown in tha fragments, and 

 the veins of these develop something more like a hairiness.
