855. Peutalis polystachya Raf. smooth 

 erect ramose, leaves sessile lanceolate acute 

 margin rough, sheaths scariose tubular aris- 

 tate ; racemes paniculate branched, slender and 

 lax, flowers commonly geminate, pedicels longer 

 than sheaths — from Fennsylv. to Kentucky, 

 stem bipedal with a profusion of spikes, leaves 

 1 or 2 inches long, racemes as long axilary and 

 terminal, flowers autumnal white, seeds ovate 

 oblong compressed lenticular edge thick, 



856. Peutalis palustris Raf, stem simple 

 smooth, leaves sessile lanceolate acute erect, 

 with adpressed hairs on both sides glaucous be- 

 neath, sheaths tubular ciliate ; spikes terminal 

 pedunculate 1 to 3, filiform, flowers sessile, 

 sheaths as long as flowers — a very pretty sp. 

 growing in ditches and swamps from Vermont 

 to New Jersey, deemed Polyg. punctatuin by 

 some botanists, but not at all punctate, and 

 very diflferent from the 2 punctate sp. of the 

 North and South, Pedal, leaves biuncial, flow- 

 ers rose color or incarnate, spikes slender un- 

 cial, seeds lenticular, stamens 6, It must be 

 recollected that Chulusium has 5 stamens, Peu- 

 talis 6, Heptarinia 7, Dioctis 8, and Mitesia a 

 trigone seed. As it is often difficult to count 

 the stamens and some deem them variable, all 

 those with lenticular seeds and 2 stigmas might 

 be united as subgenera to Peutalis that answers 

 to Persicaria which is not the Peach Tree ! 

 Persica. 



857. Polygonum squamosum Raf. smooth 

 erect terete ramose, branches short divergent, 

 leaves and sheaths imbricate, leaves linear o- 

 blong obtuse short, sheaths scariose scaly lan- 

 ceolate acuminate ; flowers axillary sessile — in 

 West Kentucky disc. 1818, habit quite peculiar
