855* Pexjtalis 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 Pennsylv. 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. punctatum by 
some botanists, but not at all punctate, and 
very different 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
