BIADELPHIA PENTANDRIA. 
1. Carneum. 
P. spica cylindrica, 
pedunculata ; bracteis 
subulatis, longitudine 
calycis ; calycibus gla- 
bris ; foliolis lanceo- 
latis. 
Mich. 2. p. 49. Pursh 2. p. 46l. 
Spike cylindric, pe. 
dunculate ; bracteas 
subulate, as long as the 
calyx; calyx glabrous; 
leaflets lanceolate. 
Nutt. 2. p. 85. 
Root perennial. Stem 2 — 3 feet high, glabrous. Leaves in alternate 
fasciculate clusters, pinnate, generally with three pair of leaflets and an 
odd one. Leaflets linear lanceolate, entire, small. The common petiole 
rarely an inch long, entire, glabrous. Flowers in terminal cylindrical 
heads. Bracteas subulate, when young much longer than the calyx, giv- 
ing the spike a square appearance, but not longer than the calyx when in 
flower. Calyx ovate, striate, glabrous, 5-toothed, deeply cloven on the 
upper side, the teeth when young pubescent on the inner surface. Pe- 
tals obovate, on long claws, the upper one larger than the rest and slight- 
ly emarginate, all brilliantly white. Stamens and Style nearly as long 
as the corolla. 
This plant which grows in great abundance on the sand hills between 
the Flint and Chatahouchie rivers, notwithstanding the colour of its co- 
rolla agrees in too many respects with the P. Carneum of Michaux to be 
separated from it without a careful examination of his original plant. 
Specimens which I have received from Florida under this name differ 
much in their general aspect from the one I have described. — There are 
probably still some unknown species in the extensive pine forests along the 
southern line of Georgia and in East-Florida. 
Flowers July — August.

culato-corymbosis; ca- 
lycibus plumosis ; fo- 
liolis linearibus, muti- 
eis. 
Peduncles in pani- 
cled corymbs ; calyx
