NORTH AMERICAN 
axils 1 or 2flore, flowers sessile calix unequal 
linear pubescent — in the Alleghany mts. bipe- 
dal, corol rufous red subequal 51obed, berries 
purple. Of this Genus our botanists admit only 
two species perfolmtum and angustifolium, 
but the first also called majus by some con- 
tains many blended species, and it is hard to 
say which is meant by each, as few give origi- 
nal descriptions: this is the sp. of Elliot. 1 
shall increase this Genus to 8 sp. quite distinct* 
they are all perennial estival plants, with stem 
simple and axillary flowers, commonly found 
in limestone or sandy soils. The roots of all 
are medical and febrifuge, see my medical 
flora. 
282. Triosteum molle Raf. entirely villose 
soft, leaves subconnate broadly oblong acumi- 
nate undulate repand, villose above, tomentose 
beneath, axils triflore, flowers sebpedunculate 
—Received from Missouri, bipedal. 
283. Triosteum villosum Raf. stem striated 
villose, leaves sessile ovate acute base attenu- 
ate, smooth above, villose beneath, axils multi- 
flore upper sterile, flowers sessile, calix lanceo* 
late — in the sandy soils from Maryland to New 
Jersey, bipedal, or tripedal corol short dark 
purple, berries purple. 
284. Triosteum pumilum Raf. stem dwar- 
fish sulcate villose, leaves sessile oblong elliptic 
acute, villose beneath, axils uniflore, flowers 
sessile calix villose long linear— on the Apala- 
chian mts. of Virginia, only one foot high or 
even less, quite distinct from Tr. angustifolium, 
probably the minus of some botanists. 
285. Triosteum angustifolium L. Elliot 
& c, stem hairy, leaves subconnate lanceolate 
spatulate acuminate slightly scabrous, axils
