265. Bkunella obtusifolxa Raf. stem erect 
hairy above, leaves petiolate ovate obtuse en- 
tire or subrepand, heads oblong subsessile bracts 
scariose colored ciliate reniform acuminate ; 
calix colorate ciliate — in Pennsylvania <£c, 
more similar to Br. vulgaris of Europe than 
any other, pedal, estival, perennial, bracts and 
flowers red. These 10 sp. of Brunella (mis- 
called Prunella by error of the press) are us- 
ually blended (when seen by our botanists) with 
the Br. pennsylvanica of Muhlenberg : to unite 
such diversities is preposterous. The real 
pennsylvanica which is the vulgaris of others 
differs from this my ohtusifolia by creeping 
roots, ascending stems, leaves ovatoblong acute 
toothed at the base, &c. I have even yet some 
other American and European blended sp. in 
my herbal, or at least striking varieties, some 
with white flowers. 
266. Buchnera missurica Raf. rough pu- 
bescent, stem adscendent base hirsute, leaves 
opposite and alternate crowded imbricate lan- 
ceolate subentire, radical ovate, upper ones 
small subulate squamulose remote, flowers in 
short spike, alternate at base, bracts subulate 
short — Glades of Missouri and Illinois, pedal, 
perennial, calix urceolate, tube of corolla slen- 
der strait. 
267. Buchnera angustifolia Raf. stem vir- 
gate terete nearly smooth, naked above, leaves 
remote linear obtuse entire roughened by white 
hairs, flowers scattered sessile in the spike — in 
Alabama, sesquipedal, capsules globose in ca- 
lix ovate 51obed. These two sp. are quite dis- 
tinct from B. americana , see 298. 
268. Cuphea albida Raf. stem simple hum- 
ble pauciflore, leaves petiolate ovate lanceolate
