265. BRUNELLA OBTUSIFOLIA 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, cstival, 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 obtusifolia 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 ureeolate, tube of corolla slen- 

 der strait. 



267. BUCHNERA ANGDSTIFOLIA 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. CUPHBA ALBIDA Raf. stem simple hum- 

 ble pauciflore, leaves petiolate ovate lanceolate
