Raf.-—Germandree. Rob. p. 300. Many stems, 
two or three feet high, angular ; leaves three 
inches long, approximated. Grows near woods ; 
flowers white diluted with red.

summis utrinque canis, verticillis multifloris, 
staminibus exertis remotis. Raf.—-Menthe pana- 
chee Rob. p. 380. Stems bushy, brown, three 
or four feet high, leaves soft; the middle ones 
are partly white above, which give the whole 
plant a singular appearance of being sprinkled 
with flour ; flowers nearly all terminal, calyx 
five-toothed, neally labiated ; the three upper di¬ 
visions approximated and concave : corolla large, 
white, slightly dotted of purple. Blossoms in 
August and September. The whole plant is very 
odoriferous, and it has a taste nearly similar to 
M. piperita ; however, the habit of the plant 
and the flowers, make me doubtful of its being 
a real Mentha ; it might be a Stachys,? It has 
much likeness with Stachys feniculum of Pursh.
