1901] Fernald, — Monarda fistulosa and its allies I5 
a species distinct from M. fistulosa is probably justified. M. men- 
thaefolia, Graham, a simple-stemmed plant of the Rocky mountains, 
generally united by authors with M. mollis, is habitally so well marked 
as to deserve treatment as a variety, although it lacks any other 
constant character to separate it specifically from that plant. 
Monarda fistulosa and M. media, on the other hand, do not present 
any constant character by which they can be clearly separated. M. 
fistulosa in its typical form has lilac or salmon-pink corollas, and the 
spreading pubescence is well developed on the branches, while M. 
media has deep purple or crimson flowers and the spreading pubes- 
cence is confined chiefly to the leaves and their petioles. Numerous 
intermediate forms occur, however, so that the two plants can be con- 
sidered only extreme varieties of one species. 
The plants of the fistulosa group may now be treated as follows: 
* Pubescence, at least of the petioles and midnerves (beneath) of the leaves, 
hirsute or long-villous, spreading. 
M. FISTULOSA, L. Branches usually hirsute or villous: corolla lilac 
or salmon-pink. — Sp. 22; Benth. Lab. 316; Gray, Syn. Fl. ii. 374; 
Britton & Brown, Ill. Fl. iii. 103, except as to syn. M. mollis, Willd. 
Enum. 32; Britton & Brown l. c. as to syn. ; not L. — New Hamp- 
shire to Texas and the Rocky Mountains. Often cultivated, and only 
a roadside escape in New England. 
Var. RUBRA, Gray. Branches usually not hirsute nor villous: co- 
rola deep purple or crimson.—Gray, |. c. M. media, Willd. l. c.; 
Britton & Brown, l.c. M. fistulosa, var. media, Gray, |. c. — Maine 
to North Carolina, Tennessee and Ohio. Often cultivated and per- 
haps not indigenous in New England. 
** Pubescence minute, appressed, the leaves canescent, especially beneath. 
M. morus, L. Mostly tall and branching: throat of calyx very 
densely white-bearded: corolla lilac. — Amoen. Acad. iii. 399. M. 
scabra, Beck, Am. Jour. Sci. x. 260; Britton & Brown, l. c. M. jistu- 
losa, var. mollis, Benth. 1. c. 317, in part; Gray, |. c. (except as to syn. 
M. menthaefolia). M. fistulosa, Britton & Brown, l. c., as to syn. — 
Maine to the Saskatchewan, Oregon, and Texas. 
Var. menthaefolia. Simple or rarely a little branching: calyx 
usually less bearded at the throat. — M. menthaefolia, Graham, Edinb, 
Phil. Journ. 1829, 347 ; Hook. Bot. Mag. lvii. t. 2958. M. fistulosa, 
var. mollis, Benth. |. c.; Gray, l. c.; in part. A: stricta, Wooton,
