1914] Moore,— Allies of Solidago odora a0 
To the species already enumerated is now to be added a new one, 
as distinct as S. fistulosa or S. tortifolia, and if anything more so than 
S. Chapmanit. Most striking in this new species are the very long, 
ascending branches of the inflorescence, usually arising from nearly 
the same point on the stem and gracefully curved, producing in a 
typical inflorescence an effect altogether unlike that of any other 
inflorescence in the genus Solidago, in shape suggesting an ordinary 
feather-duster or the familiar European besom, or broom made of 
fagots (the scopae of the Romans), if one may use such homely similes. 
This very distinct species was first observed by Mr. S. C. Hood in the 
vicinity of Orange City, Florida. Mr. Ivar T. Tidestrom kindly 
referred to me for study specimens of it which he collected there. 
KEY TO THE ALLIES OF S. ODORA AND S. CHAPMANII. 
a. Leaves, or at least the upper ones, entire, glabrous except for the scabrous 
margins, or with seabrous midrib. b. 
b. Leaves all entire, not clearly differentiated into upper and lower cauline; 
involucral scales not with rounded nor erose apex, generally acute. c. 
c. Stems scabrous, with minute hairs only; leaves with glabrous midrib, 
more or less prolonged beyond the apex, usually anise-scented, but 
sometimes odorless; branches of the inflorescence relatively short, 
not with a long portion below the flowers. d. 
d. Leaves alllong lanceolate or linear-lanceolate, acuminate. S. odora. . 
d. Leaves some or all of them oblong or elliptic-ovate, more often 
obtuse, at least not acuminate, and strongly inclined to be thick 
and rigid. S. Chapmanit. 
c. Stems very rough, with short but conspicuous bristly hairs; leaves 
with scabrous midrib, rounded and hardened at the tip but not pro- 
longed, and with a characteristic goldenrod odor; branches of the 
inflorescence elongate (averaging 2.3-3 dm. in length), ascending, 
with a long portion below the flowers. S. aspericaulis. 
b. Lower leaves remotely serrate, distinguished into upper and lower, often 
rather abruptly; involucral scales with rounded and erose apex. 
S. tortifolia. 
a. Leaves all minutely crenate-serrate, generally with scabrous hairs scat- 
tered over lower surface, gradually decreasing in size from base to summit. 
S. fistulosa.
