acute, the lower spa*

involucrum viscidly pu-

Inula Mariana. Sp. pi. 3. p. 2099. Mich. 2. p. 122. Pursh, 2. p. 531. 
Root perennial. Stem one to two feet high, simple, sparingly clothed 
with long lanuginous hair. Leaves clothed in a similar manner, particular- 
ly on the under surface. Corymb composed of a few heads. Peduncles 
and back of the leaves of the involucrum covered with viscid glands. Invo- 
lucrum many leaved, imbricate, leaves linear-lanceolate. Florets of the ray 
sixteen to twenty ; of the disk very numerous, all yellow. Anthers slightly 
two-cleft at base, with the terminal appendix lanceolate, white. Stigmas 
glandular. Seeds oblong, villous. Pappus on all of the florets double, the 
exterior simple, short, the interior scabrous, not so much coloured as usual 
in this genus. 
Grows in dry sandy soils. 
Flowers August — October. 
The species which has been sent me from New-Jersey by my much es- 
teemed friend Dr. Torrey, of New-York, as the Inula Falcata of Pursh, is 
certainly a very distinct species from this. It may be distinguished as C. 
falcata foliis lineari-lanceolatis, acutis, rigidis, sub falcatis ; involucri squa- 
mis sub tomentosis. The flowers in my specimens too are smaller than 
those of the C. Mariana. 
5. Trichophylla. Nutt. 
C. pilosa; foliis ob- 
longis, obtusis, inter- 
gerrimis; corymbo sim- 
plici; involucri squamis 
angustissimis, glandu- 
losis. 
Hairy; leaves oblong, 
obtuse, very entire; co- 
rymb simple; scales of 
the involucrum very 
narrow, glandular. 
Nutt. 2. p. 150. 
Root perennial. Stem twelve to eighteen inches high, sparingly lanuginous. 
Leaves somewhat lanuginous, sessile, generally entire, the lower one attenua- 
ted at base. Corymb simple, few flowered. Involucrum many leaved, im- 
bricate ; leaves very narrow, a little glandular, and sometimes hairy. Flo- 
rets of the ray fourteen to sixteen, narrow, and perhaps longer than any other 
of our species ; of the disk numerous, all yellow. Seeds oblong, villous, 
almost hispid. Pappus of both florets double, the exterior simple, the inte- 
rior scabrous, brownish.
