Bat DESCRIPTIONS OF NEW SPECIES 
Has. With the above, and on the plains of the Oregon. About a foot high, very similar to the 
preceding, but with the leaves strongly serrated. Pappus rufous, very rigid; involucrum obconic. 
These three species have a strong resemblance to Grindelia, are all more or less sluggeus and 
resinous, so as to have a bitterish taste; the leaves in the present species are often sprinkled 
resinous atoms. 
Homopappus? spathulatus. Solidago spathulata, Decanp., Vol. V., p. 339. 
I have not seen this plant, but from the character given, and the large number 
of florets, it appears to belong to this genus. Is the pappus setose? 
Homopappus? squarrosus. Aplopappus squarrosus, Hook. and Arnot. Bot. 
Beech., p. 146. 
§ I. *Myrtantuus.—Capitulum nearly spherical, with many narrow rays; dis- 
cal florets all fertile; pappus barbellate towards the apex, persistent; achenium 
compressed, angular ; involucrum foliaceous.—With the habit of the preceding. 
Homopappus *racemosus; smooth, summit of the simple stem and NEON gi 
crum pubescent; leaves lanceolate, serrate, acute; above oblong-lanceolate, am- 
plexicaule, often nearly entire; capituli few, racemose, (three to seven); scales 
of the involucrum oblong, leafy, rather obtuse, sometimes lanceolate; rays fifa 
teen to twenty; achenium subsericeous. 
Has. Plains of the Wahlamet. About twelve to eighteen inches high. Leaves coriaceous, 
smooth, except the uppermost, narrow lanceolate, or oblong-lanceolate, acute, attenuated below in 
the radical ones. Serratures pungently acute. Flowers pedicellate. Involucrum hemispherical, 
scales imbricated in about three series. Pappus rigid, scabrous, fulvous, somewhat barbellated to- 
wards the extremities. Achenium as in the preceding, but smaller, (as well as the plant,) ene 
pale testaceous, covered with sparse hairs, which do not conceal the striatures.
