92» - PLANTE FENDLERIANE. 
rymbose branches, not calyculate. Involucre composed of 14 or 15 oblong-lanceolate 
scales which are concreted into a campanulate cup but pretty distinctly occupy two series, 
the exterior with their margins partly free, each bearing about four large and round 
glands. . Rays 14 or 15, nearly 4 lines long, golden-yellow, as well as the numerous 
disk-flowers. Pappus scarcely half the length of the proper tube of the corolla, one sixth 
of the length of the nearly glabrous achenia; the palez all equal and similar, entirely 
awnless and nerveless. 
villosuli, 2-pollicares: corolla atropurpurea, ut in sicco apparet. In Mexico. — This plant remains unknown 
to botanists, unless the following, which is certainly congeneric, should prove to be the same species.

Dry valley and highlands near Buena Vista, Coahuila, Dr. Gregg; March. Called “ Contra-yerba.”: Ex- 
cept as to the concreted pappus, and the pinnated leaves, which do not appear on the flowering branches and 
might be overlooked, this plant nearly agrees with the brief characters of T. setifolia, given by Lagasca. 
The lower leayes are much less woolly when old; and under this covering scattered glands, like those of other 
Tagetinee, may be discerned. The size of the heads in Lagasca’s plant is not mentioned. In this they are 
only two lines long. The minutely 1 -—2-bracteate involucre also loses its woolly covering, and shows one or 
two large glands near the apex of each component scale. The receptacle is flat, and minutely alsagiate or 
naked. ; 
: CLOMENOCOMA, Cass. 
a ae A solitary specimen of Clomenocoma aurantia, Cass., brought from Mexico by Dr. Halstead (“ Plan del 
ee Rio, April 16th”) and which I have examined in Herb. Torr., furnishes the following particulars to the gen- 
is b> a eric character : — Ligulz in tubulum longum gracilem sublate. Corolle disci tubo proprio brevissimo, fauce 
eylindrica preelonga, lobis linearibus ,glabris. Styli rami fil. hermaph. elongati, lineis stigmaticis conspicuis 
percursi, cono subulato acutissimo hispido terminati. Paleze pappi 10, in setam mediam longissimam simpli- 
cem vel bisetuligeram, squamellasque 2 iterum 2-—3-fidas et in setas desinentes, profunde trifide. — Folia 
: eglandulosa. Involucrum pluriseriatim imbricatum. 
TAGETES, Tourn. 
The pappus in this genus is remarkably various. The subjoined species, which has the aspect of T. mi- 
crantha, Cav., is peculiar on account of the complete union Of the pale and single awn into a tube which is 
longer than the achenium : —
