﻿92 PLANTS FENDLERIAN.E. 



rymbose branches, not calculate. 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 paleee all equal and similar, entirely 

 awnless and nerveless. 



villosuli, 2-pollicares : corolla atropurpurea, ut in sicco apparct. 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-yerla.'' 1 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 leaves arc much less woolly when old ; and under this covering scattered glands, like those of other 

 Tagetineaj, 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 alveolate or 

 naked. 



CLOMENOCOMA, Cans. 



A solitary specimen of Clomenocoma aurantia, Cass., brought from Mexico by Dr. Malstead (" Plan del 

 Rio, April 16th") and which I have examined in Herl. Torr., furnishes the following particulars to the gen- 

 eric character : — Ligulse in tubulum longum gracilem sublata;. Corolla: disci tubo proprio brevissimo, fauce 

 cylindrica prselonga, lobis linearibus glabris. Styli rami fl. hermaph. elongati, lineis stigmaticis conspicuis 

 percursi, cono subulato acutissimo hispido terminati. Paleoe pappi 10, in setam mediam longissimam simpli- 

 cem vel bisetuligeram, squamellasque 2 iterum 2-3-fidas et in setas desinentes, profunde trifidoe. — Folia 

 eglandulosa. Involucrum pluriseriatim imbricatum. 



TAGETES, Town. 



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 paleoe and single awn into a tube which is 

 longer than the achenium : — 



, T. Wislizeni (sp. nov.) : annua, exigua, glaberrima; foliis alternis vel infimis oppositis interrupte pinnato- 

 partitis, segmentis 7-10 setuloso-mucronatis, minoribus subulatis, majoribus linearibus vel oblongis inciso- 

 3-7-dentatis; ramis fastigiatis in pedunculum nudum filiformem iisdem multo longiorem monocephalum desi- 

 nentibus; involucro fusiformi apice constricto breviter 4-dentato circ. 8-floro ; ligulis 2- 3 brevissimis rotun-
