﻿PLANTS FENDLERIAN.E. 95 



Tagetes ; the pellucid glands are wanting or indistinct ; and the styles exactly corre- 

 spond with those of many Heleniese ; in which subtribe, next to Bahia, I should therefore 

 prefer to place the genus. 



f4l0. Gaillardia lanceolata, Michx. On the Arkansas near Walnut Creek; 

 Sept. (453.) 



411. G. pulchella, Foug. ; Ton: Sf Gray, Fl. 2. p. 366. On the Cimarron and 

 Pawnee Fork of the Arkansas ; Aug., Sept. (454.) 



f412. G. pinnatifida, Ton: in Ann. Lye. N. Y. 2. p. 214; Torr. fr Gray, I. c. 

 Foot of dry, stony hills, Santa Fe ; June, July. (450.) — A dwarf species, readily dis- 

 tinguished by its pinnately-parted leaves, with the divisions and rachis narrowly linear. 

 The root is probably only biennial ; the naked peduncles as long as the stems ; and the 

 rays, in Fendler's specimens, entirely yellow. It is also in Col. Emory's collection, 

 from New Mexico, and in Dr. Gregg's from Chihuahua. 



f413. G. pinnatifida, Torr.: var. minus canescens ; involucri squamis ligulas (fla- 

 vas) aequantibus vel superantibus. Seven miles east of Rock Creek, New Mexico ; 

 Aug. (451 .) — Also gathered in Fremont's third expedition, probably towards the sources 

 of the Arkansas. Specimens intermediate between this and the preceding number were 

 gathered by Dr. Gregg at San Pablo, below Chihuahua. — The naked peduncles are 

 from 6 to 10 inches in length, usually much longer than the leafy stems; so that the 

 plant approaches Agassizia, Gray fy Engelm. (in Proceed. Amer. Acad. p. 48) in 

 aspect ; but the appendages of the style, the rays, &c, are as in the rest of the genus.* 

 Cultivated from seeds gathered by Fendler, it proves to be a very ornamental plant. 



f414. G. pinnatifida, Torr. : var. foliis imis sinuato-pinnatifidis. Otherwise as in no. 

 451. Rio del Norte, at the foot of hills ; May. (452.) 



415. Palafoxia (PALiNODiAf) Hookeriana, /3. subradiata, Ton. &• Gray, Fl. 2. 



* To the subdivision Eugaillardieae, Torr. 4" Gray, I. c. belongs also the genus Cercostylis, Less., which 

 exhibits not only the style of Gaillardia (viz. a filiform hispid appendage rising abruptly from the more hispid 

 tuft which surmounts the apex of the stigmatic portion), but likewise the same corneous subulate fimbrillas of 

 the receptacle. 



t The original Palafoxia does not belong to the first section of this genus in the JF7. N. Amer., which there- 

 fore cannot retain the name of Eupalafoxia. The palese of the pappus are equal, or the alternate ones slight- 

 ly shorter in all three of the subgenera of the work above cited. In the true Eupalafoxia, containing P. 

 linearis, Lagasca (which has been found in California by Coulter and Emory, along with a striking large 

 variety ? having broadly lanceolate leaves and 30 -40- flowered heads over an inch in length), the heads are 

 entirely discoid and homogamous, two or three of the exterior flowers sometimes smaller ; the scales of the 

 oblong involucre equal; the lobes of the corolla much shorter than its elongated tubular-infundibuliform 

 throat ; and the four alternate paleaj of the pappus manifestly shorter. 



P. Hookeriana, Texana, and callosa are all very handsome plants in cultivation, in the Cambridge Botanic
