﻿PLANTjE FENDLERIAN.E. 77 



the Arkansas; Aug. to Sept. (386.) — This is a very showy plant in cultivation. From 

 Texan seeds sown in the spring, it flowers in the autumn as an annual. 



358. Grindelia squarrosa, Dunal. Moist meadows, &c, along Santa Fe Creek; 

 June to Aug. (390.) — The lowest leaves are incisely pinnatifid in some specimens.* 



359. Heterotheca scabra, /S. isuda, Torr. <§• Gray, Fl. 2. p. 251. Low prairies 

 on the Cimarron ; August. (392.) — H. (Chaetactis) Chrysopsidis, DC., described 

 from specimens gathered by Berlandier at Saltillo, has also been copiously collected by 

 Dr. Gregg at the same place. Dr. Gregg's specimens considerably resemble H. scabra, 

 /?. : some of the ray-flowers bear a deciduous, paucisetose pappus, while others are desti- 

 tute of pappus. 



360. Chrtsopsis villosa, Nutt. Rocky and sunny hill-sides, valley of Santa Fe 

 Creek; June to Aug. (391.) — The C. villosa, /3. minor, Hook. PL Geyer, in Lond. 

 Jour. Bot. 6. p. 244, appears to me to be C. hispida. 



|361. C. canescens, Torr. <§• Gray, Fl. 2. p. 256, passing into C. foliosa, Nuu. 

 Dry prairies, Santa Fe to the Cimarron ; July to Sept. (391 b.) — Numerous specimens 

 from recent collections seem entirely to connect C. canescens, C. foliosa, and C. mollis. 

 The exterior pappus is abundantly manifest in most specimens. 



* Of Mr. Bentham's genus Perityle (in Voy. Sulph. p. 23 <$■ 119. I. 15), there are the following unpub- 

 lished species in Coulter's Californian collection ; some of which, unlike the original species, have alternate 

 leaves, and therefore agree better with Asteroideoe. 



Perittle Acnella (Harv. <$• Gray, PL Coult. ined.) : subglabra ; caulibus elongatis decumbentibus : 

 ramulis involucrisque minute glandulosis ; foliis plerisque alternis ovatis trifidis, superioribus interdum hastato- 

 trilobis ; lobis lanceolatis oblongisve acutis ; receptaculo piano ; ligulis oblongis discum vix superantibus ; ap- 

 pendicibus styli oblongo-lanceolatis acutis ; pappi aristis 2 scabris tubum corolla subtequanlibus achenio oblon- 

 go marginibus valde hispidi-ciliato dimidio brevioribus. — Spilanthes Pseudo-Acmella, Hook. Sr Am. Bot. 

 Beech, p. 150 ? 



P. leptoglossa (Harv. cy Gray, 1. c): suffruticosa ? spithama;a, cinereo-puberula ; foliis alternis (an 

 semper?) ovatis subcordatis crenato-incisis denticulatis; receptaculo convexo ; ligulis Iinearibus elongatis (cum 

 tubo filiformi £ unc. longis) ; appendicibus styli fl. herm. attenuato-filiformibus ; pappo uniaristato, arista nuda 

 corolla disci gracillima breviore achenio lineari-oblongo marginibus breviter hispidi-ciliato longiore. 



P. plumigera (Harv. 4" Gray, I. c.) : ramosissima, viscido-puberula ; foliis (ramealibus) parvis alternis 

 seu oppositis ovatis oblongisve denticulatis ; receptaculo convexo ; ligulis oblongis involucrum excedentibus : 

 styli ramis fl. hermaph. elongatis in appendicem brevem vix dilatatam obtusam desinentibus ; achenio oblongo 

 marginibus villosissimo, pilis squamellis pappi longioribus ; arista unica corollam disci aequante achenium plus- 

 duplo superante apicem versus parce plumosa. — This species seems to be nearly related to P. Californica. 

 Benth., which I know only by the published description and figure. The specimens are merely branches, des- 

 titute of lower leaves. The heads are only 2 or 3 lines in diameter. The ligules are longer than the tubular 

 portion, and much longer than is represented in the figure of the original species. The dense fringe of the 

 achenium is nearly as broad as its disk ; and the slender awn is barbellate-plumose.
