Texas ; Sept. Also gathered by M. Trecul in the same district. — " Plant growing 

 in dense tufts, much branched from the base," a span to a foot high. Leaves crowd- 

 ed, 8 to 12 lines long, linear or filiform, fleshy, apparently terete, very obtuse. Pe- 

 duncle naked, three to five inches long. Head four lines in diameter, subglobose- 

 ovoid, larger and rounder than in V. Mexicana, the short involucre less tubinate. 

 Keceptacle, palese, flowers, &c. nearly the same ; but I find no traces of a pappus. 

 The capitula have considerable resemblance to those of Salmea, the only genus with 

 which I can compare this and the plant to which I gave the name of Varilla Mexi- 

 cana, PI. Fendl.p. 106, adnot. But the style is not asteroid in character, the achenia 

 are not obcompressed nor two-awned, &c. The present plant is truly a congener of 

 V. Mexicana, although destitute of a pappus. 



390. Artemisia filifolia, Torr. in Ann. Lye. N. Y. 2. p. 211 ; Torr. Sf Gray, Fl. 

 2. p. 417. Valley of the Eio Grande below El Paso; Sept. "Stems three to five 

 feet high, much branched." 



391. A. DRACUNCULOiDES, PuTsh ; Torr. 8s' Gray, FL 2. p. 416; Gray, PI. Fendl. 

 p. 106. Hills near El Paso; Sept. Also on the Rio Grande, Texas. 



392. A. LuDoviciANA, Nutt. ; Torr. ^ Gray, Fl. 2. p. 420. Mountains beyond 

 the Pass of the Limpia ; Aug. 



393. Gnaphalium polycephalum, Michoc. Bed of a stream, between the Pecos 

 and the Limpia ; Aug. 



394. G. microcephalum, Nutt. in Trans. Amer. Phil. Soc. (n. ser.) 7. p. 404, ex. 

 char. Valley between El Paso and the Guadalupe Mountains ; Oct. — Plant two 

 feet high, loosely paniculate-branched above ; the small heads subcorymbose. It is 

 the same species as a small unnamed specimen from California, Douglas, in the 

 Hookerian herbarium. Perhaps it is also G. ramosissimum, Nutt. 



395. G. Sprengelii, Hooh. 8f Am. Bot. Beech, p. 150 ; Torr. 8f Gray, Fl. 2. p. 

 427. Mountain valleys, beyond the Pass of the Limpia ; Aug. — Approaches G. 

 luteo-album too nearly, and probably no more than a variety of it. 



396. G. LUTEO-ALBUM, Linn. G. Sprengelii, Gj-ay, PI. Fendl. p. 107 (no. 519). 

 Bed of a stream, between the Pecos and the Limpia ; and valley of the Rio Grande 

 below El Paso ; Aug., Sept.* 



397. Senecio longilobus, Benth. PI. Hartw. p. 18; Gray, PI. Fendl. p. 108: 

 forma glabra. Valley of the Rio Grande, thirty miles below El Paso ; Sept. 



398. S. longilobus, Benth. = 397. Between the Limpia and the Rio Grande. 

 — The root seems plainly to be annual. 



399. S. longilobus, var. glabrescens, foliis majoribus. Plains between the Pecos 

 and the Limpia ; Aug. 



400. S. longilobus, var. floccoso-incana. AVith the foregoing. — It is the same 

 as Fendler's No. 470, and Gregg's No. 572. 



* 1 may here correct a transposition in the characters of Angianthus and Phyllocalymma, as printed in 

 the Conspectus of the Genera of the Angianthese, contributed to Hooker's Journal of Botany and Kew 

 Garden Miscellany, for April, 1851. It is Angianthus, and not Phyllocalymma, which has the bristles of 

 the pappus subplumose. This character should read thus : — 



Angianthus, Wendl. Pappi setaj superne subplumosse. 



Phyllocalymma, Benth. Pappi seta; nudse.
