genus to Dr. Henry P. Sartwell, of Penn Yan, New York, onc of my earliest and 

 most valued botanical correspondents, a zealous student and collector of the plants 

 of Western New York, and author of the excellent Carices Amerkcc ScptentrlunaUs 

 Exsiccatay of which two volumes have already appeared. 



387. Bahia pedata (sp. nov.) : annua, puberula; caule erecto apice nudiusculo 

 corymbosi-oligocephalo ; foliis alternis petiolatis pedatisectis, segraentis obovato- 

 oblongis obtusis brevibus parce insico-dentatis lobatisve, fol. suprem. lincaribus sub- 



mtegernmis 



involucro laxo disco breviore, squamis 



oblongis 



obtusis ; acheniis 



parce pilosis ; pappi paleis 10-12 obovato-oblongis obtusis tubo corollse disci brevi- 

 oribus. — Betweeu W. Texas and El Paso ; the record of the locality lost. — Stems 



Leaves about an inch long and wide, trisected, with the lateral 



about a foot high. 



divisions two-parted or two-cleft, and the middle one 3 - 5-lobed or incised, all the 

 divisions or lobes obtuse ; the upper leaves smaller, with narrowcr divisions, gradually 



reduced to mere bracts. 



Peduncles one or two inches long. 



Heads about the size 



of those of B. absinthifolia, No. 379 ; the yellow rays, «S:c. similar. Involucre almost 

 glabrous ; the scales about 10, membranaceous, lax, two lines long, nearly uniserial. 

 Pappus one third of the length of the achenium, shorter than the glandular propcr 

 tube of the disk corolla ; the palese with an evident midnerve wliich is thickened at 

 the base. — This is a manifest congener of Bahia ambrosioides and B. absinthifolia, 

 although only minutely pubescent. Before observing the pappus I had taken it for 

 the ambiguous plant which, in Flantce FendleriarKS, p. 104, I had callcd Amauria % 

 dissecta. Indeed, the latter, although probably a distinct species (Iiaving more dis- 

 sected foliage, &c.), is to the former just what Monolopia lanceolata, Nutt. ! Fl. 

 Gamb. {== 323, California, Coulter), having discrete scales of the involucre, is to 

 Bahia sect. Eriophyllum; or what Lasthenia (Hologymne) glabrata is to Lasthcnia 

 glaberrima and obtusifolia ; what Baeria, Fish. ^ Mci/er, is to Burrielia proper ; 

 Burrielia (Ptilomeris, Nutt.) calva, to the other species of that secdon ; Hecubaea, 

 DC, to Helenium; Acarphgea, Fl. Fendl, to Chsenactis"; Sabazia urticaefolia, DC, 

 to Galinsoga parviflora; Oxyura, DC, to Layia {Groj/, FL Fendl. p. 103); Coino- 

 gyne, Less., to Jaumea; Villanova, La^., to Achyropappus ; * and Thelesperma, 



sect. Abuceros, p. 109, to the rest of that genus. 



388. Baileya multiradiata, Harv. §• Graj/, P/. Fendl. p. 106, adnot. ; Torr. in 



Emo

The scarious persistent rays are very numerous, in several series. 

 389. B. pleniradiata, Ilarv. 8r Gray, l. c. Valley of the Rio Grande, 25 miles 



below El Paso ; Sept. 



, Varilla Texana (sp. nov.) : suffrutcscens, humilis ; foliis plerisque alternis 

 carnosis obtusis ; pedunculis solitariis ramos terminantibus prselongis monoccphalis ; 



capitulo ovoideo ; pappo nullo.
