94 PLANTS "WRIGHTIAN^. V. 



277. Gtmnosperma corymbosum, DC. Proclr. 5. p. 312; Torr. 8f Gray., Fl. 2. p. 

 192; Gray, PI. Lindh. 2. p. 222. Hills along the Pecos and Limpia, also on 

 the Rio Grande, in Texas. — G. multiflorum and G. scoparium, DC, are scarcely 

 distinct from this. As to De Candolle's opposite-leaved species, G. nudatum is 

 Flaveria linearis, Lag., as already referred in the Flora of North America, and I may 

 now add that his G. oppositifolium is Flaveria longifolia, Gray, PI. Fendl. p. 88. 



278. GuTiERREZiA EuTHAMiiE, Torr. 8f Gray, Fl. 2. p. 193 ; var. caule altiore. 

 Side of mountains near El Paso ; Sept. A smaller form was gathered on the 

 Limpia. 



279. G. MicROCEPHALA, Gray, PI. Fendl. p. 74, adnot. Brachyris microcephala, 

 DC. ! Prodr. 5. p. 313, non Hook. Along the Rio Grande, 60 or 70 miles below 

 El Paso ; Sept. 



280. G. ERiocARPA (sp. nov.) : diffuso-ramosissima ; ramulis divergentibus sub- 

 corymbosis capitula solitaria gerentibus ; foliis angustissime linearibus ; involucre 

 hemisphserico disco convexo brevioribus, squamis lineari-oblongis acutis ; ligulis 

 10-12; fl. disci circiter 30 ; pappo conformi e paleis circa 12 lineari-lanceolatis 

 subulatisve integris haud raro inter se subconcretis achenio turbinate villosissimo 

 dimidio breviore ; receptaculo alte conico. — Prairies along the Rio Grande, Texas. 

 (Also between Laredo and Bexar, Feb., 1828, Berlandier ; v. sp. in herb. Hook.) — 

 Stems 1-3 feet high, very leafy. Leaves an inch or less in length, half a line 

 wide, those of the branches almost setaceous. Heads barely two lines in diameter; 

 the rays linear-oblong. Achenia turbinate, 10-ribbed, very strongly silky- villous. 

 Pappus of more numerous, longer, narrower and acute palese than in the allied G. 

 sphserocephala {PI. Fendl.), sometimes all distinct, often irregularly concreted more 

 or less, similar in the ray and disk. G. sphserocephala has the receptacle equally 

 conical.* 



281. SoLiDAGo PETiOLARis, Ait. ; Torr. 8f Gray, Fl. 2. p. 203 ; var. Mountains 

 between the Limpia and the Rio Grande ; Aug. A bad name for the species, since 

 the leaves are nearly or quite sessile. This state is nearly allied to S. velutina, DC. 



282. S. NEMORALis, Ait.; Torr. Sf Gray, Fl. 2. p. 220; var. ^. & 7., verging to 

 S. incana, Torr. 8f Gray, which is probably not distinct.f Valley of the Limpia, and 

 base of the Gaudalupe Mountains ; Sept. Some of the specimens have narrowly 

 lanceolate leaves, and are S. decemflora, DC. ! Prodr. 5. p. 332, except that Berlan- 

 dier's are very starved and late specimens, having been gathered in December. J 

 De Candolle's S. puberula is also S. nemoralis, the ordinary form. 



oribus lanceolatis sessillbus integerrimis mucronatis ; involucri squamis lineari-lanceolatis acutis hirsutis ; 

 ligulis albis. — Mexico, Gregg. 



* No. 538 of Gregg's Mexican collection (from near Saltillo) accords rather better than Coulter's 

 No. 315 (from Zimapan) with the character of Hemiachyris glutinosa, Schauer in Linnaa, 19. p. 724 ; 

 but both differ from it in having a pappus in the ray as well as disk, and of more numerous small paleas. 



t Solidago mollis, Barl. hid. Sem. Hort. GmlL, as I learn from specimens of the plant cultivated in the 

 Botanic Garden of Halle, 1849, is exactly S. incana (var. «.), Torr. Sf Gray, FL, which name should 

 give place to Bartling's, if the species be distinct. 



I Solidago puncticulata, DC. ! I. c, which is compared with this, is S. odora.
