80 PLANX.E WRIGHTIAN^. VI. 



LiNOSYRis GRAVEOLENS, Torr. §* Gray, Fl. 2. p. 234 ; var. approaching L. albi- 

 caulis. Pebbly bed of a creek near Sierra de los Animos, New Mexico ; Oct. 

 (1184.) — " Stem erect, branched, 4 to 6 feet high." There is a slight pubescence 

 on the tube of the corolla, but not the long, cobweb-like hairs of S. albicaulis.* 



L. puLCHELLA, Gray, PI. Wright, p. 96. Sandy ridges along the banks of the 

 Rio Grande, near Frontera; Nov. (1185.) — No. 287, the locality of which was 

 accidentally omitted, was gathered on prairies below El Paso. 



L. Wrightii, Gray, PL Wright, p. 95, & var. foliis inferioribus pinnatifido-den- 

 tatis. — Low banks of the Rio Grande, New Mexico ; growing in large bunches ; 

 Nov. (1186.) — A few specimens of a minutely hirtello-scabrous vaiiety of this 

 species were gathered on the Rio Grande near Dona Ana, in July ; which probably 

 connects L. hirtella with this species. 



L. 1 CARNOSA (sp. nov.) : glabra ; caulibus e basi sufFrutescente ramosissimis dif- 

 fusis rigidis, ramulis patentibus monocephalis ; foliis linearibus (subteretibus ■?) 

 carnosis glaucescentibus, raraealibus sensim abbreviatis subulatis ; involucro cam- 

 panulato 40-floro, squamis 3 - 4-seriatis lanceolatis acuminatis ; acheniis sericeo- 

 pubescentibus. — Low, subsaline valley, Avest of the Chiricahui Mountains, Sonora ; 

 Sept. (1187.) — I am doubtful of the genus of this plant, which looks as if it 

 might be a Tripolium without rays. The rigid, but herbaceous, spreading stems 

 are two feet or more in length, bearing numerous alternate leaves, which were fleshy 

 and appear to have been terete or laterally flattened ; the lower ones an inch long ; 

 those of the flowering branches reduced to minute subulate bracts. The herbage 

 has a strong saline and acrid-bitter taste. The involucre is 3 or 4 lines long, a 

 little shorter than the disk ; the scales regularly imbricated and appressed, the ex- 

 terior successively shorter. Pappus copious, tawny. Appendages of the style 

 slender, linear-subulate. 



L. (Aplodiscus) ramdlosa ; Gray, PI. Wright, j). 97. Aplopappus (Aplodiscus) 

 ramulosus, DC. ! Prodr. 5. p. 350. Ravines, at the base of the Organ Mountains, 

 New Mexico; April. (1400.) — Stems 1-2 feet high, much branched. Plant 

 with somewhat the habit of Aster multiflorus. 



Aplopappus (Ericameria) laricifolids (sp. nov.) : fruticosus, humilis, fastigiato- 

 ramosissimus, glaber ; foliis confertis angusto-linearibus basi attenuatis mucronulatis 

 integerrimis rigidis uninerviis crebre punctatis subresinosis ; capitulis ramulos folio- 

 sos terminantibus corymbosis ; involucro turbinato disco breviore, squamis 3-4- 

 seriatis lineari-subulatis appressis ; ligulis5-6; fl. disci circiter 12; acheniis seri- 

 ceo-villosis oblongis. — On mountains, at Guadalupe Pass, New Mexico ; Oct. 

 (1188.) — "Shrub a foot high, very much branched." Leaves 6 to 9 lines long, 

 less than a line wide, very much crowded on the branches, but not fascicled. 

 Heads 4 lines long, fastigiate-corymbose. Ligules 2-3 lines long. Appendages 

 of the style in the disk-flowers linear, rather obtuse, shorter than the long and 

 linear stigmatic portion. Bristles of the pappus not veiy copious, slender and 



* Linosyris serrulata, Torr. in Stanshury^s Rep. p. 289, is only a form of L. pumila (Chrysothamnus 

 pumilus, Nutt..), the L. viscidiflora, Torr. ^ Gray.
