10, all thin, lanceolate, gradually acuminate, and wholly destitute of green tips, 

 except perhaps an outermost one j)assiMg into a hract : style-ajtpendages much 

 exserted, long ami subulate-IiliioMii : akenes linear, slender, silky-villous. 



Sierra Nevada at Mono Pass, at 9 to 10,0l>0 feet, Bolandcr. Mucli like Aplopappiis MacronantL 

 (which was toimd near by, ami luij^ht ahiiost as well be of this genus) ; but the heads nanuwer, 

 I'uw-llowereil, the outer .siales of liio involueio suceessivcly sliortor and not loliaueous. 



5. B. Howardii, CJruy, 1. c. Low, more or less shrubby, coated with some 

 close white wool when young, almost naked when old : leaves rigid, 1-nerved, linear, 

 1 or 2 inches long, the upper forming bracts to the somewhat spicato heads or clus- 

 ters : involucre narrow, oidy ft-lloweied ; its scales 12 to 15, regularly imbricated, 

 broadly lanceolate, nu)ro or less ctibwebby-woolly, particularly nt the nuugins, 

 abruptly and conspicuously acundnate, the outermost with a more or less foliaceous 

 appendage, the iuner with a sh^mUu- cus[> : style-ajtpondages much exserted, long 

 and subulat<'.-lilif(irui : akenes linear, silky-villous. — Linosi/ris Jlowardii, l*arry. 



Var. Nevadensis, Gray, 1. c. ^lore rigid, especially the leaves, which incline 

 to be oblanceolate and indistinctly 3-nerved : involucre more cobwebby and some- 

 times glutinous, as well as more coriaceous, and with longer-tapering somewhat 

 recurving tips. 



Sierra Nevada, at Mono Pass, alt. 10,000 feet : a stunted foiTn, Bolander. The var. Ncvadaisis 

 at Ebbett's Pass, alt. 9,000 feet {Brewer), and in N. W. Nevada, Bluoiucr, Anderson, IVutson, 

 fic. The tyi)ical form chiitly in Colorado and N. K. New Mexico. Heads 8 or 9 lines long. 

 This var. J^'cvudcimis, which is at least a very marked variety, inidines to have its involuuial 

 scales in 5 rather obvious vertical ranks, and so connects the preceding with the succeeding 

 species. 



G. B. ceniminosa, Gray, 1. c. Shrubby, fastigiately much branched, 2 or 3 

 feet high, minutely woolly-pubescent when young, becoming glabrate and usually 

 balsamic-resinous with age : leaves liliform or narrowly linear with involute margins 

 (an inch or less long) ; those of the ilowering branches scattered, their tips often 

 recurved or uncinate : heads in snudl and ludved terminal clusters, barely 3 lines 

 long, O-llowered : involucre very juurow, resiuotis ; tho lanceolate carinate Bcale.s 

 imbricatcnl in 5 .strict vertical ruidis, yiillowisli, tlio keel exteiuled into a loug and 

 nleudcr recurved tail like aciimiimtiou : limb of the cm'olla rather deeply C-lobed, its 

 lobes linear-lanceolate : ovary silky-pubescent : pappus rather scanty : style-append- 

 ages very slender. — Linusyris ceruminosa, Durand & Ililgard, PI. Heerm. and iu 

 Pacif. II. Pep. V. 9, t. 6. 



Tejou Pass, Dr. Ileermann ; who only has as yet collected it. 



n. DEi'UES.SA, Oray, 1. c, Nuttall's Chrysotluminus dcpressus, one of the three species with gla- 

 brous akenes as well as with involueral scales 5-rankeii and tai)er-pointed, is said by Nuttall in 

 PI. Gambel. to have been collected "in the Sierra of Upj)er California." This nuist be wrong ; 

 for Dr. Gambel's own specimens are ticketed " Ivocky Mountains," and were in all jnobability 

 collected in the mountains of New ile.xico, where alone others have met with this species. 



7. B. teretifolia, Gray, 1. c. Shrubby, corymbosely very nnich branched, a 

 foot or les.s in height, coi)iously balsamic-resinous, glabrous : leaves liliform, obtuse 

 or somewhat thickened upwards, half an inch to an inch long, thickly resinous- 

 punctate, minutely pruinose-hoary, but soon coated with transparent resinous exuda- 

 tion : heads almost lialf an inch long, numerous in somewhat spicate or racemose 

 clusters, 5-llowere(l : involucre very narrow; its scales imbricated in 4 or 5 vertical 

 ranks, carinate, all with small and abrupt thickish obtuse green tips, the inner 

 linear-oblong, the outer successively shorter and passing into very short scale-like 

 bracts : lobes of the corolla very short : akenes linear, silky-jjubescent : style append- 

 ages long and filiform. — Linost/ris teretifolia, Durand & Hilgard, 1. c. t. 7. 



Common on tho bare mountains around Tejou Valley, Dr. Ileerwann. "A small shrub, 

 strongly varnished and smelling of fir-balsam, covering extensive tracts of land." Also collected, 

 but past flowering, at Union Pass, Arizona, by Dr. E. Palmer. The small green tip of tlie invo- 

 lueral scales commonly bears a gland.
