Bigelovia. COMPOSITES. 31 7 



8. B. paniculata, Gray, 1. c. Shrubby (V), minutely pruiuose-cinereous or gla- 

 brous : leaves (of the branches) linear-aliform, 3 to 5 lines long, and the uppermost 

 very short and subulate, resinous-punctate, as also the slender branchlets : heads 

 barely half an inch long at maturity, loosely panicled, 5-flowered : scales of the short 

 involucre only 10 to 12, oblong, obtuse, thin-chartaceous and pale throughout, little 

 carinate, the innermost hardly exceeding the full grown linear villous akenes : limb 

 of the corolla rather deeply 5-lobed : style-appendages long and filiform. — Lino- 

 syris tnscidiflora, var. paniculata, Gray in Bot. Mex. Bound. 80. 



California, Schott : the station unknown, but doubtless in the southern part, and probably in 

 the interior. Imperfectly known, but seemingly a quite distinct species. 



9. B. graveolens, Gray, 1. c. Shrubby, 1 to 4 feet high, when young whitened 

 /^ more or less with a close white wool, at least on the branches, sometimes becoming 



green and glabrous with age : flowering branches virgate, leafy : leaves linear (one or 

 two inches long, one or two lines wide), the broader ones 3-nerved, the narrower 

 1-nerved and at length often involute : heads half an inch long, mostly very numer- 

 ous, in corymbose clusters, 5-flowered: involucre narrow; its scales imbricated in 



5 vertical ranks, narrow-oblong or lanceolate, obtuse or hardly acute, moderately 

 carinate, thinnish, destitute of greenish tips, imbricated in 5 vertical ranks : lobes 

 of the con >lla short: akenes linear, silky-pubescent: style-appendages subulate- 

 filiform, considerably longer than the stigmatic portion. — B. dracunculoides & 

 Missouriensis, DC. Prodr. v. 329. Chrysocoma graveolens & na-useosa, Xutt. Gen. 

 Ghrysothamnus tlnicunculoides & C. speciosus, Xutt. in Trans. Am. Phil. Soc. n. 

 ser. vii. 32-1. Linosyris graveolens & L. albicaulis, Torr. & Gray, Fl. ii. 234. 



— lias a wide range, and runs into several varieties, of which the following occur 

 in California : — 



Var. glabrata, Gray, 1. c, with little woolliness, and that deciduous, at least 

 from tin; leaves and involucre, or the latter glabrous from the first. 



Var. hololeuca, Gray, 1. c. Clothed with a dense close coat of white wool: 

 scales of the involucre oblong-linear and very obtuse, only the innermost glabrous : 

 corolla with very short lobes, its tube beset with a few long and delicate cobweb- 

 like hairs. 



Var. albicaulis, < !ray, 1. c. Like the preceding variety in the white-woollincss, 

 or the leaves (becoming naked in age) and the narrower and less obtuse scales of 

 the involucre slightly or not at all woolly: corolla with rather long lobes (the 

 length double the width), its tube beset with abundant long and cobwebby hairs. 



— Chrysothamnus speciosus, var. albicaulis, Xutt. I.e. Linosyris albicaulis, Torr. 



6 Gray, Fl. 1. c. 



In alkaline soil, on the eastern slope of the Sierra Nevada, from Mono Lake to Sierm Vallej : 

 thence abundant through the interior to tho borders of British Columbia and the plains east of 

 the Rocky Mountains. The var. hololeuca, <>'.vens Valley, Dr. Born. Var. albicaulis, above 

 Donner Lake, at 10,000 feet, E. L. Greene, a rare fonu, apparently confined to n narrow district

10. B. Douglasii, Gray, 1. c. Shrubby, from 6 inches to 6 feel high, never 

 \f- woolly, glabrous, oi roughish with a minute harsh pubescence, fastigiately branched : 

 leaves varying from very narrowly to broadly linear or lanceolate, rather rigid (an 

 inch or two lung), the broader ones 3-nerved : brads a quarter to a third of an incb 

 long, mostly numerous in a close corymb or cyme, 5-flowered: scales of the invo 

 lucre oblong or oblong-linear, obtuse, rather linn, destitute of greenish tips, rather 

 few in 4 or 5 vertical ranks: lobes of the corolla rather long, spreading: akenes 

 rather hort, silky-villous : style-appendages narrowly subulate, usually only half the 

 length of the stigmatic portion. — Linosyris mscidiflora, Torr. & ( (ray, with the sj n. 

 Crinitaria viscidifiara, Hook. Fl. ii. 21, but the flowers not viscid, even the invo- 

 lucre rarely so. — Besides the smooth and glabrous ordinary form, there are in t'ali- 

 Ebrnia or on its borders, —
