Bigelovia. COMPOSITE. 317 



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

 brous : leaves (of the branches) linear-filiform, 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 viscidiflora, 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 corolla short : akenes linear, silky-pubescent : style-appendages subulate- 

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

 Missouriensis, DC. Prodr. v. 329. Chrysocoma graveolens & nauseosa, Nutt. Gen. 

 Chrysothamnus dracunculoides & C. speciosus, Nutt. in Trans. Am. Phil. Soc. n. 

 ser. vii. 324. Linosyris graveolens & L. albicaulis, Torr. & Gray, Fl. ii. 234. 



Has 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 the 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, Gray, 1. c. Like the preceding variety in the white-woolliness, 

 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, Nutt. 1. c. Linosyris albicaulis, Torr. 



6 Gray, Fl. 1. c. 



In alkaline soil, on the eastern slope of the Sierra Nevada, from Mono Lake to Sierra Valley ; 

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

 the Rocky Mountains. The var. hololeuca, Owens Valley, Dr. Horn. Var. albiaiulis, above 

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

 in the interior, extending to the eastern part of Oregon and adjacent parts of Idaho. 



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

 woolly, glabrous, or rough ish with a minute harsh pubescence, fastigiately branched : 

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

 inch or two long), the broader ones 3-nerved : heads a quarter to a third of an inch 

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

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

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

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

 length of the stigmatic portion. Linosyris viscidifiora, Torr. & Gray, with the syn. 

 Crinitaria viscidiflora, Hook. Fl. ii. 24, but the flowers not viscid, even the invo- 

 lucre rarely so. Besides the smooth and glabrous ordinary form, there are in Cali- 

 fornia or on its borders,
