spreading lobes a line long, and usually glabrous stems and leaves; 

 it grows I to 3 feet high. This is the B. graveolens Gray, really 

 (Nutt). The other species is what should be called B. nauseosa 

 (Pursh) and is the Linosyris albicmdis T. & G. This is also B. grave- 

 olens var. albicanlis Gray, and will include as varieties of it var. 

 latisguama (Gray) and var. hololeiica (Gray). The type has a fusi- 

 form corolla, lobes almost never spreading and never reflexed, usu- 

 ally closed, often short; corymbiform inflorescence, usually flat 

 topped with many heads, occasionally corymbs with few heads and 

 somewhat thyrsiform in outline; stems white tomentose. The corolla 

 is generally with closed lobes and then the fusiform character is 

 very evident; it is always a little contracted at throat. The "cob- 

 webby hairs" are found on all forms of the B. graveolens of Gray 

 and are of no Aalue. 



Biglovia albida Jones. This name was not one of my choosing, 

 but was insisted upon by Dr. Gray, who would not believe that I 

 was correct in saying that the flowers were white. I have again had 

 an opportunity to study this plant growing and find that the flowers 

 are pearly white, the dirty white color of the dried specimens is due 

 to the viscid matter of the heads coloring the flowers. The plant is 

 i^ to 2^ feet high, grows in clumps like the others, but more 

 open; it is densely fastigiately branched at the top. It is found only 

 on alkaline soil in the valleys and grows alongside of Sai'cobatiis 

 vermiculatis. It is locally abundant on the eastern side of the Deep 

 Creek Mountains, also in Spring, Antelope, and Steptoe Valleys, in 

 Western Utah and Eastern Nevada. 



Hclianthella argophylla (Eaton) Grav. This botanical nomad, 

 which has been successively called Tithonia argophylla, Encelia ar- 

 gophylla, Encelia nudicaulis, Helianthella nndicaidis, and now rests 

 under the above name as the proper one, is caespitose from a deep 

 woody root, i to xyi feet high (the peduncles); hoary with a dense, 

 soft, and very short pubescence; old leaves silvery white, from 

 nearly reniform to ovate, always with a cuneate base, and with a 

 very long and margined petiole, 3 nerved, cauline none, or a rudi- 

 ment, or occasionally there is a normal leaf at the base of the 

 peduncle, blade 2 inches wide (usually), and an inch long, obtuse and 

 entire; leaves very many and crowded at the root; petioles 5 inches 

 or less long; bracts lanceolate acuminate from a broad base, either
