spreading lobes a line long, and usually isliccs stems and leaves; 
it grows 1 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 albicaulis T. & G. This is also B. grave- 
olens var. albicaulis Gray, and will include as varieties of it var. 
latisquama (Gray) and var. hololeuca (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 thatortes 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 value. 
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 
1% to 2% feet high, grows in clumps liké 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 Sarcobatus 
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. 
Flelianthella argophylla (Eaton) Gray. This botanical nomad, — 
which has been successively called Zithonia argophylla, Encelia ar- 
gophylla, Encelia nudicaulis, Helianthella nudicaulis, and now rests 
under the above name as the proper one, is caespitose from a deep 
woody root, 1 to 14 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 
boas long and margined petiole, 3 nerved, cauline none, or a rudi- 
ent, or occasionally there is a normal leaf at the base of the 
ie 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
