a very minute apiculate cone. On the other hand, the conical appendage is manifest in 
some of the Eriophylla, as in B. leucophylla. If the two genera are to be restored, they 
must bear the names originally imposed by Lagasca. Eriophyllum trolliifolium, Lag., 
which is yet to be identified, is certainly of a different genus.* 
» 421. ActinriLa arceNTea (sp. nov.) : caulescens, undique sericeo-incana ; caulibus 
(4-10-uncialibus) inferne ramosis adscendentibus apice longe aphyllo monocephalis ; 
foliis integerrimis oblanceolatis nitento-sericeis, imis rosulatis spathulatis 3-nerviis, caulinis 
_ superioribus linearibus uninerviis; involucri squamis 3-seriatis lanceolatis; pappi paleis 
lato-ovatis breviter aristatis, nervo evanido. — Gravelly and stony hills, around Santa 
Fé; April to June. (457.)— This showy species most resembles A. acaulis; but is 
larger, and apparently does not grow in dense tufts; the branching stems are leafy to the 
- middle, and the silky pubescence of the leaves is closer and more silvery. ‘The larger 
specimens are ten inches high; and the stems apparently continue to produce flowering 
branches through the summer. The heads, with the expanded rays, are fully an inch 
and a half in diameter. Ligules 15, cuneate, half an inch long. Receptacle hemi- 
spherical. The silky achenia and the pappus are silvery-white ; the latter of broader 
paleze with shorter awns than in A. acaulis. — The latter was gathered by Dr. Wislizenus 
between Rabbit’s Ear and Rock Creeks ; and Dr. Gregg found at Buena Vista an allied 
species with narrower and glabrate leaves, which I take to be a taller form of A. Tor- 
reyana.t 
* Bahia arachnoidea, Fisch. § Lallem. in Ind. Sem. Hort. Petrop. 1842, remarkable for its dilated rhom- 
bic“or cuneiform and barely lobed leaves, and for a very short pappus, was also gathered at San Francisco, 
California, by the U. S. Exploring Expedition. B. latifolia, Benth. Voy. Sulph. p. 30, from Bodegas, would 
appear to be the same species, with more lobed leaves; but the short palez of the pappus are more than four 
in our plant, and the heads are smaller than those of Bahia lanata. 
; + Two species have been added to this genus by Fremont, viz. the A. grandiflora, Torr. § Gray, in 
Bost. Jour. Nat. Hist., collected in his first expedition, which has pinnately-parted simple leaves, and leafy 
stems, bearing a head nearly as large as that of Gaillardia aristata; and the following : — 
Actinetta pepressa (Torr. §& Gray, Fl. ined.): nana, escaposa, multiceps, caudicibus dense czspitosis 
oblongis foliis anguste linearibus punctatis glabratis basi vaginata imbricante lanatissimis suffultis capitulo 
arcte sessili terminatis; pappi paleis 5-6 ovatis acuminato-aristatis corolla disci paulo brevioribus. — Rocky 
Mountains, apparently at a great elevation, the locality unknown, Col. Fremont; collected in the second 
expedition. The thick, matted stems are only an inch high; and the heads, which are nearly as large as 
of A. acaulis, are strictly sessile and immersed among the very woolly bases of the leaves. Rays 
yellow. Palez of the pappus more or less thickened along the axis. 
Var. 8. PYcm#A: caudicibus cum capitulo globulosis; foliis junioribus cano-sericeis, annotinis glabratis.
