ter superantibus demum papyraceis cum achenio delapsis vel tardissime articulo secedentibus ; receptaculo 
convexo ; acheniis tetraquetris apicem versus pubescentioribus prismaticis, radii modice obcompressis. — Sandy 
plains, Clear Water, on the Kooskooskee, Oregon, Rev. Mr. Spalding ; flowering in May. — Root apparently 
thick, as in the genuine species of Balsamorrhiza. Stem from 6 to 14 inches high. Radical leaves 3 or 4, 
or when mature 6, inches long ; the cauline 2 or 3; the petiole as long as the blade. Lateral heads on slen- 
der peduncles. Inyolucre half or three fourths of an inch in diameter. Rays nearly an inch long, when old 
apparently light yellow, raised on a short tube, the base of which is articulated with the very obtuse summit 
of the achenium, but is persistent until the fruit is fully ripe. Disk-corolla, style, &c., as in Balsamorrhiza. 
— This interesting species is dedicated to my friend Mr. John Carey, who pointed out to me its characters 
and affinities. Mr. Spalding’s collection likewise contains the following genuine species of this characteristic 
Oregon genus, viz. : — 
B. sacirrata, Nutt. Called by the natives “* Pash. The tender stalks, the root, and the seeds, used for 
food.” This circumstance, the habitat, and the involucre, the exterior scales of which are longer than the 
others and exceed the disk, render it sure that this plant is the Buphthalmum sagittatum of Pursh ; but an im- 
perfect authentic specimen of Bals. helianthoides, Nutt., does not show any marked difference. The heads in 
Mr. Spalding’s specimens are fully four inches broad, including the extended rays. The small cauline leaves 
are alternate. 
B. wncana, Nutt. Called “ Isilil. The root, like Kayum, exudes a resinous juice: used for food when 
peeled and baked.” Some of the leaves are pinnately parted ; others only incised. 
B. teresinTHacea (Hook.): scabro-pubescens, foliis radicalibus ovato-lanceolatis oblongisve basi trunca- 
tis vel obtusis sinuato-pinnatifidis seu integris dentatis, caulinis 2 oppositis juxta basin scapi (5-12 unc. longi) 
monocephali lanceolatis spe pectinato-incisis; involucro hirsuti-tomentoso pluriseriali, squamis lanceolatis 
attenuatis disco sublongioribus. — Heliopsis ? (Balsamorrhiza) terebinthacea, Hook. Fl. Bor.-Am. 1. p. 310. 
—‘“ Kayum. High, hard land. The bark of the root gives a turpentine, like that of pine in taste and smell. 
Root peeled and baked for food.” — This is certainly distinct from B. Hookeri, 8. Torr. §& Gray, Fl. 1. c., to 
which the synonyme was doubtfully referred; and is more like B. hirsuta, Nutt., but has larger and more 
woolly heads, and more attenuated involucral scales, as well as undivided or slightly pinnatifid leaves. The 
foliage, however, is extremely variable in this genus. The form which, among Mr. Spalding’s specimens, best 
accords with Hooker’s brief character, has almost undivided leaves, which are beset with very sharp and 
strong salient teeth. A larger variety has the radical leaves a foot long, including the petiole, and barely 
crenate-serrate. Involucre fully an inch in diameter. Receptacle convex. The root very thick and long. 
WYETHIA HELENIOIDES, viz. the Alargonia helenioides, DC., a species totally distinct from W. robusta or 
any other in the Flora of N. America, and with the fruitful head three inches in diameter, occurs in the Califor- 
nian collection made by Fremont in 1846. The achenia, with the calyciform pappus, is over half an inch long. 
The older leaves (the radical even four inches wide) are glabrous; but those of the same species in Hart- 
weg’s collection, gathered in an earlier state, are floccose-tomentose. (I suspect that the W. ovata, briefly 
characterized by Dr. Torrey in Emory’s Report, will prove to be the same species. )
