7 445.. Tetrapymia wermis, Nuit.; Torr. & Gray, Fl. 2. p. 447. Sunny side of a 
hill near Santa Fé; July. A shrub three feet high ; only a single shrub was met with. 
— T. canescens, DC., to which the above species too nearly approaches, is also shrubby, 
as is shown by specimens sent by Mr. Spalding from Kooskooskee River.

Foot of mountains around Santa Fé, on the sunny side; May, June. (485.)— The 
specimens are fully two feet high, clothed with floccose white wool, with the leaves de- 
current into rather prolonged but narrow and very spiny wings. Heads smaller than in 
C. undulatum ; the flowers apparently ochroleucous. 4.5». 6 ©... Whisy co 
_ 7447. C. ocurocentrum (sp. nov.): caule foliosissimo erecto foliisque subtus lanu- 
gine densa incanis ; foliis pinnatifidis sessilibus summis subdecurrentibus supra arenosis, 
lobis brevibus sepe bifidis (radicalibus pinnatisectis, pinnis elongato-lanceolatis acumina- 
tis inciso-pinnatifidis) spinis flavicantibus horridis, capitulis subsolitariis ad apicem ramo- 
tum foliosorum sessilibus ; involucri globosi squamis glabris in spinam validam flavidam 
abrupte desinentibus. — Mountain-sides, around Santa Fé; July. (486.) — The radical 
leaves are described from specimens of what I take to be the same species, although 
there are no flowering stems, gathered by Dr. Gregg in the valley of Saltillo, in 
March, That plant is said to attain three feet in height. Fendler’s specimen is only a 
foot high, with the cauline leaves from 4 to 6 inches long, white, and very spiny; the 
longer spines and still stouter ones which tip the scales of the involucre half an inch in 
length and yellowish (whence the specific name). Heads rather small, less than an inch 
in diameter. Corolla apparently pale-purple.* pr0O#®, & Je LOC yn, A 
* The following is from Coulter’s Californian collection : — 
Cirsium Counter (Harv. § Gray, in Pl. Coult. ined.) : arachnoideo-tomentosum; caule ramoso; foliis 
caulinis oblongo-lanceolatis subamplexicaulibus undulatis sinuatis spinescentibus supra laxe arachnoideis ; capi- 
tulis maximis ebracteatis solitariis ; squamis involucri arachnoideo-lanosissimi laxe imbricatis rectis demum 
patentibus omnibus e basi brevi lanceolata vel oblonga in appendicem acicularem prelongam apice cuspidatam 
sensim attenuatis. — California, Coulter. — Mature heads nearly two inches in diameter. Scales of the invo- 
lucre all similar, but the inner successively longer; the slender and spine-like filiform appendages thrice the 
length of the dilated portion ; the innermost as long as the (purple?) flowers; the outermost much shorter 
and at length reflexed. Filaments hairy.
