﻿110 PLANTS FENDLERIAN.E. 



f445. Tetradymia inermis, Nutt. ; Torr. fy Gray, FL 2. p. 447. Sunny side of a 

 hill near Santa Fe ; 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. 



446. Cirsium canescens, Nutt. in Trans. Amer. Phil. Soc. (n. ser.) 7. p. 420? 

 Foot of mountains around Santa Fe, 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. 

 S f447. C. ochrocentrum (sp. now) : caule foliosissimo erecto foliisque subtus lanu- 

 gine densa incanis ; foliis pinnatifidis sessilibus summis subdecurrentibus supra arenosis, 

 lobis brevibus saepe bifidis (radicalibus pinnatisectis, pinnis elongato-lanceolatis acumina- 

 tis inciso-pinnatifidis) spinis flavicantibus horridis, capitulis subsolitariis ad apicem ramo- 

 rum foliosorum sessilibus ; involucri globosi squamis glabris in spinam validam flavidam 

 abrupte desinentibus. — Mountain-sides, around Santa Fe ; 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.* 



* The following is from Coulter's Californian collection : — 



Cirsium Coulteri (Harv. <$- Gray, in PI. 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-Ianosissimi laxe imbricatis rectis demum 

 patentibus omnibus e basi brevi lanceolata vel oblonga in appendicem acicularem pralongam 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.
