CATALOGUE. 73 
TAaLInuM auRANTIACUM, Engelm., var. anGusTIssIMuM, Gray.—Similar 
to the above, except that the leaves are linear, the articulation of the 
peduncle often nearer the axil, sepals approaching the orange color of the 
corolla, and the plant usually lower, averaging 8’ in height. (538.) Rocky 
ledges at Chiricahua Agency, Arizona. 
Tatinum pATENs, Willd.?—1-2° high, glaucous; leaves broadly lanceo- 
late, thin, entire; flowers purple, in bud twice longer than the obtuse 
sepals; inflorescence loose, panicled along the slender branches; seeds not 
mature enough to certainly identify the specimen. (522.) Chiricahua 
Agency, Arizona, on rocky ledges, along with 7. auwrantiacum var. angus- 
tissimum. 
CaLanDRINIA* pyamMaA, Gray (Proc. Am. Acad. viii, p. 623).  (Tali- 
num pygmeum, Gray.)—Colorado. (73.) 
CiayToniaA arTica, Adams, var. MEGARHIZA, Gray.—High mountains 
of Colorado; strictly alpine. The large root penetrates a foot or more 
among the rocks. (74.) 
Craytonia Cuamissonis, Esch. & Ledeb.—Seeds evenly and beautifully 
roughened with minute scale-like markings. I find no allusion under 
description of this species to the markings of the seed, nor have I any ripe 
seed in other authentically determined specimens of the species, but in all 
the other characteristics my plant is so like the broader-leaved form, 
No. 84, of Hall and Harbour, that I cannot doubt the specific identity of 
the two. (219.) Willow Spring, Ariz.; altitude, 7,195 feet. Found 
growing luxuriantly in spring water the temperature of which was 52° 
Fahrenheit. 
Cuaytonta Caro.iniANna, Michx., var SEssILIFOLIA, Torr. (C. lanceolata, 
Pursh.)—Nevada. 7 
Lewisia REDIVIVA, Pursh.—Nevada. 
ELATINEZ. 
Exatine Americana, Arn.—Twin Lakes, San Luis Valley, and Rio 
Grande at Loma, Colo. (775, 776.) 
*CaLanpriniA, H, B. K.—Differs from Talinum, Adans., chiefly in having persistent sepals and 
estrophiolate seeds. :
