stems of this curious dwarf species are czspitose from a branched and tortuous caudex. 
The corolla, which is at first yellow, appears to turn purple in fading. 
134. PeraLosremon vittosum, Nutt. Gen. 2. p. 85; Torr. § Gray, Fl. 1. p. 310. 
Sandy soil, between the crossing of the Cimarron and the Middle Spring ; August. 
135. P. cractte, Nutt. in Jour. Acad. Philad.7. p.92. Santa Fé; on the Cimar- 
ron; and west of Independence, Missouri. — Some of the specimens, I know not from 
which locality, have awn-pointed or cuspidate bracts, which are longer than the flower- 
buds, and are scarcely, if at all, distinguishable from P. candidum, to which the whole 
_ species is perhaps too closely related. 
+136. P. canpipum, Micha. Fl. 2. p. 49. t. 37. f. 1. Prairies, near the upper ferry 
of the Kansas River. 
+137. P. viocaceum, Michx. Fl. 2. p. 50, t. 37. f2:—a pubescent variety; the calyx 
very silky-villous. Five miles west of Las Vegas, New Mexico ; August. 
138. P. vioraceum, Michz.:—a more slender glabrous form, with shorter points 
to the bracts; otherwise nearly as the last. Between Willow Bar and Middle Spring, 
Cimarron, in sandy soil. 
+139. .P. macrostacnyum, Torr. in Ann. Lyc. New York, 2. p.176; Torr. § Gray, 
Fi. l. c. A single specimen, with white flowers (those of P. ornatum, Dougl. are 
violet). Prairie, 18 miles west of Lower Spring, Cimarron; August.*

Hartw. no. 50; non Torr. §- Gray. Poti Creek, between Bent’s Fort and Santa Fé, 
and on Santa Fé Creek, near the water. — Well distinguished from T. tridentatum, 
Lindl., by the longer calyx-teeth and corolla. The only species of the involucrate sec- 
tion which has been found (now for the first time in so high a latitude) east of the Rocky 
Mountains or the Andez. 
141. Metimotus parvirtora, Desf. Low grounds, around Santa Fé. 
142. Mepicaco sativa, Linn. Fields, around Santa Fé. — This and the last were 
undoubtedly introduced from Europe. From Dr. Gregg’s collections, both appear to be 
naturalized throughout Northern Mexico.
