plants in cultivation, do I discern any distinction in the flow- 

 ers or pods. On the Upper Platte and Canadian, Fremont 

 and Mr. Gordon have gathered specimens in which even the 

 full-grown leaves &c. are silvery-canescent ; namely, var. 

 y. incana: foliis lanceolatis vel ovatis undique argenteo- 

 incanis.

 Philad. 2. p. 118 ; Hook. Bot. Mag. t. 2566 ; Torr. fy Gray, 

 I. c. CE. Roemeriana, Scheele in Linncea, 22. p. 154. Mus- 

 kit flats, New Braunfels. March, April. In cultivation, and 

 I think also in the wild state, this is a biennial. It forms a 

 dense cone of pods at the crown, which rises to the height of 

 two or three inches in the course of the season, and the root 

 does not survive the winter. The flowers, which open about 

 sunset, are cream-colored or nearly white. 



393. CE. (Meriolix) serrulata S. spinulosa, Torr. fy 

 Gray, Fl. 1 . p. 502 ; subvar. floribus, ut in No. 238, maxi- 

 mis, calycis fauce cum stigmate ssepius atropurpurea interdum 

 fusca v. flava. — Rocky banks of the Cibolo River. April. 

 In cultivation, as in the wild plant, the throat of the calyx 

 and the disk-shaped stigma, one or both, are sometimes deep 

 black-purple, sometimes brownish or yellow. The plant 

 forms rather stout and decumbent woody stems, two or three 

 feet long, producing a great number of branches, and flower- 

 ing throughout the summer. 



394. CE. serrulata, e. pinifolia, Engelm. : foliis angus- 

 tissimis fere filiformibus saepe fasciculatis marginibus revolutis 

 integris ; floribus maximis (ut in praecedente). CE. capilli- 

 folia, Scheele in Linncsa, 21. p. 577. Rocky prairies, New 

 Braunfels. April. — This is just the CE. serrulata var. spinu- 

 losa, except that the leaves are extremely narrow. It is vain 

 to attempt to erect the varying forms of this and other poly- 

 morphous CEnotherse into separate species.
