CRASSULACE^I. 



ISS4 Sedc3I rhodanthtjm, Gray, Enum. PI. Parry. In fruit ; the inflores- 

 cence a dense spike-like thyrsus, oblong. 190. S. stexopetalum, Pursh. 

 191. S. Rhodiola, L. (192. See Borraginacese. 



SAXIFRAGACEiE. 



193. Saxifraga nivalis, var. ? An undeveloped specimen of this, in Parry's 

 collection of 1851, was referred to S. hieracifolia? But the well- developed 

 specimens appear to pass into the large state of the next. The limits between 

 >S. nivalis, Virginiensis and intecjrifolia are not obvious. 194 . S. nivalis, L., 

 one form the same as Parry's 169; the other has a scape nine inches high, 

 bearing several peduncled erect flower-clusters in a racemose manner, just as 

 in 193, from which it differs in its shorter and smaller, more-toothed leaves. 

 195. S. cersua, L. 196. S. controversa, Sternb., referred by several authors 

 toS. ads c end ens, L. Alpine region ; before found in America ofily by Bourgean v 

 in the Rocky Mountains further north ; known in Northern Asia. 197. S. 

 broschialis, L. 198. S. debilis, Engelm. n. sp * "Alpine." 199. S. ser- 

 pyllifolia, Pursh "pbut probably only a high alpine, very dwarf and tufted 

 variety of S. Hir cuius, L., this beinp; the view taken of it in the Enumeration 

 of Parry's collection of 1861, No. 164. The characters holdout in the present 

 collection. 201. S. Httccttlitr. L.. in the ordinarv form 



as possible. ^Sonth Park, in wet or swampy places." 2JXL S. flagellars, 

 Willd. (202. See under Prinmlacese.) 203. S. Jamesii, Torn, from the origi- 

 nal stations. A most rare and peculiar species. 207. S. punctata, L. (& 

 (rstivalis, Fisch.) 204. Heuchera parvifolia, Nutt, the large form,— viz.: 

 Parry's 174, — with some specimens passing to Parry's 173, the small form. 

 205/ Heuchera bracteata,| Seringe (Tiardla? bracteata, Torr.,) the same as 

 Carry's 172, mixed with a large-flowered, apparently new species, H. Hallii.J 

 Rocks, on mountains of medium elevation. 206. Lithopiibagma parvifolia, 

 Nutt. 208. Mitella pentasdra, Hook.; iiTTrtiit. 5JS. Chrysosplenium 

 alterxifolium, L> 568. Jamesia Americana, Torr. & Gray. (209. See Eu- 

 phorbiacese.) 



UMBELLIFEPviE. 



210. Cymopterus glomeratus, DC. A plant rarely collected, but said to 

 be very common on the plains, along with the next. 211. C montanus, Nutt. 

 213, C. alpinus, Gray, Enum. PI. Parry, p. 19 (408, f^o. 158; with good 

 Lruit as well as flowers. 212. Peucedanum nudicaule, Nutt. ? at least the 

 plant so named in Hayd en ^""collection on the Mauvaises Terres of Nebraska ; 

 but the plant is minutely prninose-pubescent, not glabrous, nor is the fruit 

 truly that of a Peucedanum, the marginal wings being double, nor from the 

 description can it be the original Smyrnium nudicaule of Pursh. It must re- 



* This was mixed with No. 167 (S. cermja, L.) of Dr. Parry's collection in 1861, but very spa- 

 ringly distributed. It has a granulate root, so called, and the foliage much 'as in S. Sibirica, but 



550. which in the Flora R - 9. are doubtfully referred to & rivulan's. In which case I know of
