under the same number ; which, under the circumstances, it was not easy 

 altogether to avoid. The collectors appear to have been somewhat too fear- 

 ful of distributing the same species under two or more numbers ; but the op- 

 posite course, in case of doubt, is preferable. Even well-marked varieties 

 had better be kept separate in distributed collections. 



ENUMERATION. 



. RANUNCULACEJE. 



1. Atragene alpina, L. 2. Clematis Douglastt, Hook. 3. C. LiGtrsnci- 

 folia, Nutt. 4. Pulsatilla Ncttalliana, Gray, which I am now convinced is 

 properly referred to P. patens, and especially by Kegel to his var. Wolfgangi- 

 ana. Some of the specimens are very large and fine. 5. Anemone multifida, 

 DC., both red and white-flowered. 6^ A. CAROLmAffA,TValt. ; on the plains. 

 7. A. sarcissiflora, L., from the alpine region ; not before known this side 

 o? Russian America ; fine specimens, with the flowers only three, two, or one 

 to the involucre. 8. Thalictrum Fejtoleri, Engelm. ; the diagnosis noted in 

 the Enum. PL Parry*" p. 12, and now the species itself is obtained, tl on low 

 mountains." 9. T. sparsiflorum, Turez.,* in fruit, k ' the whole plant with a 

 very heavy narcotic odor," according to Dr. Parry. 10. T. alfixum, L., large 

 specimens. 11. Ranunculus Cymbalabia, Pursh. 12. R. hyperboreus, Rottb. 

 var. natanSf C. A. Mey. M In water or in swamps, at middle elevations in the 

 mountains, or subalpine ;" from the station and from the size of the plants 

 so much approaching the small and emersed form of R. Purskii var. rcpens, 

 Hook., (R. Gmelini, DC, of which a few specimens were also collected,) that 

 it might belong to that species except for the want of a style ; mature fruit not 

 collected. J£. R. (Cyrtorrhyncha) Nuttallii, the very rare Cyrtorrhyncha ranun- 

 culina, Nutt. in Torr. and Gray FL, which is rightly determined by Bentham 

 and Hooker to have the ovule erect, and therefore to be a Ranunculus, not- 

 withstanding the nervoseachenia.f 14. R. Kschscholtzii, Schlecht., Hook. ; same 

 as the broader-leaved specimens ofTarry's No. SO ; has glabrous peduncles, 

 smaller flowers, and shorter styles than R. nivalis, but Greenland specimens 

 of Vahl's collection approach it. 15. R. affinis, R. Br. var. leiocarptts, 

 Trautv. : the same as narrow-leaved specimens mixed last year with Dr. 

 Parry's No. 80 (vide Sill. Jour., 33, p. 404) ; may be a form of R. auricomus if 

 that ever has glabrous achenia, but they compose a rather oblong or cylin- 

 draceous head. 16. R. affiitis, var. cardiophyllus. (i?. cardiopkyllus, Hook.) 

 The flowering specimens, with their cordate-rotund radical leaves, villous pu- 

 bescence and large flowers (the corolla a full inch in diameter) perfectly ac- 

 cord with Hooker's figure, except that the stature is dwarf, and the young carpels 

 show a rather long style, as figured; but accompanying fruiting specimens wholly 

 accord with R. affinis. 17. R. adoseus, n. sp.,J Ps T o. 81, of last year's collection 

 of Dr. Parry, who has now supplied the fruit ; and the species proves to be a 

 new and peculiar, handsome and strictly alpine one.§ 13. R. flammula, L., 



* Dr. Kepi's note under this specie, in his elaborate revision of Thalictrum, is founded on a 

 misreading of my foot-note in PI. Wright, 2, p. 8, where to T. sparsiflorum is referred T. clara- 

 turn, Hook-, non DC. The Candollean spacies id whully different, and a native only of the moun-
