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. 



RANUNCULACEiE. 



1. Atragene alpina, L. 2. Clematis Douglasii, Hook. 3. C. ligustici- 

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

 properly referred to P. patens, and especially by Regel 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. Caroliniana, Walt. ; on the plains. 

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

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

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

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

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

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

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

 var. nutans, C. A. Mey. " 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. Purshii var. repens, 

 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. 13. 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- 

 withstandingthenervose achenia. f 14. R. Eschscholtzii, Schlecht., Hook.; same 

 as the broader-leaved specimens of Parry's No. 80 ; 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. leiocarpus, 

 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. auricomusii 

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

 draceous head. 16. R. affinis. var. cardiophyllus. (R. 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. adoxeus, n. sp.,J No. 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. 18. R. flammitla, L., 



* Dr. Kegel's note under this species, in his elaborate revision of Tliatictrum, is founded on a 

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

 tion, Hook., -non DC. The Candolleau species is wholly different, and a native only of the moun- 

 tains of Carolina.
