NATURAL SCIENCES OF PHILADELPHIA. 57 



var. reptans. 19. R. An ambiguous little plant from the alpine region, which 

 might be mistaken for a smaller form of Parry's 79.* 20. Myosurus mini- 

 mus, L., from South Park, with somewhat more of a beak to the achenia than 

 in Eastern or European specimens. 21. Caltha leptosepala, DC. 22. 

 Tkolluts laxits, Salisb. var. Albiftorus, Gray, in Sill. Jour. 33 ; well-developed 

 specimens. Divisions of the leaves less deeply incised than in the Eastern 

 U. S. plant. 23. Aquilegia vulgaris, var. brevistyla. 24. A. ccerulea, Torr., 

 equally beautiful with the specimens of last year. 25. Delphinium elatpm, 

 L., var., Parry's No. 84. 26. D. scopulorum, Gray. 27. A high alpine form 

 of the last. 28. D. Menziesii, DC. ; but if collected east of the Mississippi 

 might be taken for D. tricorne. 29. Aconitum nasutcm, Fisch. ; white and 

 blue, as in Parry's 86. 



BERBEPJDACEyE. 



30. Berberis (Mahonia) Aquifolium, Pursh, var. rep ens. 



FUMARIACEJE.t 



31. Corydalis aurea, Willd., var. curvisiliqca ( C. curvlsillqua, Engelm.), 

 the same as Wright's No. 1309. 



CRUCIFER2E. 



32. Nasturtium obtusum, Nutt. 33. Cardamine hiksuta, L. 34. C. cordi- 

 folia, Gray.J 35. Streptanthus angustifolius, Nutt. ; probably a form of 

 S. sagittatus, Nutt. 36. Turritis patula, Graham. 37. Sisymbrium virgatum, 

 Nutt., but from the silique rather an Erysimum. 38. Erysimum cheiranthoides, 

 L. 39. E. pumilum, Nutt., (which I suppose is also E. lanceolatum, R. Br., of 

 the Old World,) as to the fruiting alpine specimens, along with forms of E. 

 asperum, DC, with large .flowers (E. Arkccnsahum). The collectors think 

 these are all forms of one species. 40. Sysimbrium Sophia, L. (including S. 

 caaescens, Nutt.), both asmoothish form, with short pedicels and short pods, 

 (<S. brachycafpum, Richards.), and also with slender pods, and the whole 

 herbage viscid with glandular pubescence one of the forms of S. incision, 

 Engeltn. 41. Draba crassifolia, Graham ; which, in Parry's former collec- 

 tion, No. 93, I named Draba Johannis, but it proves to have yellow flowers. 

 With it is mixed a very little D. stellata, var. fiebecarpa, as the species are 



silari parva adnata ; acheniis in capitulum ovale digestis Isevibus turgi.lis, rostro longiuseulo en- 

 sifornu utrin'que scarioso-alato ! In the high alpine region, close to the snow. Dr. Parry's speci- 

 mens of 1862, collected later in the season, with some mature fruit, and with some of the stems 

 becoming procumbent or runner-like, and producing a flowering shoot from the axils of the can- 

 line leaves, enable me to characterize this remarkable species. Iu the early state it bears some 

 resemblance to Adonis vernalis. The scarious wingsof the style are sometimes decurrent on the 

 acheuium, which, again, often has a delicate hyaline wing round the base. Notwithstanding the 

 yellow tioweis, the affinity of the species is probably with R. glacialis, the carpel and style of 

 which is said to be wing-margined. The corolla is equally large and full. 



* This. fr. im better specimens collected this year, confirms Mr. Black's opinion that it is a dwarf 

 R: alismiefolius ; but the uppermost leaf is often three parted, and the achenia have a small 

 short beak, and are pub'erulent; the three-parted leaf, the puberulent achenia and too large fl >wcr 

 separate it from R. FlauirmUaveir. reptans: and the mostly entire and narrow leaves, the globular 

 head of carpels and the depauperate size (2 or 3 inches) from R. ujjinis, of which it has the 

 achenia. 1 have seen only a single specimen. 



f- Papaver alpinum, L., was again collected by Dr. Parry, No. 147. 



J This sp-eies whieh h .Ids itscharacters well when described, was compared with ourC. rhnm- 

 boidea and rotwudifolia on the one hand, and on the other, with the European C.asori folia, which, 

 so far as recorded, inhabits only central Europe, lsut I have just received from Kew a specimen 

 collected by Dr. Lyall on the banks of the Ashtnoda River, in the Cascade Mountains of N. W. 

 America, at about lat. 4'J", which, so far as my means of comparison extend, appears to belong to 



C. asartfoiia. The interesting bearing upon questions of geographical distribution ia obvious, 



viz.: as to the probable affiliation of C. asarifolia, anguluta, cordifolia, rhumboidea and rotiindi- 

 folia . 



g Specimens of this were sent by me to Dr. Hooker, to ask his opinion. He replies : " It is Dra- 

 ba Johannis of Europe, according to Mr. Ball, except that the flower is yellow. It is certainly also 



D. crassifolia, Graham, from Rocky Mountains, Drummond, and evidently the same as D.l\ad- 

 nitzensis, Walp., and D. lactea, Adams, B.pygmsea, Turcz., and a host of others."
