APPENDIX. 355 



Delphinium depauperatum, Nutt. — Near base of Mount Whitney (395), 

 I c. p. 11. 



Aconitum Fischeri, Reich., (373), I. c. p. 12. 



PAPAVERACE^B. 



Dendromecon rigidum, Benth. — Island of Santa Cruz, off Santa Bar- 

 bara, growing on rocky hillsides, I. c. p. 22. 



Eschscholtzia Californica, Cham. — Quite abundant near Santa

CRUCIFEILE. 



Nasturtium officinale, R. Br. — I found it, in 1875, in the Coast 

 Range, in places where it is almost impossible to believe it had been intro- 

 duced. So general is the conviction that it is not indigenous, that I hesitate 

 to offer my opinion that it is a native, at least, in some places where now 

 found. I can understand that once introduced into a stream, it may be 

 transported by the current to any distance; but throwing out the agency of 

 birds and similar means of transportation, as entirely inadequate to account 

 for its distribution, I cannot comprehend how it should now be found so 

 frequently at the very fountain head of some streams in places so remote 

 and inaccessible as to have only recently been visited by whites.* Found 

 also at Elizabeth Lake, where it may have been introduced (188) I c. p. 43- 



Nasturtium obtusum, Nutt., var. alpinum, S. Watson. — South Fork of 

 Kern River, at 8,200 feet altitude. I think Mr. Watson correct in regard- 

 ing this a mere variety. From the limited material at my command, I infer, 

 however, that its characters are tolerably constant, especially the relative 

 length of pedicels and pods (322), I. c. p. 613. 



Cardamine Gambellii, Watson, I. c. p. 30. — Not common; found only 

 near Santa Barbara. 



Sisymbrium canescens, Nutt. — Head of Peru Creek; altitude 5,100 

 feet (230), I. c p. 40. 



*As not entirely irrelevant, I may qnote from De Candolle, Geographic Botanique, p. 746, footnote 

 (a): "Le Nasturtium officinale et le Barltarea vulgaris, par exemple, ee trouveut sur la cote nord-ouest, et 

 MM. Torrey et Gray lea regardent comme introduits dans les ancienB Erats de l'Union. II est possible 

 qu'ils soient venus d'Europe, mais ils peuvent aussi etre vouus d'aillenrB, ou avoir e'te' primitivemeut 

 plus repandus en Am^rique."
