DeLPHINIuM DEPAUPERATUM, Nutt.—Near base of Mount Whitney (395), 
ht pe Li. 
Aconitum Fiscuert, Reich , (373), i. c. p. 12. 
PAPAVERACEZ. 
DENDROMECON RIGIDUM, Benth—TIsland of Santa Cruz, off Santa Bar- 
bara, growing on rocky hillsides, /. c. p. 22. 
Escuscuottzia Cauirornica, Cham.—Quite abundant near Santa 
Barbara, where it is one of the most characteristic plants (86), J. c. p. 22. 
CRUCIFERA. 
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. J 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) 1. ¢. p. 43. 
NAsTuRTIUM OBTuUSUM, 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), /. ¢. p. 613. 
CarpAMIne GaMBELLI, Watson, /. ¢. p. 30—Not common; found only 
near Santa Barbara. 
SisyMBRIUM CANESCENS, Nutt.—Head of Peru Creek; altitude 5,100 
feet (230), 2. ¢ p. 40. 
*As not entirely irrelevant, I may quote from De Candolle, Géographie Botanique, p. 746, footnote 
(a); Le Nasturtium officinale et le Barbarea vulgaris, par exemple, se trouvent sur la céte nord-ouest, ef 
MM. Torrey et Gray les regardent comme introduits dans les anciens Etats de ’Union. II est possible 
qu’jJs soient venus d’Europe, mais ils peuvent aussi étre venus d’ailleurs, ou avoir été primitivement 
plus repandus en Amérique.”
