PAPAVERACE^. 
16. Papaver nudicaule, Linn., Hook. Fl. Bor. Amer. vol. i. p. 34.— Torr. et Gray, Fl. of N. 
Amer. vol. i. p. 60. Common tbroughout Western Eskimaux-land. It bas also been found between 
Point Barrow and Mackenzie River {Pullen), in Bucban and Comwallis Islands [Ede], and in Assist- 
ance Bay [Penny), 
P. nudicaule alters tbe colour of its petals, of wliicb apparently temperature is the cause. In Kotzebue 
Sound and other subarctic parts the petals are yeUow ; towards Point Barrow, and in exposed positions, 
almost invariably white. In another JPapaveracea I noticed a siniikr change. Argemone Mexicana, Lmn., 
is around Lima and the temperate districts of Ecuador, white; in the torrid regions of New Granada, Central 
America, Mexico, and AAica, yellow; while, at the Hawaiian Islands, which enjoy a cool chmate, the colour 
is again changed into white. 
FUMARIACE.E. 
Amer, 
Amer. vol. i. p. 70. Island of St. Lawrence. 
The idand of St. Lawrence seems to be the most northern limit which this species attains ; the 
specimens contained in Herbaria have exclusively been gathered there and in Siberia none on t^o '"-^^'^l 
of America. The Corydalis pauoiJU>ra appears, therefore, to have its focus m Asia rather than m America.
