is only one of the many varieties of the Linnaean Mimulus luteus, 

 of which species our Herbarium possesses copious specimens from 

 the Pacific side of South and North America (often extending 

 far inland on the mountains), through the whole of the cold and 

 temperate regions of South America, commencing in the Andes 

 of Maule Province in the south, avoiding the tropics, as far as 

 we know, of Peru and Ecuador, but appearing again in Mexico 

 (Orizaba, etc.) and California, and thence extending north through 

 all British Columbia and the islands, to the Russian possessions 

 of Sitka and Unalaskha. It seems to have attained its maxi- 

 mum about the 49th parallel of north latitude, whence Dr. Lyall 

 collected numerous specimens, many quite resembling the Chilian 

 form here represented.
