Meconopsis heterophylla is the sole American representa- 
tive, as M. cambrica is the sole European, of a genus which 
is well represented only in the loftier Himalaya and the 
mountains of W.China. Both the European and American 
species are of very limited range, the former to Wales, 
Ireland, and the Pyrenees, the latter to a very few 
localities in W. America, from Clear Lake, in lat. 42° N. to 
San Quintin Bay in the California Peninsula, lat. 303° N. 
It also inhabits the Humboldt range in W. Nevada. As 
might be anticipated from the remoteness of its native 
country from those of its Old World congeners, and 
especially from its inhabiting so much hotter and drier a 
climate than these do, it exhibits some structural pecu- 
liarities. Such are the pinnatipartite foliage, the re- 
markable elongate obconical truncate smooth capsule, and 
smooth, orbicular seeds. 
David Douglas was the discoverer of M. heterophylla, 
during his journey across the continent of N. America in 
1833. Though covering so wide a range of latitude it 
cannot be a common plant, few collectors having met with 
January Ist, 1899. ce 3
