RECENT BOTANICAL LITERATURE. 43 
California. Remarking that his new Papaver Californicum 
is altogether like the Californian Meconopsis, except in its 
pod, the author says that the former may suggest the probable 
genealogy of the latter. It is almost singular that he does 
not here mention a still more remarkable and suggestive 
Papaveraceous discovery made also during the last season, 
and in almost the same region, by the present writer. I refer 
to my Dendromecon flexile, pablished in the Bulletin of the 
Torrey Botanical Club of November, 1886. Of this genus the 
original, and long the only known species, is a common shrub 
of the mountainous parts of central and southern California ; 
and Santa Cruz Island, which lies in view from the Santa 
Inez range, is covered with the very distinct new species, a 
much larger shrub than D. rigidum ; while a third species, 
D. Harfordii, of Dr. Kellogg, is said to be equally prevalent 
on the island of Santa Rosa, which lies closely adjacent to 
Santa Cruz. Are not these insular shrubs really the most in- 
teresting of all American Papaveracew, raising a curious 
question, it may be, of the genealogy of the one mainland 
species of Dendromecon ? 
The one genus of the order which now receives a formal 
elaboration at the hands of Professor Gray is Eschscholtzia. 
In the frst volume of the Botany of California, now eleven 
years in print, only two species were admitted. In a paper 
printed some two years since, in the Bulletin of the California 
Academy, the number was raised to ten. The present mono- 
graph is, in the main, an adoption of the species and the 
arrangement proposed in that paper of two years ago. The 
author would partly exeuse the errors which had been run into 
at Cambridge, by saying that they had not known the typical 
E. Californica to be perennial. The late Dr. Engelmann no 
longer ago than the year 1881 announced in the Botanical 
Gazette what he took to be a new discovery of his, that the 
plant has a perennial root. Weof California had long known 
that; and yet there was no call for us to publish the fact ; 
the discoverer and founder of the genus, Chamisso, himself
