A very handsome species of Corydalis, allied to the 
common (. bulbosa, Linn., of our gardens, but with fewer 
flowers of very much greater size. Dr. de Regel, to whose 
exertions we are indebted for so many beautiful novelties 
from Central Asia, first described it in 1870 from specimens 
collected by Semenov in 1857, in the cis- and trans-Ili 
provinces of Western Turkestan; and he afterwards 
figured it in his Garden Flora, from plants which flowered 
in the St. Petersburg Garden, and of which roots were 
sent by his indefatigable and intrepid son, Dr. Albert Regel. 
As a species he regards it as nearest to C. Ledebouriana, 
Karel. and Kiril., of Soongaria (which in the “ Flora 
Indica,” but not in the Flora of British India, was 
erroneously referred to OC. rutefolia), and indeed it much 
resembles a greatly enlarged form of that plant. _ ; 
C. Sewerzovi was drawn from specimens sent to Kew 
by Mr. Elwes, from his garden at Preston, Cirencester, in 
February last, where it had flowered in a frame under 
protection. It flowered at the same time at Kew, from 
tubers, received in June, 1885, from Dr. Aitchison, botanist 
to the Affghanistan Boundary Commission.
