The Delphinium here figured was first met with in 
1872 by Przewalski on the Kansu border, on the mountains 
just south of the Tetung River. It was first flowered in 
the Botanic Garden at Petrograd in 1876 from seed 
communicated by Przewalski, and was named _ by 
Maximowicz D. Pylzowii, in honour of Przewalski’s 
travelling companion, M. A. Pylzow. Przewalski gathered 
the species again in 1880 at elevations of 9,000 to 11,000 
feet, between Kuku-Nor and the Tetung, and it has since 
JULY-SEPTEMBER, 1919.
