Western Szech’uan: near Monkong Ting, alt. 2600-3000 m., 
side of river, June 29, 1908 (No. 2146, type; bush 3-4.5 m. tall; 9; 
No. 2146*, 9); round Sungpan Ting, bed and banks of Min River, 
alt. 2300-3200 m., August 1910 (No. 4576; bush 3-5 m. tall; sterile). 
At first sight this species much resembles S. Wilhelmsiana M. von Bieberstein 
(see p. 169), but so far as I can judge from the material before me it differs from 
that species chiefly in the very small stigmas and in the mostly two-colored bracts. — 
The very thin c^ catkins are borne on rather long peduncles, and the fruiting 
aments are very short. The value of the color of the bracts needs further in- - $ 
vestigation, because they are partly of one color in Wilson’s specimen. i| 
Withelmsiana, S. microstachya "Turezaninow and their relatives seem to form a 
rather distinct group of the sect. Purpureae, but all the species are very nearly 
related, and there may occur forms like S. cheilophila, which seem to conneet 
these species with S. purpurea Linnaeus and its allies. 
The specific name is derived from xeXos, bank of a river, and $iAéo, I love.

A comparison of the original descriptions of Franchet and von Seemen leaves little 
~~ that the two species are the same. Even the “ ramulos saepius elongates. 
of the 9 catkins measure only up to 1.5 cm. according to Franchet, while 10 
Henry's No. 7175 several peduncles are 2 em. long. The bracts of the 9 flowers 
are described as “ lanceolatae acutiusculae” by Franchet. The arrangement of
