So far as I can judge from the material before me these forms of S. Caprea from 
eastern Asia may represent a somewhat different form or include some hybri 
Von Seemen (in Ascherson & Graebner, Syn. Mitteleur. Fl. IV. 101 [1909], de- 
scribes S. Caprea, var. villosa with roundish, entire, tomentose leaves and tomen- 
tose branchlets from eastern Asia, collected by Siuzev. Nakai does not mention 
S. Caprea from Korea; he cites S. cinerea Linnaeus (see above), but Léveillé (in 
Fedde, Rep. Spec. Nov. X. 435 [1912]) describes a S. hallaisanensis with a vat. 
nervosa from Korea, Quelpaert, “ in sylvis Hallaisan,” circ. 1200 m., June 9, 1908, 
Taquet (No. 1442; almost creeping shrub, 0.6-0.7 m. tall; with fruits; No. 1443); 
same locality, alt. 1200 m., August 12, 1908, Taquet (No. 1444, type of var. 
nervosa, sterile); same place, alt. 1200 m., June 1909, Taquet (Nos. 3251, 3252, 
3253, 3255, 3256, 3258, 3259, 3260, 9 co-types, 3257, c^ co-type); ^in Monte des 
Diamants,” June 20, 1906, U. Faurie (No. 174; 9), “in aridis montium Quelpaert, 
supra 1200 m.,” July 1907, U. Faurie (No. 1502; 1 m. alta; 9); Hallaisan, alt. 1300- 
m., October, 1907, U. Faurie (No. 324; sterile). All these specimens have orbicular- 
ovate, entire or crenate leaves, prominently reticulate beneath. There seems to 
no real difference between these and S. Caprea, the older branchlets being glabrous, 
not hairy as in S. cinerea. See also S. Wallichiana Andersson, p. 64. __ 
In the northwestern Himalaya S. Caprea is only cultivated. See Brandis (Forest 
F ien Ind. 467, t. 60 [1874]; the 9 flower on the plate shows a very short 
pedicel. 
According to von Seemen (apud Siuzev in Trav. Mus. Bot. Acad. Sci. St. Péters- 
bourg, IX. No. 2 [1912] ex Toepffer, Salicol. Mitt. No. 5, 248 [1912]), also S. auria 
Linnaeus has been found in Mandshuria. All the species of sect. Capreae are very 
closely related, and they need a special and careful study.

The author has kindly sent me a male catkin of this species. This is 2.2 cm. long 
and about 1.3 em. thick, subsessile, the peduncle being only about 5 mm. long, 
bearing two small leaves, which are glabrous above and a little silky beneath. The 
flowers have a short and rather broad flat ventral gland, 4 or 5 times shorter than
