SALICACEAE. — SALIX 143 
ticulata. Amenta ramulos foliosos terminantia, pleraque brevia et pauciflora; flores 
c? biglandulosi; 9 plerique tantum glandula una ventrali instructa, sed interdum 
biglandulosi; ovaria saepissime glabra, brevipedicellata v. subsessilia, stylo brevi 
stigmatibus bipartitis coronata. 
It seems to me also impossible to separate the sect. Retusae from the sect. Her- 
baceae on account of the serrate or entire leaves or the presence of a second gland in 
the? flowers. As I find and as it is stated by Toepffer (Salicet. Exsiccat. sub No. 27), 
the 9 flowers of S. herbacea Linnaeus usually have only a ventral gland. Even in 
the g' flowers the gland very rarely seems to be “ ringartig, oberwürts unregel- 
missig eingeschnitten," as described by von Seemen.

Specimens collected by P. N. Meyer, Altai, Eemonskai, June 20, 1911 (No. 858; 
G') and Altaisk, June 10, 1911 (No. 820; 9) have rather long, narrow, cylindrical 
catkins, There is a very small dorsal gland in both the sexes. I have not seen a 
Specimen from the northeastern parts of Siberia. This species may have been con- 
fused with S. polaris Wahlenberg and S. rotundifolia Trautvetter, both of which 
have usually entire leaves. See also S. flabellaris Andersson, above.

The types of S. rotundifolia Trautvetter and S. nummularia Andersson were the 
same: A. T. von Middendorff, Maritime Prov., Boganida River, and A. Bunge, 
Altai, “in summis alpibus ad fl. Tschuja.” Whether Andersson’s S. nummularia, 
Var. subretusa (in De Candolle, Prodr. XVI. pt. 2, 298 [1868]) represents a distinct 
variety I do not know. S. rotundifolia Trautvetter is very near S. retusa Linnaeus, 
but the leaves are rounded or cordate at the base and not attenuated and acute.
