SALIC ACE AE. — SALIX 143 



ticulata. Amenta ramulos foliosos terminantia, pleraque brevia et pauciflora; flores 

 cf biglandulosi; 9 plerique tantum glandula una ventrali instructa, ecd interdura 

 biglandulosi; ovaria sacpissime 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 

 the9 flowers. As I find and as it is stated byToepffer (Salicet. Exsiccat. sub No. 27), 

 the 9 flowers of S. herbacea Linnaeus usually have only a ventral gland. Even in 

 the d^ flowers the gland very rarely seems to be " ringartig, oberwarts unregel- 

 massig eingeschnitten," as described by von Seemen.

NORTHEASTERN ASIA. Transbaikalia to the Maritime Prov. (ex 

 Herder). 



Specimens collected by F. N. Meyer, Altai, Eemonskai, June 20, 1911 (No. 858; 

 cf ) 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.

NORTHEASTERN ASIA. Arctic Siberia: Behrmg Straits, Arakam Island, 

 C. Wright, 1853-6. 



The types of S. rotundifolia Trautvetter and S. nummularia Andersson were the 

 same: A. T. von Middcndorff, 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.
