NORTHEASTERN ASIA. Transbaikalia to Kamtchatka. 
According to Rydberg (in Bull. N. York Bot. Gard. I. 260 [1899]), the true S. 
reticulata is absent from North America, and S. vestita Pursh (Fl. Am. Sept. Il. 
610 [1814]) does not occur in Asia. The specimens mentioned by Herder, l. c. 451, 
as S. reticulata, var. sericea Andersson belong to S. reticulata Linnaeus and not to 
S. vestita Pursh, which differs in its shorter-stalked leaves with a persistent silky 
pubescence on the lower surface. The petioles are only about as long as the buds. 
Sect. 22. LINDLEYANAE Schneider, n. sect. 
Salix, sect. Nitidulae, a. Myrtosaliz Andersson in De Candolle, Prodr. XVI. 
pt. 2, 285 (1868) et b. Retusae Andersson, l. c. 293 (pro parte). 
Fruticuli pygmaei habitu iis sect. Herbaceae. Folia parva v. minima, pleraque 
lanceolata, oblanceolata v. ovato-lanceolata, integra v. serrata v. lobulato-incisa, 
supra viridia, nervis plus minusve impressis v. enervia, subtus discoloria, pallida v. 
glauca v. pallide viridia, costa nervisque elevatis v. enervia. Amenta ramulos 
foliolatos terminantia, pleraque brevia et pauciflora; flores c" diandri, antheris 
(an semper) flavis, glandulis duobus; flores 9 glandula pleraque unica ventrali; 
ovaria glabra, brevipedicellate, stylo brevi v. mediocri apice bifido, stigmatibus 
ipartitis. 
This section is apparently nearly related to sect. Herbaceae, but differs in the 
leaves, which are paler below and have a different venation. 'The geographical 
distribution of the species is also entirely different; the Himalaya and the high 
mountains of western China being regions where no species of sect. Her- 
baceae occurs.
