SALIX 
MM. Camus (op. cit .) base their subgeneric divisions of Salix largely on anatomical characters. These authors first 
divide Salix into two main groups. The first of these is characterized by the presence of stomata on the upper surface of 
the lamina, the second by the absence of such stomata. S. herbacea is placed in the first of these groups, and S. reticulata 
in the second. In our judgment, such a classification, though very interesting, is both unnatural and impracticable. 
MM. Camus claim (op. cit. p. 13) that the classification they have adopted is based on the sum of the morphological 
and anatomical characters of the genus ; but it may be doubted if they have correctly assessed the relative values of 
these characters. 
Only British species : — S. reticulata.

Dwarf undershrub. Rhizome branched, short. Aerial stem procumbent or a little ascending, 
much branched. Buds oval. Stipules caducous, glandular. Petioles 
long, usually reddish in colour. Laminae suborbicular to broadly 
oval or oboval, up to about 3-0 cm. long, and 2 '5 cm. broad, entire 
or finely glandular serrate, thick, upper surface rugose and dark 
green, lower surface subglaucous or greyish and reticulated with 
prominent veins, sometimes more or less silky when young. 
Catkins narrowly cylindrical, about 1*5 — 3‘ocm. long and 3'0 mm, 
broad, on leafless peduncles of about the same length, appearing 
with the leaves; June. Bracts ovate or obovate, hairy. Anthers 
red. Filaments whitish, hairy towards the base. Ovaries broad, 
sessile, pubescent. Style short. Stigmas rather large. Capsules 
broadly oval or ovate, more or less hairy, about 3 — 4 mm. long. 
Calcareous rocks on mountains, locally abundant. Merioneth- 
shire (see Journ. Bot. 1 , 174 (1912)); Stirlingshire, Perthshire, 
Forfarshire, Aberdeenshire, and Sutherlandshire ; from about 600 
to over 1000 m. 
We have seen the Merionethshire specimen above alluded to. It is in herb. 
Holmesdale, in the Natural History Club, Reigate, Surrey. The plant was 
gathered on Cader Idris at an altitude of about 890 m. 
The pre-Linnaean name for S. reticulata was S. pumila folio rotundo ; but 
Ray (Syn. ed. 3, 449) included in this name N. herbacea. Thus several of the 
early British post-Linnaean records of S. reticulata are clerical errors for 
,S. herbacea. The author (probably James Bolton) of a list of plants in Watson’s 
History of Halifax (177 5) carried this error a step further by recording S. reticulata 
for localities in the West Riding of Yorkshire where neither S. reticulata nor 
S. herbacea is known to grow. 
Northern and Arctic Europe (to 66° N.), Asia (to 70° io' N.), 
and America; mountains of Central Europe (ascending to 2800m. 
in the Tyrol), southwards to the Pyrenees, the Alps and the Car- 
pathians ; mountains of Central Asia ; Labrador. Map 3 - Saltx retlculata occurs in the

S. arbuscula x reticulata (p. 40); S. herbacea x reticulata (p. 28) ; recorded for those marked “?”
