436 BOTANICAL GAZETTE [JUNE 
notched; gland about o.5 mm. long; scales oblanceolate, obtusish 
or acute, pale brown, nearly glabrous outside, thinly pilose inside, 
about o.8 mm. long: staminate aments slender, spreading, 2-3 cm. 
long, 1 cm. wide; stamens 2, filaments glabrous, free; anthers short, 
obovate to nearly round, reddish or purplish; scales as in pistillate 
ament. 
Salix Farrae Walpoleii is separated readily from the species by the 
pubescent-pilose young twigs, the broader, more obovate leaves, the longer 
and laxer aments, and the shorter styles. Walpole’s no. 1624 in the United 
States National Herbarium is designated as the pistillate type. His no. 1742 
has the best aments of any of the three staminate specimens seen and is 
designated as the staminate type. The variety flowers from about June 20 
onward through July or early August, according to location. This willow 
rather closely resembles S. balsamifera (Hooker) Barratt, from which, however, 
it is readily separated by the entire leaves, seldom rounded and never cordate 
at base, the short pedicels, and somewhat shorter styles. Its nearest relative 
on the S. cordata side is S. mackenziana (Hook.) Barr., from which it is sepa- 
rated easily by the thin, entire, elliptic-obovate leaves, and more especially 
by the short pedicels. The variety is named for F. A. WALPOLE, since deceased, 
who collected several specimens of it in the vicinity of Port Clarence, near 
Cape Prince of Wales, Bering Strait, the most western locality at which it has 
been found. The specimens referred to it are cited later. So far as known, it 
is the only member of the section CorDATAE with an exclusively Arctic distri- 
bution.
