SALIX

Regarded by Borrer and Baker {op. cit.) as connecting S. herbacea and S. polaris ; but the catkins, formed from lateral 
buds and borne on leafy peduncles, do not support this suggestion. The same objection applies to Nyman’s view {Consp. 
671 (1881)), followed in the Index Kewensis , that the plant should be placed under S. retusa. Sir J. D. Hooker ( Student’s 
Flora ed. 3, 376 (1884)) said it appeared to him to be a form of S. myrsinites , with smaller catkins, paler bracts, a glabrous 
capsule, and a long silky gynophore. Syme {op. cit.) thought it might be a hybrid of S. herbacea with either S. nigricans or 
S. phylicifolia. White {op. cit.) referred it doubtfully to S. herbacea x phylicifolia. Linton {Ann. Scott. Nat. Hist. 239 (1894)) 
argued strongly that it should be referred to S. herbacea x myrsinites. Enander 1 , perhaps unaware that all the specimens are 
alleged to have come originally from the same pistillate plant, has referred some examples to S. herbacea x lapponum , others to 
S. herbacea x lapponum (x lanata ?), and still others to herbacea x lanata. 
That the plant does not conform to any known species is clear, and that it is a hybrid is a very reasonable suggestion ; 
but the various hypotheses regarding its supposititious origin, offered by leading Salicologists, afford conclusive proof that the 
task of determining the putative parents of doubtful hybrids by morphological evidence alone is, at least in certain cases, an 
impossible one. Until careful and critical experiments in hybridisation have been performed, no certainty can prevail. 
Said to have been collected by Professor Graham in Sutherlandshire, and to have been brought by him to 
the Royal Botanic Garden, Edinburgh (Baker, loc. cit.).

Very similar to x S. grahami. Laminae of young leaves duller and rather more hairy, 
rather less rounded at the two ends, rather narrower in proportion to the length. Bracts obovate, 
much shorter, ciliate towards the summit. Ovary slightly pubescent towards the apex, stalked, 
stalk glabrous. Capsules on a long stalk. 
The first mention of this appears to be by D. Moore in fourn. Bot. viii, 209 (1870), where the plant was referred to a 
form of S', arbuscula. The plant is there said to have been first collected, on the top of Muckish Mountain, co. Donegal, 
in September, 1866. Authentic examples by Dr Moore are in Herb. Kew. See also fourn. Bot. ix, p. 300. 
White suggests that x S. moorii is a form of S. herbacea x nigricans , Linton {fourn. Bot. xxxiv, 438 (1896)) that it is a 
form of S. herbacea * phylicifolia, and Enander (in Herb. Kew.) that it is S. herbacea x lapponum. S. lapponum is not usually 
regarded as an Irish plant; but there is a doubtful record of it in Watson’s Cybele Brit, iv, 212 (1859); and it has to be ad- 
mitted that Irish willows have never been thoroughly investigated. 
Known only from co. Donegal, Ireland, and cultivated in botanical gardens.

Andersson first described the plant {S. phaeophylla) which later authorities have held to have this parentage ; but Enander 
states {Sched. i, 16 (1911)) that all the original specimens are S. herbacea x lapponum (see page 35). 
Very critical ; recorded for Forfarshire.

A plant, said to have this parentage, was recorded by the Rev. E. S. Marshall {fourn. Bot. xxxi, 228 (1893)) 
from Forfarshire. This appears to be the first record of the hybrid ; but no description was then published. 
Also recorded for Sweden.

Mus. Brit., in Herb. Kew., and in herb. White. Most of Enander’s suggestions are adopted in this work.
