81 THE BRITISH WILLOWS 



late, pubescent in the upper half then subglabrescent ; pedicels 

 thinly pubescent elongate, at length 2-3 times as long as the linear 

 nectaries ; stigmas cleft, rather shorter than the long styles. 



This singular hybrid was discovered on Muckish Mt., Donegal, 

 by Dr. David Moore, and described by him, as a " form of 

 S.arbnscula," in Journ. Bot. 1870, 209; and, thanks to Sir F. W. 

 Moore, who sent it me from Glasnevin Gardens, has been under 

 observation in the garden for many years. That S. herbacea is 

 one of its parents is obvious. As to the other, there has been 

 some difference of opinion. B.White (I. c.) suggested S. nigricans, 

 which would account for the pubescence of the foliage but not for 

 its bright colouring and the absence of any blackening when dried, 

 nor for the pubescence on the ovaries. S. J. Enander wrote his 

 opinion on the sheet (No. 109) in the British Museum that it was 

 S. herbacea x lapponum ; and on learning that S. lapponum was 

 not an Irish species, suggested in a letter that it was a form of 

 S. cemua (S. herbacea x repens). The pubescence of the young 

 twigs and leaves would thus be accounted for, and the habit of 

 the plant. On the other hand, from this combination narrower 

 leaves and short obtuse buds and rather short styles would be 

 expected ; whereas the leaf- blades are broadly oval, the buds 

 pointed and often subacute, and the styles remarkably long. 

 S. Moorei is therefore left under S. herbacea x phylicifolia, as its 

 probably right place. 



Native only in Donegal, Ireland ; and in Jemtland, Sweden.

A very dwarf prostrate or ascending shrub with slender 

 branches pubescent at first ; buds ovoid, pointed or obtuse, soon 

 glabrescent. Stipules 0. Leaf-blades i-f (-1 cult.) in. long, 

 usually ovate or oval sometimes obovate, serrate with small rather 

 distant teeth or subentire, rounded or narrowed at the base, 

 thinly or silkily pubescent at first, glabrescent and reticulate on 

 the upper surface, dull green or glaucous green beneath. Catkins 

 coeval on leafy peduncles, fl. May, June; 8 \-^ in. long, with 

 oblong or slightly obovate bracts obtuse or rounded above, crimson- 

 rimmed, thinly ciliate, otherwise glabrous, concave ; filaments 

 glabrous ; nectaries two (one in front of and one behind the 

 filaments) linear-oblong ; anthers fading a light brown ; ? £-f in. 

 long on 3-1-leaved pubescent peduncles, somewhat elongate in 

 fruit ; bracts obovate-oblong, rounded above, ciliate and with 

 some hairs above otherwise glabrous, involvent, light green or 

 turning reddish upwards ; ovaries ovoid-conic, somewhat pubes- 

 cent or glabrous ; nectaries linear to oval-oblong, pedicels glabrous, 

 as long as the nectaries at first, at length 2-3 times as long ; 

 style stout as long as the rather large divided stigmas.
