SOME SCOTTISH WILLOWS. 859 



cultivated specimen is the apparent denudation of the leaf, the 

 disappearance of the downy or hairy clothing of the young leaves 

 and twigs in cultivation. But this is more apparent than real, 

 though perhaps real to some extent. In cultivation the leaf-surface 

 is much increased, it may be by three or four times ; and if the 

 number of hairs on a leaf remains stationary, the larger leaf of 

 cultivation will appear to be three or four times less hairy than 

 the wild leaf. The same explanation applies to the twig, which 



elongates in cultivation. 



Wild specimens of a few of the following willows have been 

 formerly sent to Dr. White by one of us, and his opinion is usually 

 given in each instance in which it assisted us to a determination. 

 In particular we owed to him the naming of our 8. aurita x 



Myrsinites. 



The hybrids are mentioned in an order partly natural, partly 

 alphabetical. The two originating species are named in alpha- 

 betical order, to designate each hybrid; and the hybrids are arranged 

 in the order of the first named of the two species, as they stand in 

 the London Catalogue. 



Salix cinerea x phylidfolia.—(l) About a mile below the Inn at 

 Clova ; a good intermediate form ; fruit not seen on original bush, 

 the leaves of which were uniformly small, 1-1$ in. long, and much 

 spotted and blotched by the punctures of small larva. Leaves 

 covered with silky hair when young, but soon glabrescing ; glaucous 

 beneath ; margin regularly serrate. Under cultivation the main 

 features are as follows :— Young shoots more or less pubescent at 

 first, but glabrescent, reddish brown when fresh, but drying dark 

 brown ; leaves 2-3 in. long, on petioles £-£ in., puberulous above, 

 oblong-ovate, acute, pubescent only while young ; margm crenate, 



serrate, nearly flat. Catkins about H «»« lou g' Wlth 3 or 4 lea {y 

 bracts; ovary narrow conic-ovoid, very silky; style moderately 

 long ; stigmas moderate ; scale narrow, obovate, blunt or rounded 

 at their top ; nectary about half the length of the short pedicel. 

 (2) Another plant from the same part of the valley has truit (in 

 cultivation) of 8. phylicifolia , and no evidence m the catkin of any 

 other origin, except the scale, which is that of cinerea; but in the 

 leaves the cinerea element is the most obvious, and when found, 

 without fruit, the bush was taken for a cinerea variety. We consider 

 this hybrid not uncommon in this part of the valley ; a fine bush 

 also grows at the east end of the foot-bridge near the Kirk at Clova, 

 which comes very close to the first-mentioned form. A male bush 

 is in cultivation at Shirley, which was brought from some part of 



this same valley. «,,.-.% ft , ,,- i 



S. cinerea x nigricans {S. strepida Schleich.).— Of this we have 



specimens (but no root) from a large bush low down m Glen 

 Lochay, near Killin, in which the cinerea influence comes out 

 strongly in the wood, leaves, and stipules ; while 8. nigricans is no 

 less obvious in the colouring of the leaves, both in the fresh and 

 dried state. We have also a plant in cultivation of this hybrid, 

 iust intermediate, from Glen Lyon, a few miles above Fortingal, 

 Mid-Perth. With these we may mention a plant (male) which is
