REVISION OF THE BRITISH WILLOWS. 441 



knotty, tortuous, reddish-brown glabrous branches. The leaves 

 are small, oval, at first woolly on each side, but becoming sub- 

 glabrous, and slightly shining on each surface ; margin obscurely 

 serrate; base rounded; tip (sometimes twisted) subacute and 

 subcartilaginous, as in Lapponum', veins and margin pellucid; 

 veins finally raised and reticulate on the upper surface ; lower 

 surface lineately veined and reticulate with raised veins. Catkins 

 short, few-flowered, lateral on long leafy peduncles; scales 

 large and broad, obovate, subtruncate, brown with darker tips 

 and long white hairs; capsules sessile, white-woolly, at first 

 conical, then subulate-conical ; style moderate, about as long as 

 the rather thick entire or bifid suberect stigmas ; nectary long 

 linear. Young shoots pubescent. 



A willow from Clova (Dr. Greville, 1824), in Edinburgh 

 University Herbarium, may belong here, but if it does it is 

 nearer herbacea than the above. It has leaves only. 



Since this description was written I have received specimens 

 °f 8. Lapponum-herbacea (no authority for the name, and 

 8. alpestris, And., given as a synonym) from Sweden. These are, 

 to all intents, the same as the Scottish plant, though rather more 

 luxuriant. " Alpestris " is the name adopted by Andersson (in 

 the 'Norges Flora') for the hybrid between S. herbacea and 

 & glauca, and is placed with four other, variously composed, 

 hybrids under 8. norvegica (Fr.), And. 



I have also seen a more numerous series of specimens col- 

 lected in Clova by the Messrs. Linton, as well as what appears to 

 be another form (collected by the same botanists) from Craig- 

 na-dala Beg, Aberdeenshire. These specimens exhibit various 

 degrees of combination between the supposed parents.

X Salix Margarita, n. hybr. {8. herbacea X 8. aurita.) 

 In Messrs. Groves' herbarium is a very curious willow, found 

 by them on Craig Loigste, on the south side of Ben Challum, in 

 Perthshire, in 1855 • and growing in the Edinburgh Botanic 

 Garden are two willows (for specimens of which I am indebted 

 t0 Mr. Lindsay, the Superintendent) which, though not identical 

 Wl th the Messrs. Gr oves' plant, are apparently another form of 

 tbe same species. The Edinburgh Garden plants were found in 

 Jf 7 5, by the late Prof. Dickson and the late Mr. J. Sadler, near 

 T yndrum, and probably both on Ben Challum, since a specimen
