are labelled by Greville, " Collington "Woods, 1824," have 

 female catkins, and belong beyond doubt to S. Lajyponum. 

 There, however, seems to be no such place as " Collington " 

 near Edinburgh, but it is certain "Colinton" is meant, since 

 I have seen the name both printed and written " Collington." 

 It would be of much interest to know if the species still 

 occurs there, and if it is indigenous. I have seen it grow- 

 ing on the Ochils at so low an elevation as 700 feet, perfectly 

 W'ild, and unassociated with other alpine plants. 



Sheet 319. — Labelled by Winch, " Salix glauca, Ben 

 Lawers," and in another hand, " Salix arenaria v. glauca, 

 Smith." Smith's glauca has long been known to be different 

 from true glauca, L., and has been supposed to be either not 

 British or to be only a slight variety of S. Lapponum. There 

 is no doubt, however, that it is the same as >S^. helvetica, Vill., 

 now considered to be a variety or sub-species of S. Lapponum. 

 If Winch's specimen really came from Ben Lawers (and 

 there seems no good reason to doubt it), it should be looked 

 for again. It- is the only reputed icild British specimen of 

 Smith's glauca which has come under my notice. 



Sheet 330. — Amongst 8. Arhuscula, and labelled by (I 

 think) Professor J. H. Balfour, "Glen Dole, 1826," is a 

 specimen which, though fiowerless, must be referred to aS'. 

 spuria, Willd. {LapponiLm x Arhuscula). I have seen other 

 and more recent examples with catkins from Clova, and the 

 hybrid also occurs on the Breadalbane Mountains. 



Sheet 336. — " Salix Myrsinites, Eng. Bot., Clova Moun- 

 tains, 1824," Dr Greville. " Either jMgrsinites or possibly S. 

 Grahami," Leefe. I think that these specimens, which are 

 fiowerless, have no connection with S. Myrsinites, but are 

 probably my S. sohrina {Lap2wnum X herhacea). I have found 

 fiowerless specimens in Perthshire, and have received catkins 

 from Clova, collected by Eev. E. S. Marsliall. Dr Greville's 

 examples are nearer herhacea tlian the others 1 have seen. 



Sheets 337, &c. — A number of specimens from Clova, 

 Caenlochan, Glen Callater, Ben Avon, &c., collected by J. H. 

 lialfour. Brand, and perhaps Greville, and named Myrsinites 

 and nigricans, belong to >S'. Wahlenhergii, And. {Myrsinites X 

 nigricans). Tliis hybrid has often been passed over for one 

 or otlier of its parents. It is not quite certain that it should 

 not bear the name /S'. Macnalnana, Macgilliv. I liave not been
