DR. F. BUCHANAN WHITE S 



In some specimens the midrib and primary veins, as well as the 

 petiole and margin, are somewhat reddish in colour. 



A willow which Mr. Brebner found on a neighbouring rock to 

 the above much resembles it, but has flatter, more oblong leaves, 

 more closely but shallowly crenate-serrate or almost serrate, 

 more distinctly white-dotted above, less rugose above and less 

 reticulate below, veins less pellucid, and margins less reflexed. 

 I have not yet seen catkins *. 



In Smith's herbarium is a willow labelled in ink " Salicc el-lip- 

 Hea % nov. sp., Clova Mountains, Mr. Thos. Drummond, Mr. W. 

 Kobertson, 1825," and in pencil " I have this as a rounder- 

 leaved var. of S. Myrsinites" It has no catkins, but— from 

 memory — is much like 8. semireticulata. I think that it has no 

 connection with S. Myrsinites. 



X Salix sibtllina, n. hybr. (S. reticulata x S. Lapponum.) 



In Edinburgh University Herbarium are four small specimens 

 of a willow found by Greville near Loch Brandy, Clova, in 

 1 824. They are labelled " possibly a pilose state of 8. reticulata." 



Though without flowers, these specimens so evidently belong, 

 I think, to a hybrid between S. reticulata and 8. Lapponum, 

 that I have ventured to give them a name and a place in this list. 



The twigs are intermediate (between the parents) in character, 

 rather stout, shining, chestnut becoming grey; young shoots 

 slender, somewhat pubescent. Leaves small (the largest 

 inch, but many are much smaller), ovate, ovate-oblong, or su 

 rotund, at first woolly on each surface but more especially below, 

 finally nearly glabrous above and slightly shining ; upper surface 

 at first slightly impressed by reticulate veins ; under surface with 

 primary veins raised, the others scarcely or slightly raised, 

 reticulate ; margin incurved, with obscure glands as in reticulata ; 

 apex obtuse, or with a short cartilaginous point as in Lapponum) 

 base subcordate, rounded, or shortly cuneate ; petioles very 

 short.

 ovary, linear oblong, rather thick, yellowish green.
