both soon nearly glabrous ; margin slightly cartilaginously thick- 

 ened, entire or with a few minute glandular teeth, especially 

 towards the base ; petiole medium in length, channelled above, 

 more or less tinged with purple, which colour sometimes also 

 spreads to the midrib, veins, and margin, though these are more 

 frequently yellowish ; stipules, when present, rather small, ovate, 

 glandular-toothed. Catkins ( d) terminal on the branches, 

 sessile, short but stout (| x | inch) ; scales roundish, spathulate, 

 rather broad, thin, brown with darker veins, densely pubescent 

 on both surfaces with long straight white hairs; filaments 

 glabrous ; nectary half surrounding the base of the filaments, 

 short, split into 2 or 3 obcuneate pieces. 



From Salix Ian at a the more erect growth, shape of the leaves, 

 and sessile woolly catkins seem to have been derived ; whilst to 

 S. reticulata the smaller size and glabrosity of the leaves, the 

 brighter green of the upper surface, the colour of the petioles, 

 veins, and margins, the rounded scales of the catkins, and above

reticulation of the underside of the leaves is not greater than that 

 which may often be seen in S. lanata, but the faint glandular 

 toothing is very similar to what is shown by some specimens of 



S. reticulata.

I have seen other plants which may also prove to be hybrids of 

 S. lanata and 8. reticulata, but judgment on them must be 



reserved till a larger series of specimens has been obtained.

Mr 



Haggart found, two or three years ago, a very small willow whose 

 affinities at first sight were rather difficult to determine, but which 

 after much consideration I concluded to be with 8. lanata and 

 8. herbacea, in whose company it grows. More recently I have 

 found in the same locality another form of the plant, and its cha- 

 racteristics seem to point pretty clearly to a parentage from these 



species. 



It may be expedient to describe both forms. Though I have
