THE FLORA 119 



of species the 3000 or so of varieties now in cultivation 

 have been produced. These are, for convenience, grouped 

 into many classes Tea Scented, Hybrid Teas, Hybrid 

 Perpetuals, Climbing, Eamblers, Chinese, Ayrshire, etc. 

 They are of all sizes, from the miniature fairy roses, less 

 than 1 foot in height, to strong climbers which send out 

 shoots 12 feet long, and more, each season. There are 

 singles and doubles in almost every conceivable shade of 

 colour. Otto or attar of roses the finest perfume prepared 

 is obtained, by distillation, from the petals of various 

 sweet-scented kinds. As a political emblem e.g. the Red 

 Rose of the House of Lancaster, the White Rose of the 

 House of York, etc. the Rose is historical. The best of our 

 garden varieties are budded on to the Briar or some other 

 hardy kinds. The following, collected in the north-eastern 

 end of the island (in September mostly), were kindly named 

 by Mr W. Barclay, Perth. 



JR. spinosissima, L. Burnet or Scottish Rose. Dreas-nam- 

 Mucag. Dry slopes and banks. A fine brown dye (with 

 copperas) is obtained from the plant. June. The Scottish 

 Roses have originated from this species. 



R. spinosissima, f. Sheltered situation, Glasaird. 

 Specimens of this, which were at first thought to be the 

 var. Ripartii, Desegl, have been described by Mr Barclay as 

 "a variation which differs from the type in having glandular 

 peduncles, teeth of the leaves irregular, many simple teeth, 

 but with a good many having a toothlet attached, which 

 sometimes bears a gland. I do not think it has been 

 specially named. Var. Ripartii has composite glandular teeth, 

 and besides has the midrib and veins of the underside of 

 the leaves more or less glandular, which is not the case with 

 the specimens submitted." June. 



R. tomentosa, Sm. Rudha-na-Coille-bige ; not uncommon. 

 "The tomentosa forms do not differ very much from each
