172 ANNALS OF SCOTTISH NATURAL HISTORY 



V. Teeth double or composite, pedicels hispid-glandular, 

 sepals glandular on the back. 



5, from Mid Perth and East Perth. 



" In No. 40 there are glands on the receptacles. No. 

 407 of the parcel of 1895 has irregular toothing and glands 

 on the receptacles." 



VI. Teeth composite. Leaflets with glands on 

 veins of the under surface. 



I, from West Perth. 



" In this form the petioles are somewhat pubescent all 

 round, but they become glabrous with age. The midrib is 

 likewise somewhat pubescent, but it also becomes glabrous 

 with age. This thin pubescence shows the tendency of this 

 form to approach R. coriifolia" 



Forms of R. glauca with glands on the veins below seem 

 to be very rare, at least in Perthshire. I have reason, how- 

 ever, to think that they may be rather more numerous than 

 as yet they appear to be. If I have observed rightly, the 

 glands, which are fairly numerous in the flowering stage of 

 the bush, gradually wear off until it is only on a leaflet here 

 and there that they can be detected. I have several speci- 

 mens from different localities in this latter state, and shall 

 try to gather them next season in the flowering state as well 

 as in fruit, so as to make certain that what I have stated 

 above is actually the case. 



R. CORIIFOLIA (Fries.'} 



I. Teeth simple, pedicels and sepals without glands. 

 1 1, from East Perth, Mid Perth, and West Perth. 



" It is to this sub-division that the type of R. coriifolia 

 (Fries.) belongs. The No. 414 is a variation peculiar in the 

 elliptic form of its leaflets. Notice also that certain leaves 

 of the flowering branches have nine leaflets."
