 "A straggling briar, G — 7 feet high. The branches bright green, red- 

 dish brown on the sunny side ; armed with strong, scattered, hook- 

 ed, neaj-ly equal prickle.s (rarely straight and then much closer 

 together) and no setse. Leaves distant, pale or dark green, fre- 

 quently tinged with red in exposed situations, usually much blister- 

 ed by the sun, quite free from pubescence ; stipules rather dilated, 

 a little reflex ed, acute-pointed ; petiole armed with a few, little, hook- 

 ed prickles ; leajlets 5 — 7, ovate or oblong, acute or rounded, sessile 

 or subsessile, flat or concave, even or rugose, coarsely or finely, 

 simply or doubly serrated, the serrature^ ahvays acute, without 

 glands, and converging. Cymes 1 - or many-flowered ; hractea" ovato- 

 lanceolate, appressed, acute, concave or flattish, finely toothed and 

 glandular at the edge ; peduncles iiX\A. calyx smooth; tube ovate; 

 segments of the cahjx spreading, sharp-pointed, somewhat divided ; 

 petals obcordate, concave ; disk very thick, elevated ; stijles nearly 

 smooth, distinct, included or a little exserted. Fruit ovate or ob- 

 long, scarlet, shining without any bloom ; pc)v'c«?-ps large uneven. 

 " Surely it is not surprising that the most common species of the ge- 

 nus, whose fruit is scarcely ripe before it is devoured by small birds, 

 and depo.sited by them in every variety of soil and situation, should 

 frequently assume features considerably dissimilar to its original ap- 

 pearance ; and yet, upon such difterences, which in less variable genera 

 would hardly have been trusted, have v.riters upon Roses attempted to 

 establish their species. Much stress has been laid on the circum- 

 stance of pubescence ; en its absence, presence and quantity R. col- 

 Una, dnmetorum and canina of authors, and hractescens of Woods, 

 arc divided from each other : yet a careful observer may trace 

 them running into each other. The var. cassia is a curious plant, 

 first taken up in E. B. It is scarcely found out of the Highlands 

 of Scotland, and even there very sparingly. Its very glaucous hue 

 distinguishes it. There is a remarkable peculiarity in R. can., that the 

 further to the North any var. of it is found, the more villous are the 

 styles ; and the less so as it proceeds southwards 5 these organs being 

 quite destitute of hair in Madeira. — In Tartary, Russia and Siberia, 

 an esteemed drink is made from the twigs andleaves ; and the flowers 

 yield a spirit, and are preserved with honey and sugar by the inhabi- 

 tants of the Volga and Ukraine." L.
