group of species, with little affinity to each other, except in 

 the circumstance of being almost universally deprived of 

 prickles. It would therefore be better perhaps to refer the 

 present plant to the neighbourhood of Rosa rubella, with 

 which it has many points of resemblance, and from which it 

 does not very materially differ. It would seem from Pallas's 

 account of his Rosa alpina that he has actually confounded 

 two different things under that name; — one not perhaps 

 differing from R. alpina of Europe, and the other &arly re- 

 lated to R. rubella; at least, if the last be the same as what 

 Marschall von Bieberstein has called Rosa pygnwea, and 



which does not appear, as far as we can judge from the de- 

 scription, essentially different from that plant. 



Shrub 2-8 feet high: branches spreading or upright, 

 dark-green, generally with a glaucous hue, without thorns 

 or prickles, or very rarely having prickles towards the root 

 or on the branches, then being stipulary. Leaves thickset, 

 spreading, opaque : stipules flat, narrow, a little widened at 

 the end, unfurred (destitute of all hairy or villous substance), 

 glandularly ciliate: petioles unfurred, with thickset glands 

 and intermingling unequal bristles: leaflets 5-13, ovate, 

 acuminate at both ends, simply or doubly serrate, quite 

 bare, grey-blue underneath, midrib often roughened over 

 with small prickles. Flowers upright, either very red or 

 rose-coloured, usually solitary; peduncles without prickles, 

 or bristly; tube of the calyx elongatedly ovate, bare or with 

 bristles; leaflets ovate, acuminate, undivided, sometimes 

 foliaceous at the end, on the outside hairily furred, without 

 prickles, or bristly. Petals obcordate, upright, concave: 

 disk obliterated, staminodia (the part supporting the sta- 

 mens) often very conspicuous, flat: stigma-mass convex, 

 protruding. Fruit scarlet, elongated or else obversely 

 ovate, rostrate, cernuous. Lindley MSS,
