Two other species are common in the North- West Himalaya : R. niveus, 

 Wall., at 7000 to 11,000 ft., from Kashmir to Bhutan ; leaves trifoliolate, some- 

 times impari pinnate, with broad ovate leaflets, the terminal leaflet often lobed ; 

 long subulate stipules ; calyx-segments often more than \ in. long, much exceed- 

 ing the small red petals ; and red or yellowish brown fruit : R. macilentus, 

 Camb. in Jacq. t. 60, Kashmir to Sikkim, between 5000 and 8000 ft., with 3 

 ovate-lanceolate leaflets, often 1 only, white petals as long as calyx, and bright 

 yellow fruit. 



4. ROSA, Linn. 



Erect scrambling or climbing shrubs, more or less prickly, with impari- 

 pinnate leaves, serrate leaflets and stipules more or less adnate to the peti- 

 ole. Flowers terminal, solitary corymbose or paniculate. Calyx-tube per- 

 sistent, globose urceolate or ovoid, mouth contracted, limb divided into 5 

 foliaceous segments. Disc coating the calyx-tube. Petals 5, rarely 4. 

 Stamens numerous, inserted on the edge of disc, at the mouth of calyx- 

 tube. Carpels free below, many, rarely few, enclosed in the calyx-tube, 

 the styles protruding from the tube, and occasionally united. "When in 

 fruit, the carpels are dry, hairy, 1-seeded achenes, enclosed in the more 

 or less succulent calyx-tube, the whole forming a dry or pulpy red or 

 black berry.

Numerous species are cultivated in India. Those more generally grown with- 

 out, however, any reference to garden varieties and hybrids may be classed as 

 follows, the groups being partly taken from Lindley's Kosarum Monographia, 

 London, 1820, partly from Boissier's Fl. Orientalis, ii. 669. The characters 

 given are those commonly assigned to each species, but cultivation and crossing 

 have created such a multitude of forms, that in many cases it is impossible to 

 recognise any satisfactory specific distinctions. 



A. Styles Distinct. 



I. Bracteatce. Fruit and branchlets clothed with dense persistent woolly 

 tomentum ; flowers bracteate ; prickles twin, mostly infra-stipular. 



1. R. involucrata, Eoxb. Fl. Ind. ii. 513 ; Wight Ic. t. 234. Flowers sub- 

 sessile, large, white, fragrant, surrounded by large pectinate, woolly bracts. 

 Indigenous in Bengal and the Eastern Himalaya. 



2. R. Lyelliiy Lindl. 1. c. t. 1. Flowers pedunculate, large, white or blush ; 

 bracts linear, hoary, entire. Indigenous in Nepal, Kamaon, and on Mt. Aboo. 



3. R. bracteata, Wendl. ; Redoute les Roses, i. 35. Flowers large, white, 

 solitary, surrounded by 8-10 ovate imbricate, finely pectinate bracts. China 

 Macartney's rose, with double fl., believed to belong to this sp. 



II. Eglanterio3. Prickles scattered, of two kinds, some slender, setaceous, 

 others stout, straight, or curved ; flowers yellow or red ; calyx-lobes persistent 

 in fruit. 



4. R. Zwfea,<Mill. (see below). 



5. R. sulphurea, Aiton. Flowers large, yellow, always double ; leaflets 7,
