By the sides of streams of the G-ANGETIC PLAIN. "Westward to Mt. Aboo in MAR- 

 WAR and eastward to BIRMA and along the lower Himalaya from KUMAON eastwards. 

 MYSORE, Munro. 



A stout bush, erect or with arching subscandent branches ; prickles often in sti- 

 pular pairs, compressed. Leaves 34 in. ; leaflets 3-4 pair, 1^ in. and less, elliptic or 

 oblong, acute or acuminate, finely serrate, shining above, glabrous on both surfaces or 

 tomentose on the under ; stipules small laciniate. Flowers 2-3 in. diam , white, fra- 

 grant, solitary or in short corymbs, rarely axillary and longer pedicelled ; peduncles 

 and pedicels sometimes with glandular hairs ; bracts more or less glandular- serrate, 

 especially below. Calyx-tube obovoid ; lobes caudate-acuminate, quite entire, decidu- 

 ous. Petals retuse. Fruit globose, densely tomentose ; mass of stigmas discoid, ex- 

 serted ; achenes very many, in. long. pale. Except that one is described as scandent 

 I cannou distinguish R. involucrata- from R. Lyetlii. It is the common rose of the 

 Bengal plains and foot of the Himalaya and the only really tropicnl species of India. 

 Lindley's varieties burmana, parvifolia, glabra, and acutifolia (in Wall. Herb.} explain 

 themselves. Wallich's specimen of involucrata var. glabra is stated to come from 

 the mountains of Pundua on the confines of Sylhet, i. e. the Khasia Mts., which I 

 greatly doubt, for I found it in the Jheels only of Sylhet; and Blinkworth's habitat 

 of the Alps of Sirinuggur probably applies to the Dheyra dhoon. Wallich who pro- 

 cured E. Lyellii in Nipal describes it as a large climber in woods, possibly confounding 

 it with R. moschata. Crepin hazards the conjecture that Lyellii is a hybrid between 

 involucrata and moschata, and regards it as a very doubtful plant, under which cir- 

 cumstances I have retained Roxburgh's name of involucrata, which first appeared in 

 his "Cat. Hort. Bot. Calc." in 1 814. 



2. R. anserinaefolia, Boiss. Fl. Orient, ii. 677; tall, subscandent, 

 prickles hooked, bristles C, leaflets broadly elliptic obtuse simply serrate and pe- 

 tioles pubescent beneath or on both surfaces, flowers in few- or many-flowered 

 corymbs shortly pedicelled white, fruit very small globose. 



WUZURISTAN ; alt. 5,000 ft., Dr. Stewart. DISTRIB. Afghanistan and Belu- 

 chistan. 



This is a common wild and cultivated Affghan rose, ascending to 10,000 ft., of 

 which Griffith gathered many specimens, and which no doubt extends within the 

 British frontier, though the nearest hitherto detected habitat is that given above, 

 whence the specimens have very small folinge and flowers. A shrub often 10 ft. ; 

 branches with tew or many unequal stout compressed prickles often in pairs ; branch- 

 lets leaves beneath petioles and calyx covered usually with a rather furfuraceous 

 pubescence mixed on the petioles and calyx with minute prickles and glands. Leaves 

 1-3 in. ; leaflets i-f in., rarely glabrous above, sessile, nerves beneath indistinct; pe- 

 tiole slender; stipules broad, with glandular ovate free portion. Flowers from soli- 

 tirjkto many in a short crowded corymb, f-1^ in. diam., fragrant; pedicels short, 

 glabrous or pubescent ; bracts ovate-lanceolate, densely glandular. Calyx tube glo- 

 bose, usually smooth and glabrous ; lobes ovate-lanceolate, caudate-acuminate, to- 

 mmtose, deciduous ; tips pubescent, sometimes dilated. Fruit smooth, \ in. diam. ; 

 htad of stigmas very large ; aohenes ^--^ in. long. The above description is of the 

 oidinary state of the plant. Stewart's specimens have more obovate green leaflets 

 |in. long, faintly puberulous beneath, and solitary flowers barely 1 in. diam.
