428 ROSA 



glandular ; sepals entire, short, triangular, downy inside and on the margins. 

 Fruit rather pear-shaped or globose, red, i in. diameter, smooth, with the sepals 

 fallen away. 



Native of Western N. America from British Columbia to California and 

 Montana. It has been associated with R. pisocarpa, from which, however, 

 it is readily distinguished by the presence of glands on the younger parts of 

 the plant, the double-toothing of the leaves, and the deciduous sepals. A 

 pretty, graceful plant, introduced to cultivation about 1893. 



R. HEMISPH^ERICA, Hermann. 



(R. sulphurea, Aiton ;, Bot. Reg., t. 46.) 



Growing on a wall, as this rose usually is in the British Isles, it will attain 

 a height of 10 ft. or more ; branches slender, furnished with scattered, slender 

 prickles. Leaflets five to nine, obovate, -^ to i| ins. long, rounded and 

 coarsely toothed at the apex ; smooth and of a glaucous hue above, more 

 glaucous beneath. Flowers solitary, drooping, delicate sulphur-yellow, 2 ins. 

 across, with numerous petals ; flower-stalks and calyx-tube smooth or with 

 glands ; sepals i in. long, the tips coarsely toothed, leaflike. 



This beautiful yellow rose is known to have been in cultivation early in 

 the seventeenth century, but owing to its difficult cultivation has always been 

 very rare. Near London especially it refuses to thrive, and in many places 

 where it grows fairly well, its flowers do not expand properly. It is found in 

 the gardens of Asia Minor, Persia, Armenia, etc. The English climate is too 

 dull and damp to suit it, but one occasionally sees it doing well. In the 

 garden of Bitton Vicarage, near Bath, Canon Ellacombe has had it in 

 splendid health for many years ; and I remember, many years ago, seeing it on 

 the front wall of a cottage between Woking and Knap Hill. The flowers do 

 not open well in cold, wet summers. 



R. RAPINII, Boissier, is generally considered to be the wild type from which 

 R. hemisphserica was derived centuries ago, probably in the gardens of the 

 East. It has fine flowers 2^ ins. across, the five petals yellow. Fruit globose, 

 ^ in. diameter, crowned with spreading, downy sepals. 



R. HIBERNICA, Templeton. IRISH ROSE. 



A shrub 6 to 9 ft. high in gardens, with erect stems and arching branches 

 armed with scattered prickles, the sucker shoots usually very freely furnished 

 with prickles and bristles. Leaflets five to nine, oval or ovate, simply toothed, 

 | to i in. long, downy beneath, especially on the midrib. Flowers pink, 

 usually one to three in a cluster (sometimes more), each on a smooth stalk 

 and \\ ins. across ; sepals with an expanded leaflike tip, more or less pinnately 

 lobed. Fruit globose, in. diameter, red, crowned with the persisting sepals. 



This interesting rose is thought to be a hybrid between R. canina and 

 R. spinosissima. It is, at any rate, fairly intermediate between them. First 

 discovered near Belfast, in 1802, by Mr John Templeton (who thereby won a 

 prize of five guineas for the discovery of a new Irish plant), -this rose has 

 been found nowhere else up to the present, although in England two slightly 

 different forms of it have been discovered. 



Var. GLABRA, Baker. Leaves and leaf-stalks without down. 



R. HISPIDA, Sims. 

 (Bot. Mag., t. 1570 ; R. lutescens, Pursh ; R. spinosissima var. hispida.) 



A shrub up to 6 ft. high, with sturdy, quite erect stems covered with 

 slender, bristle-like prickles. Leaflets five to eleven, oval or obovate, f to
