186 THE JOUJINAL 0¥ JJOTANV 



inflorescence not projecting beyond the terminal leaves of the 

 branches bearing it, solitary, geminate, or in clusters of 3 to 7. 

 Corolla sweet-scented, but calyx and pedicels emitting a strong odour 

 of turpentine, which is absent or only verj- feebly noticeable on the 

 leaves. I wish here to observe that the odour of the leaves and other 

 herbaceous parts in Roses is not always in relation with the glands, as 

 usually stated in books ; I have come across bushes of B. micraniha 

 the leaves of which, though very glandular, were devoid of odour, 

 even when rubbed; whilst, on the other hand, the leaves of a R. dume- 

 iorum (a single bush at Hadley Wood, Middlesex) had the sweet 

 scent of russet-apple characteristic of the Sweet-brier, and Lloyd 

 {Flore de V Quest de la France) attributes to the eglandular or feebly 

 glandular B. Carionii Desegl., an " odeur ruhiginense, quoique 

 faible." 



Prickles straight or feebly curved, rarely falciform, varying much 

 in size and shape, strongly and gradually dilated towards the base, 

 1| to 4 times as long as broad at the base, wdiich is strongly com- 

 pressed ; small near the inflorescence, large on the thicker stems, 

 where they may be very crowded and accompanied by smaller, more 

 slender prickles, the state of things suggesting the '* heteracanth " 

 type ; few but very large on the old woody stems about 20 mm. in 

 diameter* these prickles pale brown or orange, on young shoots 

 sometimes red, or red at the base and greenish yellow at the end. 



Leaves moderate or large (75 to 105 mm. long) on the flowering 

 branches, sometimes very large (up to 170 mm. long) on the barren 

 shoots. Folioles 5 or 7, rather widely set, sessile, ovate or lanceolate, 

 more or less rounded at the base, acutely pointed at the end. If to 

 2\ times as long as broad (26 to 40 mm. by 12 to 23, but up to 52 

 by 34), yellowish green to bright green above, paler but not greyish 

 or glaucous beneath, with distant very short hairs above, closely hairy 

 beneath ; more or less numerous sessile or subsessile small red glands 

 on the lower surface, owing to which it may appear shot with red 

 when viewed obliquely — these glands sometimes much reduced and 

 colourless, or even absent, on the large leaves of the barren shoots ; 

 teeth acutely pointed and compressed, each with 2 to 7 stipitated 

 glands ; 18 to 27 principal teeth on each side. Petioles tomentose, 

 with stipitate red glands and small, curved, j^ellowish prickles. 

 Stipules moderately broad, auricules pointing straight forwards, beset 

 with red glands above and on the sides. 



Flowers up to 50 mm. in diameter, petals fully spread out, bright 

 pink when half -open and in the bud, turning to pinkish white ; disc 

 convex, 4 to 5 times the diameter of the central opening; stigmas 

 forming a rounded head ; stvles smooih or with a few hairs ; sepals 

 shorter than the petals, strongly glandular on the back, woolly on the 

 sides, w^ith 2 or 3 denticulate and glandular pinna?, spread out, not 

 reverted, immediately after the fall of the petals. Pedicels very long, 

 2^ to 4 times the length of the calj^x-tube, which is oblong (7 to 

 10 mm. by 5 to 7), the former with numerous red glands on long 

 ^^hite soft prickles, the latter with similar glands more or less 

 abundant. Bracts mucli shorter than the pedicels.
