A LIST OP BRITISH ROSES 47 



R. COMOSELLA Desegl. & Ozan. in Bull. See. Dauph. p. 327. 

 This may be regarded as a form of B. comosa with smaller oval 

 leaflets, and more numerous, slender, straighter prickles. Its 

 fruit is ovoid. It runs very near var. rotund if olia. It is a com- 

 mon form on Box Hill. V.-c. 17. 



R. EUBiGiNOSA var. ROTUNDiFOLiA Eau, Enum. Eos. p. 136. 

 Knov^n by its small suborbicular leaflets, rarely more than | in. 

 long, straightish or somewhat falcate slender prickles, and sub- 

 globose fruit. V.-c. 3, Somerset, 16, 17, 62, Northumberland?. 



R. ECHiNOCARPA Eip. OX Desegl. Ess. Monogr. p. 110. This 

 has a mixed armature of very numerous prickles, the larger ones 

 being hooked though not stout. The fruit also is aciculate, 

 usually strongly so. I have seen no further specimens than those 

 mentioned in B. E'. pp. 106, 107. Groves's No. 38 is no doubt 

 B. comosa. V.-c. 17, Perth. 



R, Gremlii Chr. ex Grem. Exc. Fl. Schw. ed. 2, p. 176. I think 

 Barclay's Caputh specimen (Wats. Exch. Club Eept. 1907-8, 

 p. 143) must be referred here, though it is not typical, and may 

 be only a white -flowered form of B. echinocarjja. Uniform, long, 

 slender, hooked or falcate prickles, yellowish-green foliage, longish 

 styles, and white flowers are the leading characteristics of the 

 species. Sudre named the example that was sent to me " near 

 B. echinocarpa, but with small leaflets." Dingier says he sees 

 no resemblance to that species, though he does not give it a name. 

 V.-c. 89. 



R. JENENSis M. Schulze in Mittel. Geogr. Gesell. Thur. Jen. 

 iii. p. 79. No specimen other than that mentioned in B. R. 

 pp. 108-9 has come to my notice. V.-c. 15. 



GROUP MICRANTHA. 



Usually known from the Eglanteria group by their glabrous 

 styles, its members have as a rule a much laxer habit, like that of 

 most of the Eu-canincB. ; their sepals are reflexed and deciduous, 

 and the fruit always narrowed at the apex, rather than at the 

 base. In most species the prickles are uniform, but occasionally 

 a mixed armature is seen, generally just below the inflorescence, 

 as is frequent in the Eglanteria group, though sometimes also on 

 the main stem. 



R. MICRANTHA Sm. E. B. tab. 2490. The bulk of our plants 

 belong to this species or the next. It is generally easily recog- 

 nized, but it varies considerably in shape and size of leaflets and 

 fruit, and our forms are probably capable of segregation. I have 

 it from Cheshire with numerous acicles just below the inflorescence, 

 but with smooth fruit, which, however, is much too ellipsoid for 

 var. trichocarpa. Dingier named this form var. microcarpa Kell., 

 which it certainly resembles, but Sudre thought it just B. 2)er- 

 mixta. A form with larger, rounder, more hairy leaflets occurs 

 near Hindhead, Surrey, which may be B. septicola Desegl., but it
