SOME ROSES FROM DOESETSHIHE 21 



Rosa mtcrantiia, var. Lussert. 



Rosa Licssf'rl Lagger and Paget, 1873, was described from 

 Bovernier in Valais, Switzerland ; it was placed in the synonymy of 

 B. "permixta IJesegl. by Deseglise, in whose herbarium an authentic 

 specimen from 13overnier, sent by Lagger, is preserved ; the leaves 

 are much less hairy than in others, likewise from Bovernier (Lagger), 

 at Kew, which explains how Crepin (1882), who had also seen 

 authentic specimens, thought it suggestive of certain varieties of 

 R. tomeiitosa. In my opinion it must be regarded as a variety 

 of B. micrantlia Smith {permixta Desegl.), approaching the var. 

 Brir/cjsii Baker, of which I have examined the types at Kew ; but its 

 glandular pedicels preclude identification with the latter. Christ's 

 var. salvifolia, from the Western Alps of Switzerland, is probably a 

 mere moditication of this variety, and Coste's var. maarophylla, from 

 the Charente-Inferieure and the Ain, may be the same ; liouy and 

 Foucaud's key leads to it. 



The following description is taken from a bush observed on the 

 road from Studland to Corfe Castle : — 



A robust, tall bush, about 6 ft. high, with fiexuous branches. 

 Flowers 2-3 ; corolla bright pink, as in B. ruhiginosa, 40 mm. in 

 diameter ; disc convex, styles smooth ; sepals nearly as long as the 

 petals, with 2 or 3 long, simple or barbed pinnce bearing stipitate 

 glands on the back and on the margin ; calyx-tube elongate, contracted 

 at the neck, 1^ to If times as long as broad, with stipitate glands at 

 least at the base ; pedicel longer than the calyx-tube, densely stipitate- 

 glandular. Leaves large, up to 85 mm. long, bright green, paler and 

 duller beneath ; young leaves tinged with red ; folioles 5, I-3 to 1| 

 times as long as broad, the largest 42 mm. long, perfectly rounded 

 or more or less acuminate at the end, more or less narrowed at the 

 base, sometimes truly obovate, petiolulate, with scattered hairs on 

 both sides, densely tomentose on the ribs, with small sessile glands 

 on the lower surface ; serrature deep, open, compound, with numerous 

 glands, feeble or obsolete at the base ; the larger folioles with 12 to 

 18 principal teeth on each side ; petioles tomentose-glandular, with 

 numerous acicles and rather strong, curved prickles. Prickles on 

 flowering branches uniform, strong and hooked. 



One of the best characters for distinguishing B. micrantJia from 

 B. ruhiginosa appears to me to be the more convex disc in the former, 

 beyond which the smooth styles project considerabl}'- after the fall of 

 the stamens, sometimes answering to the definition of B. stylosa. 



THE HOME OF INULA HELEN lUM. 



Bt C. C. Lacaita, M.A., F.L.S. 



Elecampane has been cultivated for the properties of its root 

 from time immemorial in sundry parts of Europe. This has led to 

 its establishment here and there as a naturalised alien in many regions 

 where it has no claim to be indigenous ; such, for instance, are Great
