SOME ADDITIONS TO THE DORSET KLOIIA. 75 



now accepted as a species, and is a type Avitli sonic varieties. The 

 Dorset form differs from any variety tliat I am acquainted with in 

 some slight particulars, though very like at first sight the more 

 typical form of B. sepium, Thuill., which I found two years ago on 

 the Hampshire Downs. How the rose came to bo established on 

 the Melbury Downs is open to question. All the evidence is 

 against its being an introduction by the hand of man ; the locality 

 is at a distance from hedge or cottage, where there could be no 

 object in planting it ; nor is this a rose suitable for hedges. If 

 introduced it Avill have been by the agency of birds, the heat of 

 their bodies doing no injury to the hard seeds of hips and haws, 

 holly berries, yew berries, and the like, prol)ably rather assisting 

 more or less the i^rocess of germination. There is, however, no 

 reason why the rose should not be a survival rather than an 

 introduction ; it is certainly native on a similar formation in South 

 Hants, and presumably so in the adjoining county of Wilts. 



Galeopsis infennedia, Yillars, G. Ladauuin, Linn. Herb. (Fries 

 Herb. norm.). Some explanation is necessary as to nomencla- 

 ture. The narrow-leaved Hemp-nettle of chalky cultivated fields, 

 ■which is Avell distributed in P]ngland and common in some 

 parts, has usually been called G. Ladamim, Linn. It stands 

 so in the Flora of Dorset (Lst Ed.) ; and also in the 7th Ed. 

 of the London Catalogue, where (/. intermedia, Vill., is placed 

 as a variety under it. In the 8th Ed. Lond. Cat. tlie common 

 form api)ears as a species under the name G. antju^tifolia, 

 Elirli. G. intermedia disajDpears, and is replaced by the old 

 name G. Ladcmum, whicli, however, now stands for the rare 

 plant and not the common one. Apparently the existing speci- 

 men in the Herbarium of Linnaeus is not our common plant, 

 but identical with the rarer form G. intermedia, Villars. The 

 common form, the narrow-leaved Ilemp-neLtle, haslieeii long kiii>wii 

 for the county. It is the rarer plant that 1 now i>ut U[ii)n reeonl, 

 the G. Ladayium, L., of the 8th Ed. Lond. Cat., the G. Ladanuni 

 var. intermedia of the 7th Edition. It dillers cliielly by liaving a 

 more glandular inllorescence, broader leaves, rounded instead of
