dantly stored with R. Idseus, suberectus and Koehleri, in juxta-posi- 

 tion, but could never meet with even a suspicious specimen ; and no 

 one has ever noticed any step between R. Idaeus and other fruticose 

 brambles, where the hybrid, if in existence, would be so easily distin- 

 guishable. 



" I therefore consider that the numerous forms of the fruticose Rubi 

 are due to situation, aspect, age, and luxuriance of growth ; so that it 

 becomes useful to trace, if possible, the changes that circumstances 

 may cause in one species. With this view I have directed my atten- 

 tion to the vitality existing in the stems of brambles, which I find far 

 greater than usually supposed, or hitherto recorded, and thus the very 

 great difference apparent in specimens of the same species is account- 

 ed for, as well as the difficulty that often presents itself in determin- 

 ing dried specimens." — p. 177.

1. Jung, punctata, Taylor. " Caule casspitoso, erecto, ramoso ; fo- 

 liis subapproximatis, rotundato-ovatis, apice atque hinc margine spi- 

 noso-ciliatis, recurvato-convexis ; calycibus axillaribus, ex angusta 

 basi late obovatis, compressis, hinc longioribus, illinc fissis, ore aperto 

 spinoso-ciliato." — p. 179. 



Woods at Cromaglown and mountains of Kerry, abundant. Long 

 confounded with J. spinulosa {Dicks.), but differing in its smaller size, 

 its patent leaves, which are less decurrent on the upper side, more 

 rounded, and with punctate cells ; and by its more densely and deeply 

 ciliated shorter calyces. 



2. Jung, exigua, Taylor. " Caule caespitoso, adscendente, subsim- 

 plici; foliis rotundato-obovatis, patentibus, remotiusculis, integerri- 

 mis, apice bifidis, segmentis acutis. 



"At Cromaglown, at Glenflesk, and in the mountains, co. Kerry." 

 Closely allied to J. tridenticulata {Taylor, MSS.). 



3. Jung, tricrenata, Wahl. " Caule erecto, subramoso, caespitoso, 

 flagella demittente ; foliis patentibus, ex lata basi ovatis, acutis, apice 

 bifidis, integrisve, convexis, subimbricatis ; stipulis minutis obovato- 

 rotundatis, subintegris ; fructu axillari ; calycibus lineari-oblongis, 

 acuminatis, ore quadripartito.
