Dr. T. Bell Salter on some forms o/Rubus. 371 



In all its forms this is a most beautiful plant. It is one of 

 very elegant growth, while the lively green of the foliage, which 

 is veined with purple, and the bright red of the almost moss-like 

 clothing of glands, add much to its beauty of appearance. The 

 forms marked /8. and 7. are those published as distinct species, in 

 the account of " Three days' botanizing at Selborne,'' published 

 in the ' Phytologist'*. The discovery of the form yS. in the Isle 

 of Wight this year, and the opportunity of seeing the forms a. 

 and 7. growing together in St. John's Garden, have since enabled 

 me to become better acquainted with these plants. These two 

 last-named forms, now they are growing in the same situation, 

 have become considerably approximated, and I cannot longer do 

 otherwise than consider them as varieties of the same species, 

 while /9, which is the least glandulose, is in all other points the 

 connecting link. The distinctions made in the ' Phytologist ' are 

 still applicable to these as varieties ; I would add, however, that 

 the ^. of Selborne, having grown in the shade, was, as I then sup- 

 posed, deficient in vestiture. In all the varieties the leaves are 

 sometimes quinato-pedate — more often in /8. than the other forms, 

 but in this too it is the exception. The calyx is variable in all 

 the forms, both in respect to the amount of foliaceous appendix, 

 and also as to its direction, which is reflected or erecto-patent in 

 various degrees. 



The remaining two forms are those which constitute the spe- 

 cies appearing now for the first time as British. 



17. RuhmWahlbergii {h.vv\iQm\\&), — >S^^e?w arched, round. Prickles 

 numerous, with thick bases, very unequal, hairy. Hairs on the 

 stem and glands very few. Leaves quinato-digitate. Leaflets 

 subrotund, cordate acuminate, pale green beneath. Panicle 

 branched, leafy, tomentose and prickly. Prickles of the panicle 

 numerous, very strong and decurved. Calyx broadly ovate, to- 

 mentose and glandular, patent in fruit. Fruit of few large 

 grains.

This is a very remarkable plant, which has attracted my notice 

 for many years as one of very peculiar appearance. I had thought 

 it an undescribed one, until Mr. Babington pointed out to me 

 the description of Arrhenius in his excellent ' Monograph * under 



* Vol. ii. pp. 133-137.
