242 Report upon New or Rare Plants, fyc. 



R. aureum, uprcecox; floribus praecocibus, foliis basi cuneatis subtus pubescen- 

 tibus : lobis grosse inciso-serratis, baccis copiosis praecocibus turbinates, racemis 

 bracteatis. 



R. aureum, /3 serotinum ; floribus serotinis, foliis heteromorphis basi truncatis 

 subtus glabriusculis : lobis inciso-serratis, baccis raris serotinis sphasricis, racemis 



R. aureum, y sanguineum; floribus serotinis, foliis basi truncatis mox sangui- 

 neis, baccis copiosis sphaericis, racemis bracteatis. 



The plant to which allusion is above made, as a distinct spe- 

 cies confounded with R. aureum, was purchased by the Society 

 in 1824 from Mr. William Prince, of New T York, under the 

 name of Lewis's yellow fruited currant.* Of this 1 now pro- 

 ceed to give some account as 



XLVIII. Ribes tenuiflorum. 



R. inerme, foliis subrotundis trilobis farinosis mox glaberrimis cruentis : lobis 

 apice obtuse dentatis, racemis pendulis multifloris, calycibus tubulatis glabris pe- 

 dicello longioribus coloratis, petalis integerrimis calycis laciniis linearibus obtusis 

 duplo brevioribus, baccis glabris. 



In habit this species is more erect than R. aureum, and has 

 the young wood more thinly clothed with leaves : its whole 

 appearance is also paler during the early part of the year ; in 

 the autumn the foliage becomes deep crimson, and the bush ex- 

 tremely ornamental. The leaves are nearly round, 3-or 5-lobed, 

 when young covered with a kind of mealy bloom, when more 

 advanced cordate at the base, and at all times, in the plants 

 that I have examined, wholly destitute of pubescence. The 



* While this Paper was in the press, M. Colla's Third Appendix to his Cata- 

 logue of the Plants, cultivated in his garden at Ripuli, came to my hand. In this 

 work I find my R. aureum sanguineum considered a distinct species, and figured 

 (tab. I. fig. B.) under the name of R. flavum, and, what appears to be the plant 

 above-named R. tenuiflorum represented as the original type of R. aureum ; an
