a. Species or Varieties of Ribes belonging to the Subdivision A of the Section 

 Ribesia, which are not yet introduced. 



R.fragrans Pall. (Nov. Act. Pet., 5. p. 377. t. 9.) has the leaves glabrous, on long petioles ; and the 

 flowers campanulate, white, and sweet-scented. The berries are red, and of a very sweet taste ; and 

 from the under surface of the leaves exudes, in numerous little yellow drops, a very fragrant bal- 

 samic resin, having a strong smell of the black currant. 



R. heterdtrichmn Meyer in Led. Fl. Ross. Alt. 111., t. 235., Fl. Alt., 1. p. 270., has the stem erect- 

 ish, the leaves pubescent, nearly orbicular, 3-lobed ; and the racemes and flowers erect. The calyx is 

 of a livid purple colour, the petals purple, and the fruit like those of R. rubrnm, but orange-coloured. 

 It is a native of Altaia, on rocks at the foot of the mountains towards the river Kurtschum. 



R. bractebsum Dougl. (Don's Mill., 3. p. 186.) has the leaves on long petioles, and nearly as large 

 as those of the A'cer Pseudo-Platanus. The flowers are of a purplish yellow, and the fruit about the 

 size of that of R. rubrum. It is a native of the north-west coast of America, at the confluence of 

 the Columbia with the ocean, whence specimens were sent home by Mr. Douglas, from which a 

 description is given in Hooker's Flora Borealis Americana. 



R. tubiflbrum Meyer is a native of California, with cordate leaves, and spicate, terminal, drooping 

 racemes ; the flowers having tubular calyxes, exceeding the bracteas. 



R. tubulbsum Eschscholtz is a native of North California, with hoary, rigid, dark purple branches, 

 cordate 3-lobed leaves, and pale brown petals. It is considered as nearly allied to R. albinervium, 

 and also to R. sangufneum. 



R. macrobotrys Ruiz et Pav. Fl. Per., 3. p. 12. t. 202., Berl. in Mem. Phys. Gen., 3. pi. 2. t. 2. 

 f. 17., has cordate leaves, and very long pendulous racemes, rufescent calyxes, and greenish hairy 

 berries. It is a native of Peru, on the Andes, in groves. 



R. albiflbrum Ruiz et Pav. Fl. Per., 3. p. 12. t. 132. f. 6., Berl., 1. c, t. 2. f. 18., is a native of Peru, 

 and nearly allied to the preceding species. 



R. ciliatum Willd., R. jorulltinse H. B. et Kunth, has 5-lobed leaves, deeply cordate, and is also 

 nearly allied to R. macrobotrys. It is a native of Mexico, on the burning Mount Jorullo, at an ele- 

 vation of 1500 feet. 



R. Mr turn Thunb. et Bonpl., R. frigidum H. B. et Kunth, Berl, 1. c, t. 2. f. 13., has ovate-cordate 

 3-lobed leaves, flesh-coloured flowers, and hispid berries. It is a native of South America, in cold 

 places, on Mount Antisana, at an elevation of 300 ft. 



R. campanulatum Thunb. et Bonpl., R. affine H. B. et Kunth, has 5-lobed, crenated, cordate 

 leaves, and campanulate white flowers. It is a native of Mexico, near Moran, at an elevation of 

 3900 ft. 



R. Kiinthn Berl. ; R. multiflorum H. B. et Kunth, but not of Kit. ; is a native of Mexico; and is 

 generally found with R. campanulatum, which it closely resembles. 



R. Takare D. Bon Prod. Fl. Nep., p. 208., has cordate, 3-lobed, acuminated leaves, as large as those 

 of the common sycamore ; but the flowers have not been observed. 



R. acuminatum Wall., Royle Illust., p. 225., has glabrous branches, leaves 3— 5-lobed, and berries 

 about the size of red currants. It is a native of Nepal on Sirmore and Emodi, at elevations of 

 from 8000 ft. to 10,000 ft., where it grows to the height of 5 ft. or 6 ft. 



R. villbsum Wall, has pubescent branches, and nearly orbicular leaves, with erect few-flowered 

 racemes. It is a native of the Himalayas, in Sirinegur. 



B. Flowers greenish yellow y sometimes with the Tips of the Sepals and Petals

Spec. Char., $c. Leaves dotted from glands beneath, 3 — 5-lobed. Racemes 

 loose. Bracteas minute, subulate or obtuse, much shorter than the pe- 

 dicels. Petals oblong. Calyx campanulate, with reflexed segments. Flowers 

 whitish, or yellowish green. Calyx often of a rich brownish red colour, 



or pink. Stamens sometimes more than 5, in which case there are fewer 

 petals ; so that when there are 10 stamens there are no petals. This 

 change of petals into stamens is just the reverse of the process by which 

 single flowers become double; and it is the only fact of the kind which has
