516 Account of some new Species of the Genus Ribes. 



A common bush on the banks of streams near Indian vil- 

 lages, on the North West Coast of America, from the 45° to 

 the 52° N. Lat. 



This species flowered last April in the Horticultural So- 

 ciety's Garden. It ranks systematically next the R. triflo- 

 rum of Willdenow. 



6. R. irriguum ; aculeis axillaribus ternis, foliis cordatis sub-5-lobis dentatis 

 ciliatis utrinque pilosis nervosis, pedunculis 3-floris glanduloso-pilosis, calycibus 

 campanulatis : laciniis linearibus tubum sequantibus, baccis glabris. 



A tall strong species, sometimes ten feet high, branching, 

 nearly smooth, except having three small sharp, ascending 

 short prickles below each bud ; bark white. The leaves are 

 deeply cordate, three or imperfectly five-lobed, coarsely 

 toothed, pubescent on both sides and ciliated on the margins, 

 veiny, about an inch and a half long, somewhat shorter than 

 the footstalks. The flowers are bell-shaped, in clusters of 

 three, which are shorter than the leaves, its calyx having 

 linear segments which equal the tube in length, and oblong 

 petals, half as long as the limb. The berries are spherical, 

 half an inch in diameter, smooth, juicy, with a very pleasant 

 flavour. 



A constant inhabitant of moist mountain rocks, near springs 

 and streams, flowering in May and ripening its fruit in July. 

 On the Blue Mountains in 46° 33' it is very common ; also 

 on hills on the banks of Spokan River. 



Of all the species which came under my observation during 

 my journies in America this is the finest in the flavour of its 

 berries, as well as in their size. It has not yet flowered in 

 the Society's Garden.
