 are more deeply lobed than in the common red currant, and the lobes are 

 pointed. The fruit is roundish, flattened somewhat at the end, red. and

52710. RiBES ussuRiENSE Jancji. Grossulariaceie. Currant. 

 A much-branched shrub 1 millimeter high, producing rhizomes like 



those of Riles aureum; the shrub has an odor resembling that of 

 camphor. The glabrous leaves dotted below with yellow glands are 8 

 centimeters long and broad and three to five lobed. The loose arched 

 racemes, 1 to 1^ centimeters long, bear five to nine whitish flowers 

 briefly campanulate. The round fruit, as large as a currant, is black 

 (greenish blue before ripening), not aromatic, and with greenish, 

 slightly sweet acidulous flesh. The small ovoid seeds have a greenish 

 gelatinous coating and an inflated funiculus. The fruit falls as soon 

 as it is ripe and the seeds germinate in 22 to 50 days. The floral buds 

 are very sensitive to winter cold. (Adapted from Janczetoski, Mono-
