lous, nearly as much so as in R. canus, Benth. Pl. Hartw. 
No. 1626, from California; indeed, it would seem to belong 
to the same species; but the carpels are, as in our &. repens, 
pointed with a pretty long, straight, or flexuous beak, slen- 
derly subulate from a broad base, and not ‘“‘mucrone valde 
recurvo fere circinnato,”’ as #. canus is characterized. My 
specimen of the latter exhibits no fruit. The petals are in 
some specimens nearly an inch in length; in others no larger - 
than in ordinary American forms of R. repens, into which it 
passes by every kind of gradation.

&c. (575.) An evergreen shrub, with few branches, but 
with many stems from the same base, often forming large 
thickets. It flowers in February and March; and the yellow 
blossoms exhale the odor of saflron. The globose berries, 
about the size of peas, ripen in May, are red, aromatic, and. 
acid; they are called “currants” by the inhabitants, and are 
used for tarts, &c. This interesting species, which is 
remarkable for its palmately trifoliolate leaves, is first men- 
tioned in the Appendix to the first volume of the Flora of 
N. America, as having been gathered by Drummond with- 
out flower or fruit. In 1841, it was named and characterized
