confounded the two species, which is extremely probable, 
yet the old garden plant should be taken as that which 
he more particularly intended to describe. 
The names given by the American Gardeners to this 
species, such as Lewis's Scarlet Currant, Lewis's Yellow 
Currant, seem to attest its origin, and make it probable 
that it had been raised from seeds collected in Lewis and 
Clarke's expedition. This is rendered still more credible 
by its being the species found by Mr. Douglas in North- 
west America, if we may judge from the specimens in his 
Herbarium, and from plants in the Horticultural Society's 
Garden, raised from his seeds. This being the case, the 
remarks made by us in the Horticultural Transactions, upon 
Mr. Douglas's authority, concerning the excellent quality of 
the fruit of Ribes aureum when growing ‘ upon high dry 
limestone rocks,” should be applied to Ribes tenuiflorum. 
Upon further examination of the supposed variety of 
this species, the leaves of which change to scarlet in the 
autumn, we now incline to refer it rather to R. aureum, if, 
indeed, it be not a species by itself. 
About the same time as M. Colla published his ob- 
servations on this species, we had introduced it into a report 
made to the Horticultural Society upon the rare plants of 
their Garden; from which communication we take the 
liberty of making the following extract : — 
“ [n 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.— 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 flowers are not more than half the size of those of 
R. aureum, and have entire, not notched petals. The fruit 
is the size of the Red Currant, with a thick skin, and a 
dense mucilaginous pulp, of an agreeable flavour, but pos- 
sessing little acidity, and far inferior to our cultivated 
Currants. The berries ripen about the middle of July. 
** There are two varieties, the one bearing black, and 
the other yellow, fruit; the former changes from yellow to 
red, and finally acquires a deep blackish purple hue; 
the latter always retains its yellow colour."
