in length, those of the branches smaller and narrower ; all thin, entire, or obscurely repand, 
loosely feather-veined. Flowers apparently purple, small, the lobes of the calyx and the petals 
about two lines long. Stamens apparently not declined; the four longer ones equaling the 
petals, and with very short basi-fixed anthers; the alternate ones (opposite the petals) much 
shorter, and with the anthers abortive. Style long ; stigma hemispherical, entire, or nearly so. 
Fruit globular-obovate, gibbous, obscurely ribbed, a line and a half long, indehiscent. This is 
the only Gaura yet known from California, and a very peculiar one, but apparently of this genus, 
notwithstanding the abortive shorter stamens and the short anthers of the others.

RIBES CALIFORNICUM, Hook, de Arn., R. Californicum, occidentale, and subvestitum, Hook. d 
Arn. Bot. Beech., p. 346; Torr. & Gray, Fl. 1, p. 545, 548. Dr. Bigelow’s specimens, with 
others, collated with those of Douglas, plainly show that the three above-mentioned nominal 
species must be reduced to one, which should stand next to R. Menziesii, (the anthers of which 
are slightly mucromate,) and for which the name of R. Californicum is to be preferred. The 
subaxillary spines are sometimes solitary, geminate and ternate on the same branch; the: 
branches are setose or naked on otherwise similar plants ; the foliage is either glabrous, glan- 
dular-pubescent beneath, or simply pubescent, and either moderately or deeply lobed and incised ; 
the flowers in all are reddish or purple; the ovary, etc., more or less strongly glandular and 
setose, and with or without a soft or hirsute pubescence. R. Californicum was founded on a 
small-leaved and smaller-flowered state of the species. R. subvestitum on a larger-leaved and 
large-flowered form. Dr. Bigelow’s collection comprises the following: 1. From rocky ravines, 
Cajon Pass; March 16: the R. subvestitum, Hook. & Arn., except that the branchlets are not 
setose, and the pubescence of the leaves scarcely glandular.—2. Mammoth Grove, on the pros- 
trate trunk of a huge Sequoia gigantea; May 11: similar to'the preceding, but the leaves more 
cleft, and the calyx-tube more pubescent.—3. Mountains near San Gabriel ; March 28: like No. 1, 
but more glabrous leaves, glandular-dotted beneath.—4. Duffield's ranch, Sierra Nevada, with 
young fruit, which is large, hairy, and prickly.—5. Grass valley ; May 20, with young fruit : 
the same, with glabrous leaves.—6. Duffield's Ranch, on hillsides, and near San Francisco : 
forms with the foliage and calyx, etc., perfectly glabrous; the fruit glandular and prickly. 
This answers to R. occidentale, but the subaxillary spines are often in pairs, threes, or fives. It 
is the same as Hartweg’s No. 1736.—Gray, Mss.

April 3. This accords entir:ly with the Californian plant of Douglas's collection, except that 
the racemes are 4—5-flowered. Nuttall's R. villosum is merely a pubescent form of it.
