70 PITTONIA. 
Shrub with the aspect of R. Menziesii from which it is 
readily distinguished by the solitary deciduous bract which, 
until it falls away, enfolds the ovary. The proportions of 
tube and limb of the calyx are no less distinctive, the former 
being long, cylindrical and 10-striate. I am obliged to admit, 
as forms of one species, the almost hoary shrub of the Garber- 
ville region and the nearly glabrous one of the district farther 
north. This kind of variability is somewhat common on this 
coast, among the species of Ribes. My R. velutinum (Bull. 
Cal. Acad. i. 83), which, as I know it in northern California, is 
covered all over, even to the fruit, with an almost velvety 
pubescence, I now have from Mr. Cusick, of northern Oregon, 
in a perfectly glabrous state. 
AENOTHERA (SPHROSTIGMA) NITIDA. Biennial or perhaps 
perennial, the rigid stoutish wiry branches decumbent or 
prostrate, 3—1 foot long: leaves spatulate or oblanceolate, 
petiolate-narrowed, obtuse, entire, somewhat fleshy, glabrous, 
dark green and with a shining surface: flowers axillary, ses- 
sile ; corolla an inch broad, yellow, fading green : capsule 10 
lines long, coriaceous, smooth and shining, sharply quad- 
rangular, gradually narrower above, strongly falcate-incurved : 
seed black, ovate, acute at base, compressed, smooth but dull, 
not shining. 
Island of San Miguel, on the higher northern portion, 
growing with Æ. cheiranthifolia to which it is related. The 
dark shining foliage appears coriaceous when fresh, yet in 
drying comes down to the membranaceous. 
ONICUS AMPLIFOLIUS. Herbage somewhat fleshy, green and 
glabrous except a sparse and minute arachnoid tomentum on 
the lower face of the leaves: stem stout, 3—4 feet high : 
leaves very ample, with crowded and imbricated, trifid, 
Spinose-ciliate lobes, deeurrent: heads clustered, an inch or 
more high, bracteose-leafy at base, the outer involucral scales 
loosely spreading and arachnoid, the inner appressed and
