Sierra Nevada. Examples from Dunlap, in Fresno County, col- 
lected by Mrs. Sophie E. Wilson, are rather small-flowered and of 
a deep rose color; the manifold gland nearer the base of the seg- 
ments than usual. 
This form is probably C. amenus Greene, from the mountains east 
of Visalia. The author describes it by comparison with C. pul- 
chellus and says, ‘‘ petals more elongated, the ciliation longer, more 
lax and scarcely carried above the middle of the organ, the whole 
flower of a deep red-purple.” This is a fairly good description of 
C. albus, as far as it goes (the author makes no mention of the 
gland), but it is difficult to understand why he compares it with C. 
pulchellus. In differential diagnosis, species are usually supposed to 
be compared with the nearest, but the author who is somewhat 
celebrated for ‘‘new departures’’ wishes perhaps to establish a pre- 
cedent. 
Sco.iopus BIGELovi Torr. Very abundant in the Coast Range 
from Santa Cruz to Oregon and sufficiently conspicuous with its 
pair (sometimes three or four) of spotted, usually prostrate leaves. 
The flowers on account of their dull color and early appearance are 
less frequently collected than those of many less abundant plants. 
About Tamalpais they are to be found on damp and shady hillsides 
early in February. 
The pedicels 2-8 inches long are triquetrous and somewhat winged 
on the angles, at first erect, elongating and becoming tortuous in 
fruit, and trying usually with success to hide their capsules under 
the leaves. The outer segments of the lurid purplish perianth are 
concave, thickened and shining at base. The connective’ of the 
extrorse anthers is much thickened especially at the upper part. 
The style branches though deeply sulcate their whole length are 
‘stigmatic only at the recurved apices, which in the young flower 
_ bend over touching the outer surface of the stamens. The capsules 
open by irregular fissures between the placentiferous angles which 
remain for some time attached at base and apex, forming a kind of 
framework from which the tissue falls away in minute scales—ap- 
parently disintegrating into its separate cells. The turgid seeds are 
3-4 mm. long, pale in color, and minutely pubescent, the inner seed 
coat is deficient at the apex and the opening is plugged with a 
disk of soft tissue somewhat darker in color than the seed, and 
in drying shrinks forming a depression. The longitudinal lines
