1893, Davidson. All these localities are on the north slope of the San Ber- 
nardino range. The specimens from Holcomb valley are not as thrifty 
as the type; the flowers are somewhat smaller and the leaves (all under 7°) 
are principally from the base, leaving the long internodes exposed. The 
type is in the Herbarium of the University of California. 
This plant has been confused with Frasera nitida Benth., but it differs 
from that more northern species in the more open inflorescence, the more 
slender and acuminate leaves and bracts, and above all by the absence of the 
petaline gland, which in F. nétida is narrowly oblong and open for its whole 
length. The nectary in the proposed species is a pocket-like organ inserted 
within the tissues of the lower part of the petal, the opening surrounded by a 
narrow flap with ciliate margin. The raised tissues over the lower part of 
the nectary are ordinarily brown in color.

ASCLEPIAS CALiForNIcA Greene, Erythea 1:92. <Acerates 
tomentosa Torr. Two well-marked forms of this species are 
found in Southern California. In the more common form the 
leaves are broadly ovate and distinctly petioled, while the pedi- 
cels are short. The extreme of this form comes from Lytle 
creek caiion, altitude 1830", and has leaves 5-6.2™ wide by 
7-6™ long, while the pedicels are all under 2 in length. 
The second form has oblong-lanceolate slenderly acuminate 
sessile leaves and elongated pedicels. The extreme of this form 
was collected along the Temecula river and has leaves 5™ wide 
by 15°" long, while the spreading pedicels are 3™ in length. , 
That these forms do not deserve even varietal rank is shown 
by the fact that many intermediate forms exist, and one may 
pass from one extreme to the other by merely ascending a few 
thousand meters on some of the mountain slopes. AtgI4 a 
in Cajon pass the slender-leaved form prevails, while in passing 
up the mountains west of the pass various forms are encountered 
until the extreme of the broad-leaved form is met at 1830 meters. 
Gilia modesta, n. sp.—Plant annual, 15° high or less, divari- 
cately branching from near the base, the branches ascending, 
either glabrous or sparingly pubescent: leaves mostly oppo: 
below, the upper alternate, 1°™ long, palmately 3-7 -divided
