nearly to the base into rigid linear pungent-tipped lobes, these 
with strong midribs: flowers disposed singly or in pairs in the 
forks where they are short pedicellate, and clustered at the ends 
of the branches where they may be either sessile or short 
pediceled: bracts similar to the leaves but lobes usually only 
three, sparingly beset with loose cobwebby hairs: calyx pubes- 
cent, 8-11™" long, about equaling the bracts, cylindrical with 
acute base, hyaline membranous with green ribs prolonged 
beyond the hyaline portion into pungent-tipped nearly equal 
lobes which are 2™ or so long: corolla white, with the tube and 
throat yellow and with two purple lines at the base of each lobe; 
tube short; throat funnelform, 6-8™™ long, nearly equaled by 
the broadly obovate spreading lobes: stamens equally inserted 
near the base of the corolla tube, unequal in length, included: 
ovules in each cell 2 or 3; seeds oblong, developing spiracles 
only sparingly when wetted. 
Gravelly hillsides of Lytle creek cafion along the trail to San Antonio 
peak, altitude 1830™, June 1, 1900, 1443 Ha// (type); Swarthout cafion, San 
Antonio mountains, altitude 2000", June 3, 1900; near Bear valley, San 
Bernardino mountains, altitude 2000", July 16, 1899. The type is in the 
Herbarium of the University of California. 
This species is most nearly related to Gi/ia demissa Gray, but is easily 
distinguished from that by a number of important characters. G. modesta is 
a much larger plant, with a corolla fully 13™™ long, and nearly as wide when 
expanded, while G. demissa has a corolla only 6.5" long. The proposed 
species has a calyx of 5 narrow green ribs of equal width throughout, between 
which is stretched a hyaline membrane connecting them for three fourths their 
length, while G. demissa has a calyx of 5 lanceolate nearly distinct segments 
each with a scarious margin. The lobes of the leaves and bracts are more 
slender and rigid than in G. demissa, and the ovules are never more than 
three in each cell, as against seven in G. demissa. From G. Parry@ Gray it 
differs in many respects, principally in the absence of scales at the base of the 
corolla lobes. The general appearance suggests relationship with the mem- 
bers of the Linanthus section, but it differs from all those in the pubescence, 
in the funnelform corolla, in the small mumber of ovules, and in other 
characters.
