4a. Quamoclidion froebelii glabratum Standley, subsp. nov. 
Stems glabrous or almost so throughout, the younger branches sometimes 
sparingly puberulent; leaf blades broadly ovate or subreniform, 8 em. long and 
as broad’ or less, broadly rounded at the apex or obtuse, cordate or semi- 
cordate at the base, the blades slightly decurrent on the petioles, these one-third 
as long as the blades or less: peduncles about 3 em. long, stout: bracts 3 om. 
long, acutish or obtuse, sometimes mucronate, broad, glibrous; flowers about 
oem. long; fruit broadly elliptical or oval in outline, about 8S mm. long and 6 
mm. wide, light reddish brown marked by 10 black, vertical lines. 
The subspecies is separated from the species by its different pubescence and 
more obtuse leaves. Type in the herbarium of the University of California, 
collected in the Providence Mountains, California, May 25, 1902, Brandegcee.

8. HESPERONIA Standley. 
Hesperonia Standley, gen, nov. 
Mirabilis of various authors, in part, not L. 
Quamoclidion Rydb. Bull, Torr, Club 29: 686, in part; not Choisy. 
Perennial herbs; leaves opposite, thick, entire, petioled or sessile; inflorescence 
axillary or terminal; involucres campanulate, composed of 5 bracts which are 
united by their bases for about half their length, not enlarged in fruit: flowers 
1 in each involucre; perianth campanulate, white or purplish red: stamens 
usually 5, distinet; fruit ellipsoidal or spherical, not angled or ribbed, smooth 
or sometimes very faintly tuberculate, glabrous, 
The plants of this proposed genus have been variously placed in Mirabilis, 
Quamoclidion, and Oxybaphus, to all of which the genus is closely related, 
But besides differing considerably from all those genera in general appearance, 
Hesperonia is separated from Allionia and Mirabilis by the form of the 
fruit, differs decidedly from Mirabilis and Quamoclidion in the shape of the 
perianth, and is separated at once from Quamoclidion by the number of flowers 
in the involucre, 
Type species, Mirabilis californica A. Gray.
