lected very early in the season, and the more advanced state of the plant is doubtless consider- 
ably taller and more branching. 
Gira VIRGATA, Steud. Nom.; Benth. 1. с. p. 311. Monterey, California; Parry. This species 
is certainly an annual.

GILIA POLYCLADON (n. sp.): caulibus plurimis subpatulis puberulis inferne nudiusculis apice 
foliosis cymoso-capitatis ; foliis oblongis hirsutis pinnatifido-incisis segmentis oblongis plerumque 
integris vel 1-2-dentatis ; calycis dentibus spinuloso-acuminatis; corolle tubo calyce subsequali, 
laciniis oblongis; loculis ovarii biovulatis. Stony hills near El Paso, March. Annual, stems 
4—8 from one root, slender terete, somewhat spreading, simple and mostly naked, except at the 
summit, where they branch into a leafy cymose tuft. Leaves mostly radical, about an inch 
long, pinnately cut into 9-11 oblong spreading lobes, which are mostly simple. The leaves 
of the stem are similar to the radical, only they are smaller.  Fructiferous calyx as long as the 
capsule. Corolla white, with a tinge of rose-color. Allied to G. inconspicua. 
GiLtA ACHILLEXFOLIA, Benth. l. c. 311. San Isabel, California, Мау; Thurber. 
GILIA CAPITATA, Dougl. in Dot. Mag. t. 2698; Benth. 1. с. Common in most parts of Cali- 
fornia, from Oregon to San Diego, usually not fár from the coast. 
GHIIA MULTICAULIS, Benth. l. c. Near San Diego, March; Parry. Perhaps only a variety of 
the last.

fornia. 
GILIA INCISA, Benth. l. c. p. 312. Central and western Texas to the Rio Grande, also in New 
Mexico, Chihuahua, and Neuvo Leon. Plant 12-18 inches high. It appears to be both 
annualand biennial. Flowers white. The radical leaves often form a cluster, and are much 
less cut than the stem leaves. 
Gitta RIGIDULA, Benth, 1. c. Hill sides and rocky ravines, western Texas, New Mexico, and 
Sonora, March—May. (No. 1645, Wright.) Perennial. Plant 4-10 inches high, branching 
from the base, viscidly pubescent or almost glabrous. Leaves mostly simply pinnatifid, with. 
5-1 distant rigid and pungent segments, which vary from oblong-lanceolate to very narrowly 
linear. The flowers are nearly three-fourths of an inch in diameter. Corolla bright blue, 
yellow in the throat. Cells of the ovary with several ovules. 
Guia MULTIFLORA, Nutt. Pl. Gamb. in Journ. Acad. Phil. (n. ser.) 1, р. 154. Hill sides near 
the Copper Mines, New Mexico, August; Bigelow. Sonora and Chihuahua, September; Schott. 
(Nos. 1646 and 1647, Wright: the latter with the tube of the corolla lon ger.) The stem rarely 
branches from near the root, except when the top has been injured.
