BOTANY. 147 
Mexico, Chihuahua and Sonora; flowering throughout the spring and summer. (No. 509, 
1648 and 1649, Wright.)

GILIA DICHOTOMA, Benth. 1. с. Var. PARVIFLORA : floribus multo minoribus ; corollis inexpansis. 
Cook's spring, and near Frontera, Texas, March—April; Bigelow, Wright. About 6 inches 
high. Leaves palmately 3-parted to the base; segments subulate and somewhat rigid. Corolla 
much smaller than in the Californian plant, and it does not seem to expand. In other respects 
I can find nothing to distinguish it. There are from 20 to 25 ovules in each cell of the ovary. 
GILIA PHARNACEOIDES, Benth. 1. c. Near the summit of the mountains east of San Diego,

GILIA DENSIFLORA, Benth. 1. c. Grassy places near Monterey, California; Parry. Not 
sufficiently distinct from G. grandiflora. 
GILIA CALIFORNICA, Benth. l. c. Leptodactylon Californicum, Hook. & Arn. Bot. Beech. p. 
369, t. 89. Near Santa Barbara, California; Parry. This species is decidedly shrubby. Dr, 
Antisell found it growing at Santa Inez, 3-5 feet high. 
PoLEMONIUM c@RULEUM, Linn.; Hook. Fl. Bor.-Amer. 2, p. 11. Banks of the Mimbres, New 
Mexico, October, (in fruit); Bigelow. Stem 3 feet high, and, as well as the leaves glabrous. 
Segments of the leaves 17-21, lanceolate, acute, about an inch long. We find among our 
numerous specimens of this polymorphous species, some that accord very well with our New 
Mexican plant.

Parry. Neuvo Leon; Dr. Edwards. Dr. Gregg found it near Saltillo, Coahuila. 
NAMA DICHOTOMA, Choisy, Desc. Hydrol. p. 19; & in DC. Prodr. 10, p. 182. Sandy prairies 
and along water courses, western Texas and New Mexico from Doña Ana to the Gulf, and west- 
ward throughout the Mexican States to Sonora and California, (No. 495, 1585 and 1586, 
Wright.) Very much branched, spreading or assurgent. Flowers pale purple, з, yellowish in 
the throat. Our plant resembles a Chilian specimen of N. dichotoma received from Dr. Arnott 
(which is part flowering), but differs from the description of Choisy in the corolla being half as 
long again as the calyx. 
Var. PARVIFOLIA: caule tenui laxiuscule ramoso ; foliis (semiuncialibus) obovatis obtusis basi 
in petiolum brevem attenuatis; floribus solitariis geminisque, pedicellis calyce dimidio longiori- 
bus. Santa Rosa, Chihuahua, January; Bigelow. Monterey, Neuvo Leon; Dr. Edwards and 
Major Eaton. Annual. Stem very slender, dichotomously branching, purplish. Lower leaves 
about half an inch long, abruptly narrowed at the base into a petiole which is less than half 
the lamina; upper leaves 3-5 lines long. Flowers nearly as in the larger variety.
