Eulobus. ONAGRACEJC. 221 



Var. foliosum, Torr. & Gry. Leaves linear-spatulate, nearly glabrous, with 

 smaller ones fascicled in the axils : petals nearly white. Fl. i. 490. 



Napa Valley and Knight's Ferry (Bigelow) ; Geysers (Greene) ; dry woods near Ukiah (Bolan- 

 dcr) ; and northward to Oregon. Guadalupe Island, Palmer. 



5. GAYOPHYTUM, A. Juss. 



Calyx-tube not produced above the ovary ; the 4-parted deciduous limb reflexed. 

 Petals 4, white or rose-colored, very small, obovate or oval with a very short claw. 

 Stamens 8 ; anthers broad or rounded, attached by the middle, those opposite to the 

 petals on shorter filaments and usually sterile. Ovary 2-celled : style short : stigma 

 capitate or clavate. Capsule membranaceous, clavate, 2-celled, 4-valved. Seeds 

 few to many, in one row in each cell, small, smooth, oblong, naked, ascending. 

 Very slender branching annuals, of western North America and Chili, with alter- 

 nate linear entire leaves and axillary flowers. The following are the only North 

 American species. 



1. Gr. ramosissimum, Torr. & Gray. Glabrous or the inflorescence sometimes 

 puberulent, diffusely much branched, 6 to 18 inches high : leaves an inch long or 

 less : flowers half a line long, mostly near the ends of the branches : capsule oblong, 



2 or 3 lines long, on pedicels of about the same length or shorter, often deflexed, 



3 - 5-seeded. Fl. i. 513 ; Watson, Bot. King Eep. 105. 



From Oregon to Mariposa Co. and eastward to Colorado, in the mountains on dry slopes. 



2. Gr. racemosum, Torr. & Gray, 1. c. Glabrous or more or less canescent with 

 short appressed pubescence, 6 to 18 inches high, the elongated branches mostly 

 simple : flowers half a line long, axillary the whole length of the branches : capsules 

 linear, sessile or very shortly pedicelled, 8 to 10 lines long, usually many-seeded. 

 Watson, 1. c. G. Nuttallii and G. ccesium, Torr. & Gray, 1. c. 



From the Columbia River to Central California and eastward to Colorado. 



3. G. diffusum, Torr. & Gray, 1. c. Nearly glabrous, 6 to 18 inches high : 

 flowers larger, 1 ^ to 3 lines broad, mostly toward the ends of the branches : capsules 

 3 to 6 lines long, a little exceeding the pedicels, often deflexed, the cells 4 - 8-seeded. 

 Watson, 1. c. 



Less frequent ; from Oregon to Southern California and eastward to Idaho and N. Utah. 



6. EULOBUS, Nutt. 



Calyx-tube scarcely at all produced beyond the ovary; the 4-parted limb reflexed. 

 Petals 4, rhombic-ovate, sessile, light yellow turning to red. Stamens 8 ; anthers 

 oblong, attached near the middle ; the filaments opposite to the petals much shorter 

 and with smaller globose anthers. Ovary 4-celled : stigma capitate. Capsule 

 linear, elongated, 4-angled, 4-valved, imperfectly 4-celled, strongly refracted. Seeds 

 very many, obovate-oblong, naked, erect. A smooth erect annual, with somewhat 

 of the habit of some species of (Enothera Chylismia; leaves few, alternate; flowers 

 sessile along the virgate branches. A single species. 



1. E. Californicus, Xutt. Stem 1 to 3 feet high, rather stout, with a few 

 spreading virgate branches : leaves linear, 1 to 2 inches long, sinuately pinnatifid 

 with numerous short unequal divaricate acute teeth : calyx-tube prolonged less than 

 half a line above the ovary : petals 4 or 5 lines long, the flowers rather showy : 

 capsules 3 or 4 inches long : seeds smooth, 3-angled, two thirds of a line long. 

 Torr. & Gray, Fl. i. 515.
