Only two other species are known, belonging to Asia and Soutliern Europe. 

 1. E. lanata, Moquin. AYhite-tomentose throughout (becoming rufous), a span 

 or two higii, woody below, wdth strict ascending leafy branches : leaves linear to 

 narrowly lanceolate, obtuse, |- to \^ inches long, margins revolute : calyx-lobes ovate, 

 acute, hairy : fruiting bracts lanceolate, 2 or 3 lines long, nearly covered by 4 dense 

 spreading tufts of long silvery-white hairs, and beaked above with two short erect 

 horns : utricle filling the cavity and loosely enveloping the seed, which is 1^ lines 

 long. —DC. Prodr. xiiil 121 ; Watson, Eev. Chenop. 121. 



In subalkaline soils eastward of the Sierra Nevada from Oregon to the Saskatchewan, and south- 

 ward to Nevada and New Mexico. Abundant in some valleys and valuable as a winter forage 

 plant ; usually known as " White Sage," or " Winter Fat," and of good repute as a remedy for 

 intermittents.

riowers dioecious or sometimes moncecious. Staminate flowers without bracts : 

 calyx mostly 4-parted : stamens 4 or 5, with short subulate filaments. Pistillate 

 flowers bibracteate, without perianth. Bracts membranous, strongly obcompressed

 fruit, net-veined and wing-margined. Styles 2. Pericarp thin and membranous. 

 Seed vertical, orbicular, with thin membranous testa. Ptadicle inferior. — Slightly 

 scurfy or mealy undershrubs ; leaves alternate, entire ; flowers small, in axillary 

 clusters or terminal spikes. Only the following species. 



1. Gr. polygaloides, Hook. & Arn. Erect, diffusely branched, 1 to 3 feet 

 high, the hramhcs tivpicntly spinescent : leaves glabrous or at first with the young 

 bi'anches somewhat mealy, rather fleshy, oblanceolate or spatulate to obovate, 6 to 

 15 lines long, obtuse or acute, narrowed at base and sometimes petioled : staminate 

 flowers in axillary clusters ; the pistillate mostly si)icate : fruiting bracts 3 to 6 lines 

 in diameter, sessile, glabrous, emarginate, thin, white or pinkish, adherent below to 

 the pedicel of the ovary : styles slender, at first exserted : seed nearly central, 

 about f line broad. — Bot. Beechey, 387; Hook. Icones, t. 271; Watson, Eev.

 Utah and Southeastern California. 



O. RiJANDEOEi, Gray, Proc. Am. Acad. xi. 101, of S. W. Colorado, is lower and unarmed, 

 more mealv, with linear-spatulate leaves ; fruit smaller (3 lines broad), slightly mealy, retuse at 

 base, sometimes 3-winged ; wings somewhat undulate ; ovary sessile ; style short, included. 



10. CORISPERMUM, Ant. Jussieu. Bug-seed. 

 Flowers perfect, witliout bracts. Perianth of a single hyaline ovate or rounded
