Geayia^ POLYGALOiDES, H. & A. {Q. spiuosa, Moq. DC. Proar. 13. 2. 



119.) Erect, diiFusely branched, 1-3° high, the branchlets frequently spiny 

 at the apex ; leaves spatulate or obovate, 6-15" long, 2-5" broad, attenuate 

 at base into a short petiole, somewhat farinaceous or scurfy, and rather fleshy ; 

 flowering spikes J-1' long, the staminate flowers small, the fertile spikes 

 elongating in fruit and the calyx becoming 3-6', in diameter, white or pur- 

 plish, strongly compressed; fruit minute, rarely §" broad, nearly central in 

 the calyx. — From Southwestern Wyoming and Utah to Washington Terri- 

 tory and Oregon, Nevada, and Southeastern California. Frequent in alkaline 

 valleys and on dry foot-hills throughout the Great Basin ; 4-6,500 feet 

 altitude ; May -July. (989.) 



EuEOTiA* LANATA, Moq. DC. Prodr. 13. 2. 121. White-tomentose, 

 6 18' high, woody below, the subherbaceous branches virgate and often sim- 

 ple ; leaves numerous, alternate and fascicled, linear-lanceolate, 6-18" long, 

 1-2" wide, revolute upon the margins ; flowers frequently dioecious ; fruiting 

 involucre 2-3" long, penicillate with four dense tufts of long white hairs, 

 (becoming brown in the herbarium, as also the tomentum ;) seed minute, i" 

 long. — Scarcely diiFering from narrow-leaved forms of the Asiatic E. ceratoides. 

 From the Saskatchewan and Western Dakota to New Mexico, and westward 

 to the Sierras. Frequent in the dry valleys and ridges of Nevada and West- 

 ern Utah, retaining its foliage and fruit through winter, and valuable for 

 its fattening qualities for stock. Beef thus fed, however, acquires a peculiar 

 rather disagreeable flavor. Known both as "White Sage'' and "Winter 



1 GEAYIA, H. & A. Flowers dicacious, braotless, glomerate-spioate. Staminate flowers with a 

 5-parted unappendaged calyx, the five stamens inserted upon the receptacle, with linear-subulate fila- 

 ments and elliptic anthers. Calyx of pistillate flowers rounded-saccate, strongly compressed, winged on 

 the margins, emarginate at the contracted mouth. Ovary sessile, narrow-ohlong. Stylo slender-subu- 

 late, jointed at base. Stigmas 2, filiform, exserted, hirsute. Fruit included in the enlarged membranous 

 net-veined calyx, compressed, orbicular. Seed flattened, rounded, vertical, with a thin adherent peri- 

 carp. Albumen central, mealy. Embryo nearly annular; radicle inferior.— A somewhat spiuescent 

 undershrub, with alternate or fascicled entire and subsessile leaves, the flowers in axillary clusters, 

 forming terminal spikes. MoQura, in DC. Prodr. 



'^ EUEOTIA, Adajn's. Flowers monojcious or sometimes dioecious ; the staminate flowers glomerate- 

 spicate at the extremities of the leafy branches ; the pistillate below them, axillary, sessile, solitary or 

 clustered, S-bracted ; bracts at first free, becoming connate, enlarging and including the flower in a calyx- 

 like tubular involucre, the free summits elongated and narrowed. Calyx of the staminate flowers 4- 

 parted, the lobes ectual, membranous. Stamens 4, inserted on a naked receptacle. Fertile flowers with- 

 out calyx, staminodia, or nectariferous disk. Ovary ovoid. Styles 2, capillary, united only at the base, 

 exserted, hirsute. Fruit utricular, membranous, villous, included in the exceedingly hirsute involucre. 

 Seed vertical, compressed, obovate, with a simple membranous testa. Embryo nearly annular, surround- 

 ing the small mealy albumen, green ; radicle inferior.— Low stellately pubescent undershrubs, with 

 alternate short-petioled entire leaves. Ledebour, in Flor. Uo^s,
