 dina,Moq., DC. Prod., 13, 2d pt., p. 164.) Annual, herbaceous, prostrate, 

 very much branched, glabrous, often reddish; stems (3" -6" long) and 

 branches usually more or less flexuous ; leaves mostly flatter and 

 broader than i a the last; flowers and seed similar. Hall & Harbour,

SARCOBATUS 2 VERMICULATUS, Torr. (Fremontia vermicularis, Torr. 

 Frem.Rep., pp. 95 and 317, t. 3.) Erect, 3-G high, diffusely branched, more 

 or less spinose and the rigid divaricate or spreading branchlets spines- 

 cent at the extremities ; leaves G^-18" long, i"-2" wide, frequently much 

 smaller and fascicled on the branchlets, scurfy-pubarulent when young, 

 becoming glabrous ; staminate aments 3"-9" long, cylindrical or oblong, 

 nearly 2" in diameter ; anthers soon deciduous ; winged calyx of the 

 mature fruit 3"-G" broad; seed V in diameter, with a thin membranous 

 transparent testa. Near Canon City, Redfield. 



1 EUROTIA, Adans. Flowers monoecious or sometimes dioecious ; the staminate 

 flowers glomerate-spicate at the extremities of the leafy branches; the pistillate below 

 them; axillary, sessile, solitary or clustered, 2-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 

 equal, 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 ntricular, membranous, villous, included in 

 the exceedingly hirsute involucre. Seed vertical, compressed, obovate, with a simple 

 membranous testa. Embryo nearly annular, surrounding the small mealy albumen, 

 green; radicle inferior. Low stellately-pubescent uudershrubs, with alternate, short 

 petioled entire leaves. Ledebour in Flor. Ross. 



2 SARCOBATUS, Nees. Flowers unisexual, monoecious and dioecious. Staminate flowers 

 in terminal aments. Scales eccentrically peltate, stipate, angular, cuspidate. Stamens 

 2-4 under each scale, naked, sessile ; anthers oblong. Pistillate flowers solitary, axil- 

 lary. Calyx ovate, compressed, urceolate, contracted at the apex about the style and 

 somewhat bifid, enlarged and thickened in fruit and developing below the middle a 

 broad transverse undulate veined wing. Ovary sessile, very thin and membranous, 

 flattened, orbicular, mostly oblique, terminating laterally and abruptly in the slender 

 included persistent style; stigmas exserted, thick, divaricate, often unequal ; ovule on 

 a short funiculus, campylotropous. Seeds vertical, with a double integument ; embryo 

 flat-spiral, green ; radicle inferior ; albumen at the base very small or none. A spines- 

 cent shrub of alkaline soils, with alternate linear fleshy leaves.
