CORISPERM UM 
dioecious or sometimes monoecious. Calyx ofthe bractless stamin- 
ate flowers mostly 4-parted, the 4-5 stamens central, with short 
subulate filaments. Pistillate flowers without calyx, enveloped 
in the obcompressed membranaceous bracts which are united into 
an orbicular flattened sac with a small naked orifice at the apex, 
adherent below to each other and to the pedicel of the ovary, be- 
coming enlarged and reticulately veined and somewhat wavy- 
margined vertically. Styles 2, slender, at first exserted. Seeds 
vertical, with a membranaceous testa. Embryo annular: radicle 
inferior. 
E. spinosa Greene Pitt. iv. 225 Grayia polygaloides H. & A. Stems 
erect, diffusely branched, 1-4 feet high, the branchlets often spines- 
cent: leaves rather fleshy, glabrous or at first with the young branches 
somewhat mealy, oblanceolate or spatulate to obovate, 6-15 ies long, 
obtuse or acute, narrowed at base and sometimes petioled: staminate flow- 
ers in axillary clusters, the pistillate mostly spicate: fruiting bracts 3-6 
lines in diameter, sessile, smooth, emarginate, thin, white or pinkish: the 
seed usually central, about 24 of a line broad. On rocky ridges, eastern 
Oregon to California and Utah. 
Tribe 3 Corispermex Mog. Chenop. 101. Stems not articulated. 
Leaves not fleshy. Flowers perfect, bractless. Pericarp adherent to 
the vertical seed. Embryo annular around copious albumen. 
9 CORISPERMUM L. Sp. 4. 
Annual herbs with alternate leaves and small perfect bractless 
green flowers solitary in the axils, forming narrow leafy terminal 
spikes, the upper leaves shorter and broader than the lower. Calyx 
lor 2thin broad sepals. Stamens 1-3, rarely more and one of 
them longer. Ovary ovoid: styles 2. Utricle ellipsoidal, mostly 
plano-convex, the pericarp firmly adherent to the vertical seed, 
its margins acute or winged. Embryo annular, surrounding 
somewhat fleshy albumen: radicle inferior. | 
C. hyssopifolium L. Sp. 4. More or less floccose or villous-pubescent : 
stem erect, 6-18 inches high, diffusely much branched: leaves linear, 9-18 
lines long, cuspidate: floral bracts reduced more or less abruptly, from 
linear-lanceolate to ovate, acute to acuminate, membranously margined: 
sepals rarely wanting, shorter than the bracts: stamens more or less per- 
fectly developed: fruit 144-2 lines long narrowly winged, obtuse, often 
mucronate with the projecting style. On sandy alkaline plains, Alaska to 
California and the Atlantic States and Europe. 
Tribe 4 Salicorniex Dumort. Moq. in DC. Prodr. xiit pt. 2, 144. 
Fleshy saline plants with jointed stems and scale-like leaves. Flow- 
ers mostly perfect, immersed bi threes in depressions in the rachis of a 
close cylindrical spike. Seed vertical. Embryo annular, with little 
albumen. 
9 SALICORNIA L. Sp. 3. 
Fleshy annual or perennial plants with opposite terete branches 
scale-like leaves and small perfect, or the lateral staminate, flow- 
ers in heads of 3-7 sunken in the axils of the upper scales, form-
