CHENOPODIACEAE. 375 



About 10 species, natives of the north temperate and subarctic zones. Only the 

 following is known to occur in N. Am. 



Upper leaves imbricated; fruit 3.5-5 mm. long. i. C. hyssopifolium. 



Upper leaves not imbricated ; fruit 2 mm. long. 2. C. nitidum. 



1. Corispermum hyssopifolium L. BUG-SEED. (I. F. f. 1388.) Rather 

 pale green, somewhat pubescent when young, fleshy ; stem erect, 1.5-4 dm. tall, 

 the branches slender, ascending or divergent. Leaves narrowly linear, sessile, 

 1-5 cm. long, 2-4 mm. wide, cuspidate, the upper ovate or lanceolate, imbricated, 

 appressed-ascending, or at length spreading, acute or acuminate, 6-12 mm. long, 

 scarious-margined; utricle 3.5-5 mm. long, winged. In sandy soil, shores of the 

 Great Lakes to the N. W. Terr., Arctic America and Br. Col., south to Kans., 

 Tex. and Ariz. Also in Europe and Asia. July-Sept. 



2. Corispermum nitidum Kit. SMALL-FRUITED BUG-SEED. Like the pre 

 ceding, but taller, 3-6 dm. high, glabrous, with ascending branches, narrower 

 leaves and lax spikes, the leaves of which are not imbricated, 3-4 mm. long and 

 generally narrower than the small -winged utricle, which is 2 mm. long. In poor 

 soil, Neb. and Kans. to Tex. and Ariz. Also in Europe and Asia. July-Sept. 

 \C. hyssopifolium var. microcarpwn Wats.] 



10. SALICORNIA L. 



Fleshy glabrous herbs, with opposite terete branches, the leaves reduced to 

 mere opposite scales, the flowers sunken 3-7 together in the axils of the upper ones, 

 forming narrow terminal spikes, perfect or the lateral ones staminate. Calyx ob- 

 pyramidal or rhomboid, fleshy, 3-4-toothed or truncate, becoming spongy in fruit 

 deciduous. Stamens 2, or sometimes solitary, exserted; filaments cylindric, short 

 anthers oblong, large; ovary ovoid; styles or stigmas 2. Utricles enclosed by th 

 spongy fruiting calyx, the pericarp membranous. Seed erect, compressed; embryo 

 conduplicate; endosperm none. [Name Greek, salt-horn; from the saline habitat, 

 and horn-like branches.] About 10 species, natives of saline soil, widely dis- 

 tributed in both the Old World and the New. Only the following are known to 

 inhabit N. Am. 



Annuals ; stem erect. 



Scales very short, acute or blunt ; spikes 2-3 mm. in diameter. i. S. herbacea. 



Scales mucronate-tipped ; spikes 4-6 mm. in diameter. 2. S. Bigelovii. 



Perennial by a woody rootstock ; stems trailing or decumbent. 3. 6". ambigua. 



X. Salicornia herbacea L. SLENDER GLASSWORT. (I. F. f. 1389.) Annual, 

 1.5-6 dm. tall; stem much branched, the branches slender, ascending or nearly up- 

 right, their joints 2-4 times as long as thick. Scales 2 mm. long or less, broadly 

 ovate or wider than long; fruiting spikes 2-8 cm. long; middle flower of the 3 at 

 each joint twice as high as the lateral ones, reaching nearly to the top of the joint; 

 utricle pubescent. In salt marshes, Anticosti to Ga. ; about salt springs in central 

 N. Y. ; in saline soil from Manitoba to Br. Col.. Kans. and Utah. Also in Europe 

 and Asia. The plant often turns bright red in autumn, forming vividly colored 

 areas in the salt marshes, hence called Marsh Samphire. July-Sept. 



2. Salicornia Bigelovii Torr. BIGELOW'S GLASSWORT. (I. F. f. 1390.) 

 Annual, stout, erect or nearly so, 5-30 cm. tall. Scales ovate or triangular-ovate, 

 sharply mucronate, 2-3 mm. long, at length spreading; fruiting spikes 1-6 cm. 

 long, their joints not longer than thick; middle flower slightly higher than the 

 lateral ones, reaching very nearly to the end of the joint; utricle pubescent. In salt 

 rrarshes, N. S. to Fla. and Tex.' Plant bright red in autumn. July-Sept. 



3. Salicornia ambigua Michx. WOODY GLASSWORT. (I. F. f. 1391.) Per- 

 ennial by a woody rootstock; stem trailing or decumbent, 1.5-6 dm. long, the 

 branches ascending or erect, slender, nearly or quite simple, rather long-jointed. 

 Scales broadly ovate or wider than high, appressed or slightly divergent; fruiting 

 spikes 1-4 cm. long, their joints not longer than thick ; flowers all about equally 

 high and about equalling the joints. On sea beaches and salt meadows, Mass, to 

 Fla. and Tex., and on the Pacific Coast. Aug.-Sept. 



ii. SARCOBATUS Nees. 



An erect much branched shrub, with spiny branches and alternate linear fleshy 

 entire sessile leaves. Flowers monoecious or dioecious, the staminate in terminal
