412 AMARANTACE.E. (AMARANTH FAMILY.) 



small, green, tinged with red, or sometimes crimson as in A, caudatus, L., the 

 Prince's Feather of the gardens. (A. sanguineus, L.) — In gardens, &c. 

 (Adv. from Trop. Amer.) 

 -t- -i- Green Amaranths, Pigweed. Flowers green, rarely a little reddish. 



3. A. retroflexus, L. Roughish and pubescent, or smoothish; leaves 

 dull green, long-petioled, ovate or rhombic-ovate, undulate ; spikes crowded in a 

 stiff or glomerate panicle ; bracts awn-pointed, rigid, exceeding the calyx. — Var. 

 ciilorostachys (A. clilorostachys, Willd.) is smoother, with brighter green 

 leaves and less thick and crowded spikes, apparently passing into var. hybridus 

 (A. hybridus, L.), which is smooth and more loosely panicled, — perhaps not in 

 our district. — Cultivated and manured soil, gardens, &c. Probably indigenous 

 southwestward. (Adv. from Trop. Amer.?) 



* * Flowers crowded in close and small axillary clusters: stems low, spreading or 

 ascending : stamens and sepals 3, or the former only 2. 



4. A. Albus, L. Smooth, pale green ; stems whitish, mostly spreading next 

 the ground ; leaves long-petioled, obovate and spatulate-oblong, very obtuse or 

 retuse ; flowers greenish ; sepals mucronate, half the length of the rugose fruit, 

 much shorter than the rigid pungently pointed bracts. — Waste grounds, near 

 towns, and roadsides : common. (Nat. from Trop. Amer. ?) 



§ 2. Utricle thinnish, bursting or imperfectly circumcissile : flowers monacious. 



5. A. spin6sus, L. (Thorny Amaranth.) Smooth, bushy-branched; 

 stem reddish; leaves rhombic-ovate or ovate-lanceolate, dull green, a pair of 

 spines in their axils ; upper clusters sterile, forming long and slender spikes ; 

 the fertile globular and mostly in the axils ; flowers yellowish-green, small. — 

 Waste grounds, Pennsylvania, Ohio, and southward. (Nat. from Trop. Amer.) 



§ 3. EtlXOLUS, Raf. Utricle rather fleshy, remaining closed or bursting irregu- 

 larly: no spines: bracts inconspicuous. 



6. A. lividus, L. Smooth, somewhat succulent, much branched (l°-3° 

 high) ; leaves livid-purplish, long-petioled, ovate or oval ; flower-clusters greenish, 

 sessile in the axils and crowded in a terminal interrupted spike ; stamens 3 ; se- 

 pals mostly 3, rather shorter than the ovate smoothish fruit. (Eiixolus lividus, 

 Iiif.) — Coast of Virginia, Clayton. Probably an introduced species, and to in- 

 clude A. oleraceus, L., and the next. 



7. A. pumilus, Raf. Low or prostrate ; leaves more fleshy and obovate, 

 emarginate, the ribs stouter and transverse ; flower-clusters small and axillary ; 

 stamens and sepals 5, the latter half the length of the obscurely 5-ribbed fruit : 

 probably a maritime form of the preceding. (Euxolus pumilus, Raf) — Sandy 

 beaches, Rhode Island to Virginia and southward. 



8. A. vfuiDis, L. Smooth or minutely pubescent, spreading or ascending 

 (6'- 18' high); leaves pale green, ovate or ovate-oblong, long-petioled; flowers 

 much smaller than in the preceding, in axillary clusters and usually also in a 

 terminal spike; sepals and stamens 3, the latter thin, shorter than the small 

 globose-ovate roughish fruit. (Euxolus deflexus, Ed. 2; but that lias a larger 

 and more elongated smooth 3-nerved utricle.) — Streets of Albany, New York : 

 depauperate form with the terminal spike undeveloped. (Adv. from Eu.)
