 ing reddish brown, the branches ascending, very leafy. 

 Leaves linear or linear-lanceolate, short-petioled or 

 the upper- sessile, obtuse at the apex, narrowed at the

 the midvein prominent, the lateral veins few; flowers 

 monoecious, densely capitate in the upper axils, form- 

 ing terminal leafy spikes; bracts lancolate, 2"-4" 

 long in fruit, appendaged by 4 tufts of spreading hairs; 

 calyx-lobes acute, pubescent; utricle loose, the pericarp 

 readily separating from the large seed.

9. AXYRIS L. Sp. PI. 979. 1753- 

 Annual herbs with alternate entire petioled leaves and small monoecious flowers, the

 3-5-parted ; stamens 2-5. Pistillate calyx 3-4-parted ; ovary suborbicular, somewhat flattened; 

 stigmas 2, filiform, connate at the base. Utricle obovate to cuneate, winged or crested at 

 the apex, enclosed in the perianth. Seed erect ; embryo horseshoe-shaped ; endosperm 

 copious. [Greek, mild to the taste.] 



Five or six species, natives of northern Asia, 

 the following typical.

Erect, often much branched, l°-2° high, pubes- 

 cent, the slender branches ascending. Leaves 

 ovate, elliptic or lanceolate, entire, acute or 

 obtusish, narrowed at the base, thin, li'-3' long, 

 the slender petioles 3"-/" long; staminate flow-

 PI- 4- 1753- 



Annual herbs, with alternate narrow entire i-nerved leaves, and perfect bractless small 

 green flowers, solitary in the upper axils, forming terminal narrow leafy spikes, the upper 

 leaves shorter and broader than the lower. Calyx of a solitary thin broad sepal, or rarely 2. 

 Stamens 1-3, rarely more, and one of them longer. Ovary ovoid, styles 2. Utricle ellipsoid, 

 mostly plano-convex, the pericarp firmly adherent to the vertical seed, its margins acute or 

 winged. Embryo annular in the somewhat fleshy endosperm, its radicle pointing downward. 

 [Greek, bug-seed.] 



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