GOOSEFOOT FAMILY 211 
species of Amaranths, 2 or more. The stamens are ordinarily as 
many as the parts of the calyx and opposite to them. In general 
there are 2 carpels (divisions of the pistil). The fruit is a small, 
hard, dry seed (achene) which is persistently enveloped by the 
perianth. It becomes in many instances an important indicator 
of the genus by the form which the embryo takes in the seed. If 
cut longitudinally the embryo may be seen in the form of a horse- 
shoe or in that of a complete ring or as a spiral.

Herbs with alternate leaves on lon@ leaf stems with small green 
flowers arranged in glomerate masses, without bracts, the glomerules in 
the axils of the leaves, and mostly in terminal groups. Calyx generally 
5-parted. Stamens 1 to 5. 
(The leaves used here in differentiating the species are those which are 
most typical, those from about the middle of the plant and possibly the 
general appearance of a group and not of an individual leaf.)
