Plant Characteristics:
Annual herb, stems slender, much branched, ascending or decumbent, subglabrous
or pubescent above; nodes without spines; lf. blades rhombic-ovate to
lanceolate, obtuse, 5-20 mm. long, on slender petioles ca. as long; fls.
polygamous, in dense short and thick spikes, which are usually subtended by a
few capitate axillary clusters; bracts ovate, acute, cuspidate, usually much
shorter than the calyx, ca. 2 mm. long; sepals 2-3, oblong, ca. as long as
bracts; utricle oblong, indehiscent, much exceeding calyx, 3-5-nerved, with
fleshy walls; seeds dark red-brown, oval, 1 mm. long.
Habitat:
Weed in gardens, along streets, etc. at widely scattered stations,
cismontane s. Calif. May-Nov.
Name:
Greek, amarantos, unfading,
because of the dry persistent calyx and bracts.
(Munz, Flora So. Calif. 60). Deflexus,
bent abruptly downward. (Bailey
13).
General:
Rare in the study area having been found only once and this on the bank
above the fresh water stream at 23rd St. (my
comment). Unlike
the other species of Amaranthus
described, the fruit does not split open at maturity.
(Robbins et al. 163).
Indians of Arizona so valued the seeds of amaranth that they cultivated
the plant. They parched and ate the
seeds whole or ground them into flour. They
also used the leaves and stems of the young plants as a potherb.
They brought the seed heads home to dry-often under a shelter of willow
made just for that purpose. The
spikes were beaten with sticks on a hard floor and then winnowed.
(Clarke 179).
About 50 species, widespread except in cold regions.
(Munz, Flora So. Calif. 60).
Uncommon waif. Plants with
wrinkled seeds have been called A.
gracilis. (Hickman, Ed. 132).
