AMARANTACEZ. 
G THUS* RIGIDIFLORUS, Hook.—Stem prostrate, diffusely 
branched ; cauline leaves secund, 2-4” long, 1-2’ wide, acute, tapering 
to a rather broad base; flowers in axillary clusters; sepals membranous; 
filaments a little longer than the oblong anthers; stigma 2-lobed—Camp 
Bowie, Arizona, on limestone soil (507). Whole head of flowers densely 
covered with long cottony hairs, which, under a low-powered objective, are 
found to be transparent, jointed, and slightly swollen at the proximal side 
of the joint on account of the granular matter which accumulates there. 
ALTERNANTHERA LANUGINOSA, Torr—Arizona (557). Apparently an 
excessively variable plant, so far as my imperfect specimens enable me to 
decide. 
NITROPHILA OCCIDENTALIS, Watson (Banalia, Moq.).—Nevada. 
GOMPHRENA NiITIDA—Erect, 6-14’ high, branching from the axils; 
branches sometimes nearly as long as the main stem; stem and branches 
somewhat silky-hairy; leaves oblong-spatulate, 1-3’ long, 4-8” wide, 
obtuse, mucronulate, cinereous, somewhat silky (younger ones densely so, 
and under an inch objective the hairs are seen to be beautifully jointed) ; 
heads sessile or nearly so, pearly-white (no trace. of red), subtended by 
two (or more) large leaves; bracts membranous, usually somewhat lacerate- 
toothed or crested on the back, broadly lanceolate, tapering into a very 
acute point; sepals very acute, membranous, abundantly hairy below and 
outside, somewhat shorter than the bracts; stamineal tube united to the top, 
middle lobe of the filament nearly obsolete, anthers oblong; style three- 
fourths as long as the tube——Chiricahua Mountains, in Southern Arizona, 
on rocky knolls (520). The hair on the back of the sepals is (under a 
moderate power) seen to be quite long comparatively, and with the peculiar 
* GOSSYPIANTHUS, Hook.—F lowers hermaphrodite {2-3-bracted]. Calyx of 5 erect, subequal. 
very villose sepals. Stamens 5, free. Filaments subulate. Anthers unilocular, ovate. Bingle-celied 
ovary with oneovule. Style very short, roundish. Stigma emarginate, 2-3-lobed. Single-seeded utricle 
ovate, valveless, included in the calyx. Seed vertical, ovate-lenticular, sub-reniform ; testa crustaceous, 
Embryo coiled around the central, farinaceous albumen ; radicle ascending.—North American perennial 
herbs, with procumbent, flexuose, woolly stems. Radical leaves petioled or sub-sessile, obovate or elon- 
gated-spathulate, rigid, sub-coriaceous ; cauline opposite, sessile, much smaller, ovate, entire, more or less 
silky-woolly. Flowers axillary, densely aggregated, covered with copious flexuose wool, the deciduous, 
delicate bracts keeled and concave.—Mogquin, DC. Prod. 13, pars 2, p. 337.
