“ENDOLEPIS, N. Gen. 
“Flowers monoecious ; the male ebracteate, in glomerate terminal spikes ; the female solitary 
and sessile in the axils of the leaves. Masc. Calyx gamosepalous, urceolate, five-lobed ; the lobes 
thin, triangular—subulate strongly indexed, each with a fleshy, protuberant gibbosity at its base 
outside. Stamens five ; filaments subulate, short; anthers oblong, large scarcely exserted. No 
rudiment of an ovary. Fern . bibracteate ; the bracts ovate, membranaceous, inappendiculate, 
united to the summit, forming a compressed theca which encloses the flower. Calyx of three 
distinct sepals. No stamens nor staminodia. Ovary ovate ; styles two, distinct, filiform, slightly 
exserted ; ovate erect. Utricle ovate, compressed, enclosed in the membranaceous theca. Seed 
ovate, rostellate at the summit, vertical, embryo nearly annular, very slender ; radicle superior. 
An annual low herb, in aspect resembling Chenopodium or Atriplex, with lanceolate acute, 
entire leaves. 
“Endelopis Suckleyi, n. sp. (Plate III.) As a genus this is characterized among Atriplices 
both by the remarkable calyx of the staminate flowers, and by the presence of a manifest 
three-sepalous calyx in the fertile flowers. The species is dedicated to my former pupil, the 
discoverer. ’ ’ —Torrey. 
Obione canescens, Moquin. 
Obione argentea, Moquin ? 
Obione Suckleyana, Torr., n. sp. (Plate IY.) “Annual, stem branching, prostrate; leaves 
suborbicular on long petioles, acutely repand-dentate, pale-green both sides, nearly glabrous ; 
glomerules axillary, monoecious bracts of the sessile fruit deltoid, united to the summit, the 
margin narrowly winged, crenate-denticulate. Yery distinct from every other North American 
species of Obione, but having some resemblance to 0. argentea. It is remarkable for the 
roundish leaves, very long petioles, and the large and much compressed nearly glabrous fruit. 
The male flowers were tetramerous.”— Torrey; This was collected in the Milk River valley, 
August 19.
