CLXXXI. CHENOPODE^. mS 



agglomerated, axillary or terminal, bracteate and 2-bracteolate or naked. Calyx of 

 5, 3, 2 sepals (rarely 4), more or less coherent at tlieir base, herbaceous, greenish, 

 imbricate in gestivation, sometimes becoming fleshy and bacciform after flowering, 

 or dry and capsular. Corolla 0. Stamens usually hypogynous, or at the bottom 

 of the calyx, 5, or rarely fewer by arrest, all fertile and opposite to the sepals ; fila- 

 ments flliform or subulate, usually free, sometimes shortly united into a cup ; stami' 

 nodes (in some genera) very small, placed between the filaments {Anabasis, &c.) ; 

 anthers 2-celled, ovoid or oblong, introrse, dehiscence longitudinal, connective some- 

 times vesicular above the cells (Physogeton). Ovaet ovoid, or depressed-globose, 

 usually free, very rarely adherent by the base, 1-celled ; stigmas 2-4, distinct, or 

 coherent at the base ; ovule campylotropous, sessile at the bottom of the cell, or 

 fixed laterally, or pendulous to a short funicle, micropyle facing the base, circum- 

 ference or top of the ovary. Feuit a utricle or caryopsis, or rarely a berry, included 

 in the variously modified or unchanged calyx. Seed horizontal or vertical, erect or 

 inverted, lenticular or reniform, integument double, of a crustaceous testa and mem- 

 branous endopleura, or simple and membranous ; albumen copious or scanty or 

 {Anabasis, Salsola, &c.), usually farinaceous, very rarely sub-fleshy. Embkto curved 

 or annular, and surrounding the albumen, or coiled into a flat spiral, and dividing 

 the albumen into 2 parts, or exalbuminous, and forming a conical spiral {Salsola) ; 

 radicle facing the hilum ; cotyledons plano-convex, slender.
