The calyx is three- to five-lobed or parted, rarely of one sepal (Monolepis), or is entirely wsint- ing in the pistillate flowers of some genera {Atriplex). The calyx is persistent in the fruit. There are usually as many stamens as lobes of the perianth, rarely fewer ^iesia {Chenopodium spp.); the filaments are com- monly slender and bear longitudinally dehis- cent, two-celled anthers. The ovary is superior, free from the calyx and one-celled; ^£23o the styles are terminal, short or elongated, ff^PyS^P^'''^ one to three in number, and bear capitate stigmas. It has a single, erect ovule. —The msiture fruit is a utricle (one- Fig. ht.—a. seeded fruit with a loose pericarp) with mem- sarcobatus^^° b, branous, leathery, or thin pericarp. The annular embryo seeds may possess an abundance of endo- sperm {Beta, Eurotia, etc.), or none (Sarcobatus, Salsola); the embryo is spirally coiled (Fig. 117) (Salsola), annular (Beta), or conduplicate {Salicornia). Key to Principal Genera Embryo spirally coiled (Fig. 117); endosperm little or none. Shrubs, Sarcobatus (greasewood). Herbs, Salsola (Russian thistle). Embryo not spirally coiled, partly or completely annular (Fig. 117); endosperm abundant. Flowers perfect (polygamous in Kochia). : with five lobes, about the base of which is developed a wing, Ko( hia. Calyx wingless, persistent. Lobes of calyx becoming fleshy and bright red, Blitum (strawberry blite)..
