''Stutzia'' is a plant genus in the subfamily Chenopodioideae of the Amaranthaceae family. It was described in 2010, replacing the illegitimate name ''Endolepis''. It comprises two species, that can also be found included in the genus ''Atriplex''.〔(CalFlora Database: ''Atriplex covillei'' (Coville's orach) ) . accessed 2.22.2015〕 ''Stutzia'' species occur in western North America. == Description == The species of ''Stutzia'' are annual herbs 3-50 cm high and broad, growing erect or spreading. Young plant parts are sparsely furfuraceous or farinose, older ones glabrescent. The stems are branched nearly from base with ascending or spreading branches, the older ones with whitish bark. The numerous green leaves are alternate, petiolated or not. Their succulent leaf blades are 7–50 long and 2–30 mm wide, triangular-hastate, broadly ovate, lanceolate-ovate, lanceolate, or elliptic, with entire margins. The leaf anatomy is of the "normal" (''non-Kranz'') type of C3-plants.〔 The plants are monoecious. The inflorescences form terminal, dense or interrupted spikes of glomerulate male and often female flowers, and female flowers standing to 1-6 in the axils of midstem leaves. Male flowers (without bracteoles) consist of 5 triangular to subulate perianth lobes, ca. 1-2 mm long, united in the lower half to 3/4, smooth or with a fleshy crest, and 5 exserting stamens inserting on a disc. Female flowers are sitting within 2 opposite bracteoles, they consist of a hyaline perianth of 1–5 distinct, entire or lobed tepals, and an ovary with 2 filiform, slightly exserted stigmas.〔 In fruit, the bracteoles enclosing the fruit become accrescent, 2–20 × 1–10 mm, connate at least to the middle or to the summit. Their shape can be either ovate and entire or ovate-cordate to lanceolate, and laterally lobed at base, with acute to acuminate apices. Their surface is scurfy, usually without tubercles. The ovate, laterally compressed to subglobose fruit (utricle) greatly surpassing the perianth is not spongy, and does not fall at maturity. The membranous pericarp adheres to the seed. The vertically orientated seed with rostellate apex has a brown to dark reddish-brown, thin, crustaceous seed coat. The subannular, slender embryo surrounds the copious perisperm.〔 ''Stutzia'' is flowering from April to July.〔 The chromosome numbers are n = 9 (haploid) and 2n = 18 (diploid).〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Stutzia」の詳細全文を読む スポンサード リンク
