--><span class="statement" id="st-undefined" data-properties=""><b>Herbs </b>perennial, caulescent, cespitose, caudex present, rhizomes or stolons present, bulbs absent. <b>Aerial</b> stems usually 2–6 from base, erect to ascending, 5–15 cm, becoming woody proximally, usually evenly strigose to strigillose from base to peduncles and pedicels, hairs straight, antrorsely appressed to closely ascending, (rarely Louisiana plants proximally villous, hair spreading), nonseptate. <b>Leaves</b> basal and cauline; stipules oblong, margins usually very narrowly flanged, apical auricles usually slightly free; petiole 2–6 cm, hairs nonseptate; leaflets 3, green to purple, cordate, (4–)6–12(–18) mm, lobed 1/5–1/3 length, abaxial surface sparsely strigose, adaxial surface glabrous or sparsely strigose, oxalate deposits absent. <b>Inflorescences</b> umbelliform cymes, very rarely irregular cymes, (2–)3–5(–8)-flowered; peduncles 4–10 cm. <b>Flowers</b> distylous; sepal apices without tubercles; petals yellow, with prominent red lines proximally, (10–)12–16(–17) mm (Arkansas, Louisiana, Texas) or 6–12 mm (Alabama). <b>Capsules</b> angular-cylindric, abruptly tapering to apex, 8–15 mm, moderately to densely puberulent to puberulent-villous. <b>Seeds</b> brown, transverse ridges white.</span><!--

|discussion=<p><i>Oxalis texana</i> is similar to <i>O. dillenii</i> in its evenly strigose to strigillose stems but differs primarily in its more numerous flowers per inflorescence and larger, distylous flowers with red-lined corolla throats. Plants of <i>O. dillenii</i> with larger flowers on elevated peduncles might be mistaken for <i>O. texana</i>, yet the two taxa exist sympatrically in the range of <i>O. texana</i> and it is clear that they are separate species.</p><!--
--><p>All Alabama plants identified as <i>Oxalis texana</i> (weighting orientation of cauline vestiture in the identifications) are from Dauphin Island and localities in and around Mobile. Compared to those in Louisiana and Texas, the Alabama plants have shorter petals [6–12 mm versus (10–)12–16(–17) mm], a more colonial habit (usually with long, lateral, stolonlike branches versus commonly with short basal offsets), and they grow in disturbed sites (versus mostly undisturbed sites, usually within woods). It is plausible that they may prove to be more closely related to <i>O. colorea</i> than to the western <i>O. texana</i>.</p>
