description: KEY TO THE SPECIES OF <i>DRYMONIA</i> IN MEXICO All species in this key reflect an ongoing monograph of <i>Drymonia</i> and are documented by recently annotated specimens from the Universidad Nacional AutÓnoma de México (MEXU) and other herbaria. The presence of <i>D. macrophylla</i> in Mexico is based on a single collection from Chiapas. Several specimens are present in Guatemala along the border with Mexico and it is likely that documented populations of <i>D. macrophylla</i> along the Guatemalan border extend into Mexico. 1. Plants subwoody;blades exceeding 20 cm long and 10 cm wide;inflorescence of several (&gt; 3) flowers congested in the upper leaf axils, peduncle 5–9 mm long, bracts&gt; 2.5 cm long; calyx lobes with obtuse apex; fruits with a red cone of seeds_________________________________________________________________ <b>Drymonia macrantha</b> (Donn.Sm.) D.N.Gibson 1. Plants mostly herbaceous,rarely subwoody;blades rarely exceeding20 cm long and10 cm wide,if so,calyx lobes serrate, dentate or fimbriate; inflorescence reduced to 1–3 flowers per axil, peduncle absent, bracts absent or &lt;2.5 cm long; calyx lobes with acute to attenuate apex,sometimes mucronate;fruits with yellow to black,never red, cone of seeds. 2. Leaves entire,rarely exceeding 3 cm wide,glabrous above,(3–)4 pairs of primary lateral veins;calyx uniformly cream to pale green;corolla throat and limb purple _____________________________________ <b>Drymonia mexicana</b> Clavijo &amp; J.L.Clark 2. Leaves subentire, crenate,denticulate, serrulate or serrate, usually exceeding 3 cm wide, puberulous to strigose or scabrous above,4–9 pairs of primary lateral veins;calyx green to green suffused with reddish,orange,or completely pink or dark red;corolla throat and limb white to bright yellow or pink,often with orange,dark red,purple or maroon areas. 3. Leaves light green below,base attenuate or decurrent;pedicel with apex engrossed,5-winged,up to 34 mm long; calyx pink to blood red,lobes equal;corolla uniformly bright yellow,throat laterally compressed _________ <b>Drymonia strigosa</b> (Oerst.) Wiehler 3. Leaves light green to purplish-red below,base rounded to cuneate,sometimes oblique; pedicel terete, rarely ex- ceeding 25 mm long;calyx green suffused with red or maroon,sometimes all maroon,lobes subequal;corolla white to pink,often with orange,dark red, purple or maroon areas in throat and limb,throat ampliated. 4. Younger parts of the branches and petioles pilose; blades subentire, 4–5 pairs of primary lateral veins; calyx lobes with attenuate apex; corolla 30–40 mm long, white to yellow, limb sometimes suffused with pink ____________________________________________________________ <b>Drymonia oinochrophylla</b> (Donn.Sm.) D.N.Gibson 4. Younger parts of the branches and petioles puberulous to strigose; blades crenate to serrate or dentate, 6–9 pairs of primary lateral veins; calyx lobes with acute or acuminate apex, sometimes mucronate; corolla 30–70 mm long,white to pink,limb often with orange,dark red,purple or maroon veins or spots. 5. Leaves ovate, oblong, or oblanceolate, sometimes falcate; calyx ovate, serrate, dentate or fimbriate, apex acuminate, sometimes mucronate, 10–15(–28) × 6.6–7.5 mm; corolla pale yellow or cream, usually more yellow inside and with a red or orange areas on the lower surface in the throat, tube with a short spur; style puberulent,stigma stomatomorphic ______________________________ <b>Drymonia macrophylla</b> (Donn.Sm.)
