Subshrub with several stems 10–50 cm. tall from a mostly creeping woody rhizome; stems usually only leafy at the upper nodes, glabrous to densely pubescent, often becoming covered with soft corky bark. Leaf blades 3–22 x 0.6–5.4 cm., narrowly elliptic to elliptic but variable and sometimes obovate, elliptic-ovate or linear-oblong, rounded to acute at the apex, narrowly cuneate at the base, glabrous to pubescent above and beneath, mostly distinctly paler beneath and sometimes whitish; domatia absent; nodules mostly numerous, scattered in the lamina and often not easy to see; petiole 0.3–2 cm. long, glabrous or pubescent; stipules 3–8 mm. long, ovate-triangular, entire at the apex or bifid for almost 1 mm., either thin and soon deciduous or thick and woody and ± persistent. Flowers heterostylous, 5-merous, in usually ± dense slightly branched inflorescences 1.5–5 cm. long; peduncle 0.5–3 cm. long, pubescent or glabrescent often bent ± at right angles; secondary branches 0.3–1.3 cm. long, similarly hairy; pedicels 1–2 mm. long, attaining 5 mm. in fruit, glabrous or pubescent; bracts small, filiform, ± 3 mm. long. Calyx tube ± 1 mm. long, subglobose, glabrous or pubescent; limb 0.75–1.5 mm. tall, cupuliform, usually glabrous, more rarely densely hairy; lobes unequal, 1–2 mm. long, mostly triangular-lanceolate, usually ± ciliate on the margins, or rarely lobes obsolete.Corolla white or cream, glabrous outside; tube 3–5 mm. long; lobes 2.5–3.5 x 0.8 mm., narrowly oblong. Drupes red, 3.5–6 x 7–10 mm., didymously biglobose, glabrous or pubescent, sometimes with only 1 pyrene due to abortion; pyrenes 5 x 4 x 4 mm. subglobose. Seeds subglobose, ventral surface with a deep Y- or V-shaped fissure and, save for the area of the junction of the 2 pyrenes, having a spherical air space between the hard outer layers and the albumen, which is not otherwise ruminate. |
