Multi-stemmed and much-branched, erect or occasionally prostrate to ascending annual herb, c. 0.3–1 m. tall, Stem and branches striate, somewhat swollen at the nodes; indumentum very variable, from nearly hairless or with sparse soft pubescence to densely pilose. Leaves cordate-ovate to broadly ovate, obtuse to acuminate at the apex, 1.3-7 cm long, the lowest on petioles up to c. 1 (1.8) cm. long, leaves towards the ends of the stem and branches reducing in size and almost sessile; indumentum very variable, from green on both surfaces and moderately softly appressed-hairy beneath to moderately appressed-pilose above and densely silvery hairy beneath. Inflorescence a large, open compound panicle; peduncle and branches of the partial inflorescences capillary, hairless or with long, strigose, hairs; bracts lanceolate, 0.75–1 mm. long, sparingly pilose, mucronate with the excurrent midrib; bracteoles similar but slightly shorter. Flowers sessile. Tepals, green, acute, prominently 3-nerved, hairless or usually more or less furnished with spreading, white hairs; outer 2 tepals 2–2.5 mm. long; inner 2 widely hyaline, pilose only along the midrib. Style short, c. 0.5 mm. long. Stamens delicate, c. 1.5–1.75 mm. long; pseudostaminodes absent. Capsule ovoid, c. 1.75–2 mm. long. Seed subglobose, black, shining, feebly reticulate, c. 1.5 mm. in diameter. |
