Morphology General Habit
Annual herb, erect or with decumbent lower branches, 7–60 cm.
Morphology Stem
Stem generally rather stout, simple or branched below the middle, yellowish, sulcate-angular, glabrous below and with rather long ± flexuous multicellular hairs especially in the flowering region, or glabrous throughout.
Morphology Leaves
Leaves glabrous or with scattered short hairs on the lower surface of the veins near the base, long-petiolate (petioles 0.5–5 cm. long, sometimes exceeding the lamina); lamina broadly ovate to elliptic-oblong, 1.2–4 × 0.6–3 cm., cuneate to shortly attenuate at the base, obtuse to broadly retuse at the apex.
Morphology Reproductive morphology Flowers
Flowers in compact spherical sessile axillary clusters to ± 1 cm. in diameter, scattered thickly along the stem and branches; ♂ and ♀ flowers intermixed.
Morphology Reproductive morphology Inflorescences Bracts
Bracts and bracteoles similar, small, oblong with a green midrib which is at most minutely percurrent; bracteoles shorter than the perianth.
Morphology Reproductive morphology Flowers Perianth
Perianth-segments 3, 1–1.25 mm.; ♂ elliptic-oblong and usually apiculate, ♀ oblong and obtuse; both with a central green vitta ceasing below the apex.
Morphology Reproductive morphology Flowers Gynoecium Stigma
Stigmas 2, short and rigid.
Morphology Reproductive morphology Fruits
Fruiting heads ± 8 mm. in diameter, rigidly stellate with the divergent capsules. Capsule 2.75–3.25 mm., rather woody, dehiscent, the persistent base conical and longitudinally sulcate, the lid subconical, also sulcate below but smooth at and below the style-base, point of junction of lid and base ± cristate-crenulate.
Morphology Reproductive morphology Seeds
Seeds ellipsoid, 1.25–1.5 mm., slightly compressed, black, shining, very feebly reticulate.
