Characteristics

Annual, erect or ascending, 20-30 cm high, branched or not; all young parts, especially under-surface of leaves, clothed with oblong, red or white vesicles; stems and branches angular; branches obliquely erect; their vesicles, except on the angles, subpersistent. Leaves entire, in sicco thickish, retaining their indumentum of vesicles during a long time especially on the undersurface where it is very dense, hence in sicco very pale beneath, often with a reddish margin and a reddish undersurface of nerves; lower leaves on rather long, reddish vesiculose petioles, ovate from a very obtuse or rounded-subtruncate, shortly contracted base and an obtuse or rounded, very shortly pointed apex, 2-4 by 1½-3 cm; higher leaves on shorter petioles, shorter, narrower, acute, distinctly and finely acuminate. Rachises of inflorescence densely clothed with reddish vesicles. Flower-clusters subglobose, small, dense, spicate, crowded or the lower rather distant; higher spikes united in a terminal, rather small leafless paniculate inflorescence. Flowers sessile, outside densely reddish-vesiculose. Tepals 5, broadly oval, obtuse or rounded, very concave thin, 1-nerved, 1½-1½ mm long, before and after anthesis connivent. Stamens 5, about equalling the perianth; anthers thick; ovary (in our specimens) minute. Style short, 2-armed. Fruit (not seen) finely wrinkled; seed dull black or shining.
More
Herbs annual, 20-80 cm tall. Stem erect, much branched, green striate, sometimes reddish purple striate, ribbed; branches obliquely spreading, slender. Petiole 1.5-2.5 cm; leaf blade broadly to narrowly ovate, lanceolate, or oblong, 2-4 × 1-3 cm, abaxially ± gray-white farinose, adaxially light green and not farinose (or only moderately so), base broadly cuneate, rounded, or subtruncate, margin entire, pellucid, apex cuneate or shortly acuminate, mucronate. Glomerules arranged into dense or interrupted spikes or spikelike panicles on upper part of branches; rachis with fascicles of terete, multicellular hairs. Flowers bisexual. Perianth compressed globose, 5-parted; segments broadly ovate, mostly thickened abaxially and becoming star-shaped in fruit, reddish or yellowish farinose, margin membranous. Stamens 5; anthers ca. 0.5 mm. Utricle globose or ovoid, depressed. Seed horizontal, black, ca. 1 mm in diam., slightly pitted. Fl. Jun-Jul, fr. Aug-Sep.
