Staminate flowers 25–30. Pistillate flowers: ovary glabrous; styles 0.7–2.2 mm, 2-fid. Capsules depressed-globose, 9–12 × 12–16 mm, deeply 3-lobed, tardily dehiscent and appearing indehiscent, mesocarp spongy; cocci rounded, smooth, glabrous; columella 4–5.2 mm. Seeds brownish or blackish, oblong, 4.5–6 × 3–4.2 mm, rugose, irregularly reticulate; caruncle substipitate, hat-shaped, 1.6–2 × 1.2–1.5 mm.
"Annual or biennial, glabrous and glaucous, to 1 or even 2 m, usually simple to the umbel; cauline lvs opposite, linear or lance-linear, sessile at the truncate or subcordate base, those subtending the umbel similar, usually 4, those of the umbel lance-ovate to deltoid-ovate; involucres 4 mm; fr 1 cm, thick-walled, tardily dehiscent; seeds 4–6 mm, very plump, wrinkled and carunculate; 2n=20. Native of the Mediterranean region, escaped from cult. here and there in our range. May–Sept. (Tithymalus l.; Galarhoeus l.)"
An erect, glabrous, glaucous annual or biennial, thick-stemmed herb up to 1.5 m tall, but more usually 0.5-1 m tall, often with numerous axillary leafy shoots arising near the middle of the stem. Stem-leaves opposite, decussate, sessile; leaf-blades linear-lanceolate, 3-10 x 0.4-1.7 cm, acute or subacute and mucronulate, shallowly cordate at the base, entire, penninerved, dark blue-green. Pseudumbel (0-) 2-4-rayed, sometimes many times bifid; axillary rays 0 or few below the pseudumbel; pseudumbel-leaves 2-4, opposite or whorled, ovate-lanceolate or oblong-lanceolate, slightly smaller than the upper stem-leaves; ray-leaves opposite, triangular-ovate, acutely acuminate, pale green, shorter and broader than the pseudumbel-leaves. Cyathia pedunculate, pale green, the peduncle purplish. Glands 2-homed, the horns divergent, spathulate, yellowish-green blotched with purple. Fruit hexalobate-subglobose, 0.9-1.3 x 1.3-1.7 cm, smooth when fresh, wrinkled with age, with a spongy mesocarp and woody endocarp. Styles erect or recurved, 2.5-3 mm long, ± free, deeply bipartite, the stigmas slightly thickened. Seeds ovoid, somewhat laterally compressed, truncate at both ends, obliquely so at the apex, 4.5-5 x 3-3.5 x 3.5-4 mm, vermiculate-rugulose, pale grey or brownish, with a small patelliform caruncle.
