Morphology General Habit
Erect or ascending fleshy herb, 0.8 – 1.2 m high; roots elongate, thickened, not napiform; central stem solitary, fleshy, arising from a slightly swollen base; branching from the base upwards, moderate to abundant
Morphology Leaves
Leaves in a small rosette in young plants, alternate on the stem nearly from the base, numerous; petioles 2 – 7 mm long; laminas fleshy, oblong or elliptic, (2 –) 6 – 11 (– 18) × (1 –) 2 – 5 (– 7) cm, apex apiculate, base finely attenuate
Morphology Reproductive morphology Inflorescences
Inflorescence of compact terminal panicles, 20 – 35 (– 60) × 14 – 25 cm, branches forming lateral cymes borne on short, straight, terete peduncles 2 – 3 (– 4) cm long; cymes divided 3 – 5 times, secondary axes terete, 1.3 – 2 (– 3.5) cm long; bracts and bracteoles reduced, triangular, 1 – 1.5 mm long; pedicels filiform, slightly swollen below the flowers, 12 – 15 mm long
Morphology Reproductive morphology Flowers
Flowers open by day between 08 and 17 hours, small, ± 0.5 cm diam., numerous, > 50 per panicle; sepals 2, broadly ovate, 1 – 1.2 × 0.8 – 1 mm, subequal, caducous; petals obovate, bright yellow, base straight, apex incurved, concave, truncate; filaments 10 – 12, unequal; anthers hemispherical, bright yellow; style equalling or shorter than the filaments, filiform, scarcely swollen at the apex, stigma trifid
Morphology Reproductive morphology Fruits
Fruit a weakly 3-angled subglobose capsule opening by three separate, rapidly caducous valves; intervalvular membrane present, caducous but held up briefly by an intervalvular filament; seeds (Fig. 1C) subglobose, 1 – 1.2 × 0.9 – 1 mm, black, superficially papillose, the papillae arranged irregularly in the centre but more numerous and in concentric rings towards the edge, irregular pores between the papillae; caruncle membranous, white-hyaline, reduced or absent, caducous
Distribution
A widely distributed species, which is a common weed in tropical America from the United States through Mexico and the Caribbean region south to northern Argentina. In Bolivia it is frequent to abundant in the lowlands of Pando, Beni and Santa Cruz and in the Andean region from La Paz south to Tarija. It is found principally in dry forest in the Chaco, Chiquitania and the inter-Andean dry valleys but also occurs in more humid forest both in the Amazon basin and on the eastern slopes of the Andes. It prefers disturbed areas and often colonises cleared areas such as banks around cultivation and roadsides, where it grows amongst herbs and shrubs in full sun between 120 and 2300 m.
Conservation
A widespread neotropical weed which can be categorised as Least Concern (LC) within the IUCN (2001) guidelines.
Note
In Bolivia Talinum paniculatum can be confused with T. nocturnumBacigalupo and to a lesser extent with T. porphyreum M. Mend. & J. R. I. Wood (described below), the characters which distinguish it from these species being discussed under these two species respectively.
