    Description - Trees, to 15 m tall, without buttresses. Bark light gray, smooth to slightly warty. Leaf blades narrowly oblong, 26.5-37 x 7.5-12.5 cm., glabrous, chartaceous, punctate abaxially, with 20-28 pairs of lateral veins, these impressed above, salient below, joining superadjacent veins to form marginal vein; apex acuminate to very long acuminate; base obtuse; margins entire, slightly revolute; petiole 10-18 mm long. Inflorescences cauline, from warty outgrowths on trunk, unbranched or infrequently once-branched racemes, the rachis 6-8 cm long, warty, the pedicels 10 mm long, glabrous, without conspicuous lenticels. Flowers 5-7 cm diam.; calyx with six lobes, the lobes very widely ovate, 3.5-4 x 4-5 mm, spreading, not imbricate, convex abaxially, flat adaxially; petals six, widely obovate, 25-30 x 15-18 mm, reddish-violet; hood of androecium with triple coil, reddish-violet; staminal ring with ca. 200 stamens, the filaments clavate, 1.5 mm long, the anthers 0.5 mm long; hypanthium truncate at base, glabrous, without conspicuous lenticels; ovary 2-locular, each locule with five ovules attached to placenta on floor of locule, the style curved, 3.5 mm long. Fruits depressed globose, 10 x 20 cm, the pericarp leathery; operculum convex, umbonate. Seeds wedge-shaped in cross section, 5.5-6 x 3-5 cm, with fleshy, yellow-white aril on inner edge.

  • Discussion

    Eschweilera rimbachii is morphologically similar to E. caudiculata from which it differs by its longer leaves, more pronounced marginal vein, and larger seeds.

  • Distribution

    Eschweilera rimbachii is known only from a few collections gathered between 500 and 2000 m in W Ecuador and SW Colombia. It flowers from Mar to Nov.
