Description:
Description - Trees, to 20 m tall. Twigs thick, 6-9 mm diam. below uppermost leaf, rust-colored, rimose, with horizontally oriented scales. Leaf blades narrowly obovate, 35-40 x 15-19 cm, glabrous, with papillate abaxial surface, chartaceous, with 3034 pairs of lateral veins; apex abruptly acuminate; base obtuse; margins entire to minutely crenulate; petiole 12-20 mm long, glabrous, canaliculate. Inflorescences racemose, terminal, the rachis 10-30 cm long, with 3-4 widely spaced flowers, the lower 3/t without flowers, with horizontally elongated lenticels; pedicels jointed, sessile below joint, 5 mm long above joint, with caducous, cucullate bract, 35-50 x 20-25 mm and two caducous, cucullate bracteoles, 15-17 x 10-12 mm, the margins fimbriate. Flowers large, ca. 11 cm diam.; calyx with six very widely oblong to widely ovate pink lobes, 12-14 x 9-11 mm, the margins erose; petals six, widely obovate, white adaxially, pink to red abaxially, 45 x 30 mm; hood of androecium flat, white, the proximal appendages with anthers, the distal appendages antherless; staminal ring with ca. 1000 densely packed stamens, the filaments ca. 3 mm long, not markedly dilated at apex, white, the anthers 1 mm long, yellow; hypanthium glabrous; ovary 4(-5)-locular, each locule with 4-9 ovules attached at base of septum, the summit truncate, the style 7 mm long. Fruits depressed globose, 4.5-7 (without operculum) x 9-11 cm, the base truncate, the pedicle attachment prolonged into woody knob 1 x 2 cm, the calycine ring with persistent, thickened, downwardly oriented sepals, situated near base of fruit, the supracalycine zone erect, the pericarp 10-15 mm thick; operculum slightly convex, umbonate, the umbo ca. 15 mm long. Seeds with small, white, basal aril.

Discussion:
Lecythis barnebyi is morphologically similar to L. poiteaui from which it differs by having larger leaves with more pairs of lateral veins and by having adaxially pink to red instead of white or greenish-white petals. In addition, the leaves of L. barnebyi are widest above the middle instead of at the middle as in L. poiteaui. Both species possess papillate abaxial leaf surfaces and their floral structure is similar.
