Author: Scott A. Mori

Type: French Guiana. Without locality, Jul 1824(fl), Poiteau s.n. (lectotype, K, photo K neg. 16376 at NY, designated Fl. Neotrop. Monogr. II. 1990)

Description: Trees, to 35 m tall, usually unbuttressed. Twigs gray, nearly smooth to slightly rimose, 2-5 mm diam., with vertically oriented lenticels. Bark brown or grayish brown, with poorly developed, vertical fissures, the slash pink or salmon colored. Sapwood yellowish white, the heartwood maroon. Leaves not decidcuous just before anthesis; petioles 10-25 mm long, glabrous or puberulous; blades oblong, elliptic, or infrequently oblanceolate, 8-25 x 4-10 cm, glabrous except for infrequently puberulous midrib on abaxial surface, chartaceous to coriaceous, the base acute to obtuse, the margins entire, slightly revolute, with scars left by caducous hairs, the apex acute to obtuse; secondary veins in 11-23 pairs. Inflorescences simple racemes or once-branched paniculate arrangements of racemes, terminal or axillary, the principal rachis 4-15(-25) cm long, puberulous; pedicels jointed, 1-3 mm long below joint, 1-5 mm long above joint, rugose, green. Flowers 2.5-3 cm diam.; calyx with 6 ovate to widely ovate lobes, 2-8 x 2-5 mm; petals 6, widely obovate, 11-19 x 8-14 mm, pink, red, violet, or purple, often with tinges of white on margins; androecium: staminal ring with 150-190 stamens, the filaments white, not dilated at apex, 1-2 mm long, the anthers ca.0.5 mm long, those on appendage free ligule side of ring white, otherwise yellow; appendage free ligule white; hood flat, dorsiventrally expanded, 10-14 x 6-12 mm, pink or reddish, the appendages nearly entirely fused, antherless; hypanthium rugose, puberulous, obtuse or truncate at base; ovary 4-locular, each locule with 4-8 ovules attached on lower part of septum, the summit truncate or convex, the style geniculate or slanted toward anterior end of flower, 3-5 mm long. Fruits broadly conical, turbinate, or globose, 2.5-5 (excluding operculum) x 2.5-4.5(6) cm, the pericarp 1.5-4 mm thick, with horizontally oriented rugae, these often less visible or absent with age, the style persistent on operculum as dull spine. Seeds several per fruit, brown, 22-25 x 15-18 mm; aril unknown.

Common names: See descriptions of each of the subspecies.

Distribution: The two subspecies of L. corrugata are collectively found from western Venezuela, throughout the Guianas, into eastern Amazonian Brazil.

Ecology: See descriptions of the subspecies.

Phenology: See descriptions of the subspecies.

Pollination: See descriptions of the subspecies.

Dispersal: See descriptions of the subspecies.

Predation: No observations recorded.

Field characters: See descriptions of the subspecies.

Taxonomic notes: This species consists of two subspecies. Subspecies corrugata has leaves that show a reticulate network of higher order veins, are dull, and do not show striations adxailly (see attached images below of the leaves of both subspecies). This subspecies is found mostly in the Guianas and eastern Amazonian Brazil. In constrast, subsp. rosea has shiny smooth, leaves without an obvious reticulate network of veins adaxially. It is found mostly in Venezuela, including N of the Andes in the Maracaibo Basin, and in north central Amazonian Brazil.

Conservation: IUCN Red List: Not onl list.

Uses: See descriptions of each of the subspecies.

Etymology: The epithet refers to the horizontally wrinkled hypanthium and young fruits. This feature becomes less evident as the fruits mature.
