Description:
Author: Scott A. Mori & Nathan P. Smith
Type: Colombia. Antioquia: Woods of Carmen, Jul 1845 (fl), Purdie sn (lectotype, K, here designated; isolectotype, BM).
Description: Trees, small, slender; leaf-bearing branches 5-7 mm in diam., with the leaves densely congested at their ends. Leaves: petioles slender 20-50 x 2 mm, subterete in cross section; blades very narrowly elliptic to narrowly oblanceolate, 25-46 x 2-3.5 cm, glabrous, chartaceous, the base long and narrowly cuneate, the margins distinctly serrulate, the apex acuminate or attenuate; secondary veins in 22-29 pairs. Inflorescences axillary or cauline, pubescent, the rachis short; pedicels 15-50 mm, subtended by a single oblong basal bract 5 x 2 mm and bearing near the middle 2 oblong to lanceolate bracteoles 5-6 x 2-3 mm. Flowers 10 cm in diam.; hypanthium without costae, pubescent; calyx-lobes 4, rounded to broadly obtuse, 2.5-8 mm; petals 8, narrowly obovate or oblanceolate, 45 x 23 mm, puberulous at anthesis, pink or purple; androecium actinomorphic, connate at base, the tube 15 mm in diam., 12 mm high, yellow, the outermost filaments 18 mm, pink to dark purple, the anthers 2.5 mm, yellow; gynoecium with 4-locular ovary, the summit densely white-woolly, the style 1.5 mm, the stigma 4 lobed. Fruits poorly known, globose, truncate at apex. Seeds poorly known, elliptical to rounded and angular, ca. 1.5-2 cm diam.; aril present, basal.
Common names: None known.
Distribution: This species is native to states of Antioquia and Cesar but has been cultivated at the Rio de Janeiro Botanical Garden and the Singapore Botanical Garden.
Ecology: -
Phenology: Flowers have been colleced in Mar, Apr, and Nov. Fruits have been collected in Feb and May.
Pollination: No reports of pollination have been recorded.
Dispersal: No reports of dispersal have been recorded.
Predation: No observations recorded.
Field characters: This species is characterized by its very narrow leaf blades; pinkish to purple flower petals, hypanthium without costae; and seeds with a basal aril.
Taxonomic notes: The very narrow leaves of this species are unique in Gustavia.
Conservation: IUCN Red List: Endangered B1+2c ver 2.3 (Calderon, E. 1998. Gustavia gracillima. In: IUCN 2013. IUCN Red List of Threatened Species. Version 2013.2. www.iucnredlist.org. Downloaded on 05 March 2014.).
Uses: Cultivated as an ornamental.
Etymology: The name “gracillima” means most graceful or slender and probably refers to habit of this species.
