Description:
Author: Scott A. Mori
Type: Panama. Panama, primary forest along newly cut road from El Llano to Carti-Tupile, continental divide to 1 mile from divide, 30 Mar 1973 (fl), R. L. Liesner 1312 (holotype, MO 233058; isotypes, MO, NY).
Description: Trees, usually unbranched, to 5 m tall, the leaves in 1-5 clusters at branch ends, the terminal cluster with 16-28 tightly congested leaves. Leaves: petioles usually missing or infrequently to 80 mm; blades oblanceolate to spathulate, 82-120 x 18-33 cm, glabrous, the base acute to rounded, the apex acuminate, the margins serrulate to serrate toward apex; secondary veins in 34-45 pairs . Inflorescences suprafoliar, the flowers solitary in bract axils, 6-8 flowers clustered near branch apex within rosette formed by terminal cluster of leaves, appearing terminal but continued vegetative growth is monopodial; pedicels 30-40 mm long, subtended by a single oblong to spathulate bract to 115 x 33 mm (these bracts diminishing distally) and bearing slightly below hypanthium 2 oblong to ovate, cucullate bracteoles 15-20 x 14-19 mm. Flowers ca 13 cm diam.; calyx-lobes 4, very widely ovate, 16-25 x 23-40 mm, imbricate, somewhat auriculate at base; petals 8, narrowly obovate, 55-60 x 27-35 mm; androecium base ca. 9 mm high, the outermost filaments 22-25 mm long, pubescent, the anthers 2.5-3.5 mm long; ovary puberulous, 5-8-locular, each locule with 50-93 ovules, the summit white-tomentose, the style 2 mm long. Fruits globose, 50 x 70 mm, brown with white speckles, with 4 persistent calyx lobes, the mesocarp yellow-orange at fruit maturity. Seeds 2-5 per locule, to 22 x 18 mm; funicle not known.
Common names: None recorded
Distribution: Know only from eastern Panama (Provinces of Darién, Panama, and San Blas) into northwestern Colombia (Chocó).
Ecology: An understory tree of lowland, wet forests usually below 500 elevation
Phenology: Flowering collections have been gathered in January and March in Panama and in February in the Colombian Chocó
Pollination: No observations recorded but probably pollinated by buzz-pollinating bees.
Dispersal: No observations recorded but probably similar to that described for G. superba.
Predation: No observations recorded.
Taxonomic notes: The growth form of this species, usually with a single stem, and 1-5 clusters of leaves toward the apex is a feature shared only by Gustavia grandibracteata, G.pubescens, and G. sessilis..
Conservation: IUCN Red List: Endangered C1+2a ver 2.3 (Mitré, M. 1998. Gustavia monocaulis. In: IUCN 2013. IUCN Red List of Threatened Species. Version 2013.2. www.iucnredlist.org. Downloaded on 20 March 2014.).
Uses: None recorded.
Etymology: The specific epithet refers to the monopodial growth form of the species. The individuals we have seen grow as an unbranched treelet with large leaves in clusters at the apex of the sterm.
