  • Description

    Description - Leaf blades oblanceolate to obovate, acute at base, LAV ca. 3:1. Inflorescences single pauciflorous axes to sparsely flowered thyrsoid panicles with a pair of basal branches; bracts subtending basal branches narrowly triangular. Corollas campanulate with reflexed lobes, 25-30 mm long; tube ventricose at base, 13-18 × 9-10 mm (at base); lobes 1/3-1/2 of corolla length, 7-10 mm long. Stamens with filaments 5-6 mm long; anthers lanceolate, acute at apex, 11.5-12.5 × 2.2-2.5 mm. Pollen exine regularly foveolate. Style 20-22 mm long; immature fruits ovoid-elliptic. Capsules narrowly obovoid, 18-24 × 8-12 mm. Seeds 1.33-1.5× 0.37-0.53 mm.

  • Discussion

    Variety condamineoides differs from var. thyrsiflora in having oblanceolate, basally acute (vs. oblong, basally truncate) leaf blades (Fig. 42A), larger and less constricted corollas with reflexed (vs. sub-erect) lobes, and larger anthers. The inflorescences of var. condamineoides are quite variable, ranging from pauciflorous to multiflorous panicles, with lateral cymules ranging from single-flowered to few flowered; all the possible intergradations were found throughout the specimens examined. Unfortunately, in Bernardi 5829 (var. thyrsiflora) only young capsules are available, so to it was impossible to reliably compare the fruits of these two varieties.

  • Distribution

    Lowland rain forests and cloud forests of medium elevations, in association with Gyranthera caribensis and Iriartea fusca, 100-1400 m, along the Coastal Cordillera of Venezuela and the forested slopes of Tobago. Flowering specimens were collected in August, November, and December. Specimens with mature capsules have been collected in July and December.
