Type
Type: Guyana, C. S. Parker s.n. in Herb. Lindley (holotype CGE 14419!; isotypes K!).
Morphology General Habit
Twining perennial herb, completely glabrous in all parts
Morphology Leaves
Leaves petiolate, divided into 5 (– 7) separate sessile leaflets, leaflets 2 5 – 6 × 0.1 – 0.4 (– 0.7) cm, linear to narrowly oblong, apiculate, acuminate at base; petioles 0.5 – 5 cm
Morphology Reproductive morphology Inflorescences
Inflorescence of 1 (– 3)-flowered, axillary, pedunculate cymes; peduncles slender, 0.8 – 1.8 cm, often flexuose; bracteoles 1.5 mm, deltoid, caducous; pedicels 1 – 1.5 cm, stouter than peduncles; sepals subequal, 5 – 6 × 2 – 3 mm, ovate, shortly apiculate, pale green; corolla 4 – 6 cm, funnel-shaped, pink, glabrous, limb c. 4 cm diam., unlobed
Morphology Reproductive morphology Fruits
Capsule 12 – 14 cm long, ovoid, glabrous; seeds 5 – 6 mm, dark brown, nearly glabrous
Ecology
Widely distributed in wetlands in tropical South America from Colombia and the Guyanas south to northern Argentina but uncommon and often misidentified; also in Cuba. In Bolivia it is characteristic of small streams with moving water in open areas below 500 m, principally in the cerrado biome. It is very scattered in occurrence, usually in small populations and has been mostly collected along the Río Paraguá between Florida and El Refugio. It seems likely that it is more common than shown in Map 23, particularly as suitable habitas are common in the Beni and around the Pantanal.
Conservation
Least Concern (LC) but vulnerable to habitat change, particularly drainage of wetlands.
Note
Usually easily recognised by the very short sepals combined with the 5-foliolate leaves and relatively large glabrous flower. Flowers mostly towards the end of the rainy season from March to July.
