Morphology General Habit

Perennial subshsrub; stems wiry and somewhat woody, much twining, pubescent when young, purplish-brown when old

Morphology Leaves

Leaves small, up to 2.5 (– 4.5) × 2 cm, ovate, subcordate, shortly mucronate, shortly petiolate, paler and pubescent beneath

Morphology Reproductive morphology Inflorescences

Inflorescence sessile or nearly so; sepals c. 2 mm long and wide, rounded, pubescent; corolla white, c. 0.8 – 1.2 cm long, the midpetaline bands often dull lilac.

Distribution

A plant of dry bushland at altitudes below 600 m, most common in Central America and the Caribbean (absent from Cuba) and in South America in four areas: the dry Caribbean coastal region of Venezuela and Colombia, the Caatinga region of NE Brazil, NW Peru and adjacent parts of Ecuador; the Chiquitania of Bolivia.

Conservation

In Bolivia this species should be categorised as Vulnerable (VU) based on its extent of occurrence of 19,340.376 km2. Populations are scattered and consist of few individuals. However, its occurrence as a component of secondary scrub suggests it faces no immediate threat, although the habitat is being degraded and there is a risk that it might be cleared to create rough pasture. In Peru this species should be categorised as Endangered (EN) based on both its extent of occurrence of 1,229.177 km2 and area of occupancy of 16,000 km2 but this will need to be revised after populations have been carefully studied.

Phenology

This is a winter flowering species collected in Bolivia from April to July and in Peru from June to August.
