Wood, J.R.I., Clegg, R. Jacquemontia (Convolvulaceae) in Bolivia and Peru. Kew Bull 76, 375–420 (2021). DOI: https://doi.org/10.1007/s12225-021-09936-5

Morphology General Habit
Twining herb, the stems leaves and calyx tomentose; stems woody below; leaves shortly petiolate, ovate, cordate, shortly acuminate
Morphology Reproductive morphology Inflorescences
Inflorescence of axillary pedunculate cymes; bracteoles linear c. 5 mm; sepals unequal, outer sepals ovate, cordate, acute c. 10 × 6 – 7 mm, strongly accrescent in fruit, inner sepals much smaller, c. 4 mm long; corolla blue.
Distribution
In Bolivia and Paraguay this is a plant of the Chaco region, growing in sandy and stony ground in seasonally dry, often open bushland from 150 – 650 m. In Bolivia, it is particularly characteristic of the Abayoy region around Taperas and Carmen Rivero Torres (Map 6). In Brazil it is mainly a plant of the caatinga in the north east; elsewhere growing in xerophytic vegetation of coastal Venezuela, neighbouring Guajira in Colombia and on the offshore Netherlands Antilles (Aruba, Curaçao) as well as in Puerto Rico and the neighbouring Virgin Islands.
Conservation
Least Concern (LC), based on its extent of occurrence, would seem correct as this species is locally abundant in an unthreatened habitat. A categorisation of Endangered (EN) based on an area of occupancy of 88,000 km2 is quite wrong as the number of collections do not represent its real local abundance.
