Bull. Soc. Bot. France 80: 200 (1933). — Type: Perrier de la Bâthie 4502, Prov. Mahajanga, Forêt d’Analamaitso, vers 900 m, Aug. 1907, bud, fl. (holo-, P!) .

Brexia decurrens is a poorly known cauliflorous shrub in subhumid forest, known from only 2 localities (Analamaitso RS and Menaloha) (Fig. 2); it has not been collected since 1938. This species can be distinguished from B. coursiana by its stouter peduncle greater than 1 mm broad, with short secondary axes that branch close to the apex to form a corymb, an irregularly lobed to entire calyx, and petaloid disc segments with a crenulate margin.

CONSERVATION STATUS. — With an EO of less than 2000 km 2, an AO of 200 km 2, and only 2 subpopulations, only 1 of which is encompassed within the Anlamaitso protected area, Brexia decurrens is assigned a preliminary status of Endangered (EN B1ab2ab).
