Eremolaena humblotiana is restricted to humid and subhumid evergreen forest at low and middle altitude, up to 1200(-1500) m, from the Brickaville to Vatomandry area, Betampona RNI, Zahamena RNI, and the area around Lac Alaotra (Fig. 1). It can be recognized by its large, subcoriaceous leaves with the venation distinctly raised on the lower surface, and its comparatively large flowers with sepals 15-19 mm long. With the exception of a recent collection from Zahamena RNI made in 1994, E. humblotiana has not been recorded from elsewhere in its range since 1957.
