Distribution, ecology and phenology

Noronhia capuronii occurs in low- to mid-elevation dry forests in the north, from Montagne des Français to Ankarana and Daraina ( Fig. 3 View Fig ). It produces flowers and fruits from October to June.

Conservation status

With 14 collections representing 14 localities, the assessment resulted in an EOO of 4,885 km 2, an AOO of 52 km 2, and 12 subpopulations representing seven locations, of which five occur within protected areas (Ankarana, Loky-Manambato, Montagne d’Ambre, and Montagne des Français). Noronhia capuronii is assigned a preliminary status of “Vulnerable” [VU B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v)], due to continuing decline in AOO, number of both locations and mature individuals, and in habitat quality resulting from deforestation, charcoal production, and illegal and/or artisanal mining.


Noronhia capuronii can be recognized by its chartaceous, cordate leaf blades, pubescent petiole and midvein, thyrsoid inflorescences with green-orangish flowers and subglobose fruits. It differs from N. jeremii Hong-Wa & Callm. and N. richardii Hong-Wa by its ovate (vs. linear to oblong in N. jeremii and lanceolate to oblong in N. richardii ) leaf blades, pubescent (vs. glabrous) inflorescences and greenish tinged orange (vs. yellowish and red, respectively) flowers.
