Distribution, ecology and phenology

Noronhia louvelii occurs in low- to high-elevation humid forests in the east, from Daraina to Vatomandry and in the Centre-West near Tsiroanomandidy ( Fig. 27 View Fig ). It produces flowers and fruits throughout the year except in March.

Conservation status

Known from 61 collections representing 57 localities, Noronhia louvelii is quite widespread. With an EOO of 141,234 km 2, an AOO of 192 km 2, and 39 subpopulations representing 26 locations, of which 10 occur within protected areas (Analamazaotra, Anjanaharibe-Sud, Anjozorobe-Angavo, Betampona, Loky-Manambato, Makira, Marojejy, Masoala, Tsaratanana-Ambohimirahavavy-Corridor Marojejy, and Zahamena), it is assigned a preliminary status of “Least Concern”.


Noronhia louvelii can be recognized by its coriaceous, elliptic leaf blades, cupuliform, red flowers, and crustaceous, subglobose fruits subtended by short pedicels. It differs from N. luteola by its woody (vs. non-woody) petiole, elliptic (vs. oblong to ovate) leaf blades, cupuliform (vs. subrotate), red (vs. white) flowers, and crustaceous (vs. woody) endocarp. The collection Morat 4627 from humid forest around Tsiroanomandidy in the Bongolava region extends the range of this species to the west. A collection of another species bears the same number as the type specimen of N. louvelii : viz. Dalbergia maritima R. Vig. (holo-: Louvel 79 [P00060529], from eastern Madagascar).
