Fruiting pedicel 2-9 3 1.8-3.6 mm; young fruits green, reddish black when mature, ovoid to subglobose, 12-31 3 8.5-26 mm, surface smooth, sometimes covered with a white pellicle, apex flat to bluntly pointed or apiculate; dry pericarp 1.3-4.2 mm thick; endocarp woody; seed 11.5-21.5 3 7-18 mm.
Distribution, ecology and phenology
Noronhia edentata occurs in low- to high-elevation humid forests in the east, from Sambava to Ambondrombe (Fig. 19). It produces flowers and fruits from September to May.
Conservation status
The assessment was based on 27 collections representing 19 localities, resulting in an EOO of 38,642 km 2, an AOO of 68 km 2, and 13 subpopulations representing 12 locations, of which six occur within protected areas (Analamazaotra, Betampona, Makira, Makirovana, Masoala, and Zahamena). Being widespread and present in many protected areas, Noronhia edentata is assigned a preliminary status of “Least Concern”.

Notes
Noronhia edentata can be recognized by its leaves, which have broadly elliptic blades and long, woody petioles, its white greenish flowers and its large fruits, with thick pericarp. There is a slight leaf heteroblasty in this species. In particular, the leaf base is narrower and the acumen longer (up to 15 mm long) in seedlings and saplings than in adult plants. This taxon was previously recognized as a variety of N. emarginata, from which it differs by its habit, leaf shape, and flower color and shape. Moreover, these two entities belong to separate clades (HONG- WA & BESNARD, 2013, 2014). PERRIER DE LA BâTHIE (1949) described N. emarginata var. edentata based on the following syntypes: Perrier de la Bâthie 8809, Thouvenot 58 and Ursch 820; the latter is a typographical mistake for Ursch 82. The overall quality and completeness of Perrier de la Bâthie 8809 justify the selection of one of the specimens at P as the lectotype.
