Noronhia jeremii is named after Jérémie “Jimmy” Razafitsalama, a botanist working for the Missouri Botanical Garden in Madagascar, who collected the type material with the second author of this species. Jimmy was part of a team that undertook botanical inventories between 2005 and 2008 to explore the flora and vegetation in a long-neglected region of low- to high-elevation humid forest in northern Madagascar. These field expeditions led to the discovery of at least 20 new species in various families (CALLMANDER et al., 2008, 2009, 2012; WAHLERT, 2016).

Distribution, ecology and phenology

Noronhia jeremii occurs in low- to mid-elevation humid forests on sandstones and basement rocks in northern Madagascar, from Makira in the east to Kalobinono [previously called Kalabenono] in the west ( Fig. 27 View Fig ). It produces flowers and fruits from August to November.

Conservation status

The assessment, which was based on six collections representing six localities, resulted in an EOO of 796 km 2, an AOO of 16 km 2, and three subpopulations representing two locations, of which only one occurs within a protected area (Galoko). The third location sits outside the new protected area of Makira, where forests are potentially subject to exploitation leading to a reduction in habitat quality. Therefore, N. jeremii is assigned a preliminary status of “Endangered” [EN B1ab(iii)+2ab(iii)].

138 Boissiera 70


Noronhia jeremii can be recognized by its long, broadly linear leaf blades, petioles that are attached to the lower surface of the leaf blades, flowers lacking a corona, and apiculate fruits. It differs from N. capuronii by its glabrous (vs. pubescent) petioles, linear to oblong (vs. ovate) leaf blades, and woodier endocarp.
