Distribution, ecology and phenology Noronhia pervilleana occurs in low- to high-elevation dry to humid forests from around Anivorano-Nord in the north to around Bemaraha in the west (Fig. 49). It produces flowers and fruits year-round. Conservation status There were 40 collections representing 30 localities available for analysis, which resulted in an EOO of 114,822 km 2, an AOO of 112 km 2, and 21 subpopulations representing 20 locations, of which 11 occur within protected areas (Andavakoera-Ambohipiraka, Ankarana, Bemaraha, Galoko, Lokobe, Loky-Manambato, Manongarivo, Marojejy, and Tsaratanana). With a large EOO, an actual AOO that likely exceeds 2,000 km 2, and several locations, half of which are in protected areas, N. pervilleana is assigned a preliminary status of “Least Concern”. Notes Noronhia pervilleana can be recognized by its partially woody petiole, glossy leaf blades, with undulate margins, rotate, white corolla, and rostrate fruits. It differs from N. marojejyensis, as discussed under that species, mainly by the texture of their petioles, the shape of their leaves, flowers and fruits, the color of their corolla, and the apex of their fruits. This species was based on three syntypes (Pervillé 281, 447 and 459), none of which is extant at the herbarium in Berlin (B). Although no holotype was designated in the protologue, a sheet of Pervillé 447 in Berlin was apparently annotated as the type, according to a handwritten note on the sheet at L ([L0005393])(Fig. 48). The annotation may not be that of Knoblauch himself, but it is nonetheless very likely that this specimen was part of the original material he used for the species description. Since it is also a more complete specimen and is represented by more duplicates than Pervillé 281, it has therefore been chosen as the lectotype. There is some confusion regarding Pervillé 459, which has been annotated as the type in some herbaria. However, this specimen is actually numbered Pervillé 459ter or even Pervillé 459 quater (459 4ter [sic]), with duplicates distributed from Paris to a dozen herbaria long after the species was described. Thus, it is by no means certain that Knoblauch saw specimens of Pervillé 459ter and 459 4ter, or that the material numbered Pervillé 459, 459ter and 459 4ter is all the same thing. Given these uncertainties, the choice of Pervillé 447 as the lectotype seems appropriate. Additional specimens examined MADAGASCAR. Prov.
