Noronhia tropophylla   occurs in low- to mid-elevation dry forests and woodlands from the Sofia region in the northwest to Ihosy in the south ( Fig. 62). It produces flowers and fruits throughout the year except in September.

Noronhia tropophylla   is a widespread species occurring at 29 localities scattered from the northwest to the south. With an EOO of 250,483 km 2, an AOO of 112 km 2, and 25 subpopulations representing 22 locations, of which eight occur within protected areas (Ankarafantsika, Baie de Baly, Beanka, Bemaraha, Corridor Bongolava, Menabe-Antanimena, and Sahamalaza-Iles Radama), N. tropophylla   is assigned a preliminary status of “Least Concern”.

Noronhia tropophylla   can be recognized by its non-woody petioles, oblong to lanceolate leaf blades often bearing domatia, white, subrotate flowers that lack a corona, and subglobose fruits. It closely resembles N. seyrigii   but differs from it by features discussed earlier under that species, mainly flower color and presence/absence of a corona. Noronhia tropophylla   exhibits slight variations in the narrowness and texture of the leaf blades that may be linked to different environments. PERRIER DE LA BâTHIE (1949, 1952) used these variations as a basis for recognizing two varieties, which are not adopted here. In any case, the varietal name Linociera tropophylla var. angustata   was not validly published because it was not accompanied by a Latin diagnosis (Art. 39.1; MCNEILL et al., 2012).

The following syntypes were used as a basis for Noronhia tropophylla: Herb. Jard. Bot. Tan.   6145, Humbert & Swingle 4895, Perrier de la Bâthie 1010, 1725, 1791, 8830, 8831, 8832, 8833, 8834, 12340 and 16564, and Service Forestier 5 and 28, the latter probably a mistake for Service Forestier 8. One of the sheets of Perrier de la Bâthie 12340 at P has been chosen as the lectotype because of its overall completeness and quality.

Two collections bearing the same number Perrier de la Bâthie 8830, probably due to a numbering mistake, are recognized respectively as Linociera tropophylla   (P [P03559131]!) and Noronhia boinensis   (P [P007010251, P04046995]). Similarly, P has two duplicates of Herb. Jard. Bot. Tan. 6145 (P [P03559126, P03559271]), one of which was identified as L. tropophylla   (P [P03559126]) and the other as N. seyrigii   (P [P03559271]), although the number is cited as L. tropophylla   in the protologue (PERRIER DE LA BâTHIE, 1949). In addition, while the labels indicate Bemaraha (western Madagascar) as the place of collection, Perrier de la Bâthie corrected the locality on the one he identified as N. seyrigii   (P [P03559271]), indicating that it was in fact collected at Ampandrandava (southern Mad-

agascar): “Localité probablement erronnée – spécimen provenant probablement d’Ampandrandava et des récoltes de Seyrig”. He nevertheless again cited Bemaraha as the place of collection for this number in both the protologue and the “Flore de Madagascar et des Comores ” volume (PERRIER DE LA BâTHIE, 1949, 1952).
