Distribution, ecology and phenology

Noronhia seyrigii occurs in low- to mid-elevation transitional forests and thickets, from Antsalova in the west to Fort-Dauphin in the south ( Fig. 49 View Fig ). It produces flowers and fruits throughout the year except in May.

Conservation status

Sixty-seven collections representing 58 localities were available for analysis, which yielded an EOO of 168,756 km 2, an AOO of 216 km 2, and 48 subpopulations representing 37 locations, of which 11 occur within protected areas (Amoron’i Onilahy, Analavelona, Andohahela, Behara-Tranomaro, Bemaraha, Beompa, Beza-Mahafaly, Pic d’Ivohibe, Tsimembo, and Zombitsy). Being widespread and occurring in many protected areas, N. seyrigii is assigned a preliminary status of “Least Concern”.

Notes

Noronhia seyrigii can be recognized by its non-woody, pubescent petioles, chartaceous, lanceolate leaf blades, red-brown tinged greenish flowers, and subglobose fruits with woody endocarp. This species closely resembles N. tropophylla from which it differs mainly by the flower color (red vs. white) and the presence of a corona. Because of the high degree of similarity between these two species and their partially overlapping distribution, identification of non-flowering material is difficult and often inaccurate. Noronhia seyrigii was based on the following syntypes: Humbert 12375, 12445, 12808, 12955 and 13227, Perrier de la Bâthie 12715, 17362 and 19259, Seyrig 22a, 22b, 22c and 22 (=Herb. Jard. Bot. Tan. 6101). Of these specimens, Humbert 12375 and Seyrig 22b have the most complete material and are represented by the most duplicates, therefore one of the sheets of Seyrig 22b at P has been chosen as the lectotype since the species is named after André Seyrig (1897-1945), a French civil engineer and renowned naturalist who worked extensively in southern Madagascar. PERRIER DE LA BâTHIE (1949) mentioned Humbert 1322 as one of the syntypes in the protologue. However, this is a typographical error for Humbert 13227, which he later corrected in the “Flore de Madagascar et des Comores ” volume ( PERRIER DE LA BâTHIE, 1952). Likewise, Seyrig 22a is listed as a syntype but it could not be located at the Paris herbarium . Interestingly, there are two specimens numbered Seyrig 22 ( P [ P 03559277 , P 03559278 ]!), of which only one bears the mention “ex Herbier du Jardin Botanique 6101 ” ( P [ P 03559277 ]), yet there is also another specimen explicitly numbered Herb. Jard. Bot. Tan. 6101 ( P [ P 03559280 ]!). It is thus possible that both duplicates of Seyrig 22 correspond to Seyrig 22a, as listed by PERRIER DE LA BâTHIE (1949), or at least the duplicate without any reference to Herb. Jard. Bot. Tan. 6101, namely Seyrig 22 ( P [ P 03559278 ]). Given these facts, Seyrig 22a should not be regarded as a syntype .
