Distribution, ecology and phenology
Noronhia verticillata occurs in low- to mid-elevation humid forests in the Sambirano region and along the east, from Vohémar to Fort-Dauphin (Fig. 68). It produces flowers and fruits throughout the year except in April and May.
Conservation status
The assessment included 52 collections representing 45 localities and indicated an EOO of 195,817 km 2, an AOO of 164 km 2, and 36 subpopulations representing 27 locations, of which 13 occur within protected areas (Ampasindava, Analamazaotra, Andohahela, Anjanaharibe-Sud, Corridor Ankeniheny-Zahamena, Manongarivo, Marojejy, Masoala, Ranomafana, Tsaratanana, Tsitongambarika, and Zahamena). With such a large distribution and presence within many protected areas, N. verticillata is assigned a preliminary status of “Least Concern”.
Notes
Noronhia verticillata can be recognized by its verticillate leaves and somewhat punctate fruits. Although Noronhia cruciata and N. verticilliflora, both of which have verticillate leaves, were distinguished from N. verticillata by PERRIER DE LA BâTHIE (1949, 1952) based on a rotate corolla and verticillate flowers, respectively, they are placed here in synonymy because these character states fall within the range of variation of N. verticillata, as circumscribed here. PERRIER DE LA BâTHIE (1949, 1952) also mentioned the presence of four stamens and the absence of a corona in N. verticilliflora, which he only knew from the type specimen, but these features were not observed in any other collections and their presence is ambiguous in the type. Noronhia cruciata was based on four syntypes: Cours 1027, Perrier de la Bâthie 8810 and 18082, and Viguier 750. Perrier de la Bâthie 18082 has been chosen as the lectotype as it comprises the best material.
