Distribution, ecology and phenology

Additional specimens examined

Noronhia lanceolata   occurs in low- to high-elevation dry forests and thickets in the south, from Sakaraha to Andohahela ( Fig. 27). It produces flowers and fruits throughout the year except in August and September.

There were 31 collections representing 29 localities available for analysis, which yielded an EOO of 26,232 km 2, an AOO of 104 km 2, and 20 subpopulations representing 17 locations, of which seven occurs within protected areas (Amoron’i Onilahy, Andohahela, Behara-Tranomaro, Beompa, Corridor Parcel I-Parcel II, Extension Ampalamora, and Vohidava-Betsimalaho). With an actual AOO likely much larger than 2,000 km 2, many locations and good representation within the network of protected areas, Noronhia lanceolata   is assigned a preliminary status of “Least Concern”.

Noronhia lanceolata   can be recognized by its rugose bark, non-woody petiole, lanceolate leaf blades, and white flowers lacking a corona. It differs from N. alleizettei   by its non-woody (vs. woody) petioles, lanceolate (vs. narrowly elliptic) leaf blades, thyrsoid inflorescences (vs. fasciculate flowers), cupuliform (vs. urceolate) corolla, and larger (26 3 22 mm vs. 13 3 13 mm) fruits. The description of this species was based on the following syntypes: Decary 4299, 4522, 4561, 4564 and 4649, Herb. Jard. Bot. Tan. 5108, Humbert 5124, 6765, 12792, 12813 and 13012, Perrier de la Bâthie 8821 and 19243, and Seyrig 23. The choice of a sheet of Perrier de la Bâthie 19243 at P as the lectotype is based on its completeness and quality as well as the presence of duplicates in various other herbaria.

The specimen Humbert 6765 ([P04078609]) includes three fragments, of which two are assigned to N. lanceolata   and one to N. divaricata   . Moreover, PERRIER DE LA BâTHIE (1949) listed Decary 4561 as one of the syntypes of N. lanceolata   , but no such specimen was found under Noronhia   at the Paris herbarium. In fact, the only specimen found of Decary 4561 is clearly not a Noronhia   , having been identified as Desmodium repandum (Vahl) DC.   (P [P0009323]!). Besides, this specimen was collected in humid forest at Farafangana, far north from the range of N. lanceolata   and outside of its natural habitat. However, it is possible that a numbering mistake was made since Decary 4561 was collected on August 8, 1926 in Farafangana, six days after Decary 4564 was collected in Fort-Dauphin, suggesting that perhaps another specimen bearing the number Decary 4561, truly representing N. lanceolata   , exists. Nevertheless, in the absence of such a specimen and given the presence of material belonging to Desmodium Desv., Decary   4561 should be treated as an excluded syntype.
