description: Vitex cauliflora Moldenke in Phytologia 3: 432. 1951.
Holotypus: MADAGASCAR. Prov. Toamasina: env. de la Baie d’Antongil, X.1912, fl., Perrier de la Bâthie 10311 (P [P00100756]!; isotype: P [P00084315]!).
Notes. – With the exclusion of the two varieties that we treat as distinct species, we limit V. cauliflora to plants that correspond to the typical variety. Vitex cauliflora can be recognized by its sub-coriaceous, medium-size unifoliolate leaves (8-17 × 3-5 cm) and its beige-brown villous inflorescences including the corolla (Table 1). This species is confined to low to midelevations evergreen forests in northeastern Madagascar.
Conservation status. – Vitex cauliflora is known from 15 locations, 9 of which are encompassed in the protected area network (within Anjanaharibe-Sud, Mananara-Nord, Makira, Marojejy and Masoala). With an EOO of c. 13,670 km 2 and an AOO of 60 km 2, V. cauliflora is therefore assigned a preliminary IUCN conservation status of “Least Concern” [LC].
