Ξ Vitex cauliflora var. longifolia Moldenke in Phytologia 3: 433. 1951 View in CoL [non V. longifolia Merr. View in CoL ].

Holotypus: MADAGASCAR. Prov. Toamasina: “ Passimbé ”, 27.XII.1881, fl., Humblot 90 ( P [ P00440350 ]! ; isotype: P [ P00440351 ]!) .

Notes. – Vitex humblotiana can be easily recognized by its very large (25-43 × 4.5-8.5 cm), unifoliolate, coriaceous leaves and its cauliflorous inflorescences with pubescent pedicels, bracts and calyx and yellow strigose corolla (see Table 1 View Table 1 ). This species is confined to low to mid-elevation evergreen forests in east-central Madagascar.

Conservation status. – Vitex humblotiana is known from 9 locations and five are encompassed in the protected area network (Analalava, Betampona and Zahamena). The species is threatened by habitat degradation due to forest exploitation, tavy and bush fires, especially in areas that are not formally protected. With an EOO of c. 14,760 km 2 and an AOO of 40 km 2, V. humblotiana is assigned a preliminary IUCN conservation status of “Vulnerable” [VU B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v)].
