6. Leptolaena multiflora Thouars 

Hist. Veg. Isles Austral. Afriq.: 41, t. 11 (1805).Type: Thouars s. n., Madagascar, without precise locality (P!).

As here recognized, Leptolaena multiflora  occurs primarily in coastal forest mostly on sand, with a few populations recorded farther inland, probably on similar substrates (Fig. 2). In the past, this species has been broadly circumscribed to include all of the new taxa described here, as well as the Sambirano endemic L. cuspidata  . As defined here, L. multiflora  can be distinguished by its glabrous, elliptic, usually almost equilateral leaves, the largest of which usually exceed 5.5 cm in length and dry an olive green to brownish color. In addition, the sepals at anthesis exceed the involucre teeth by (0 - 8 -) 1 - 1.8 mm, a feature that separates L. multiflora  from L. abrahamii  .

Vernacular names.Amaninombilahimena, Amaninombilahy, Amaninombilahy a petites feuilles, Anjananjana, Birana, Dilatra, Dilatry Lahy, Fotona, Fotona Beravina, Fotonala, Hazoambo, Hazomasy, Helana, Jana, Manilombilahy, Manina ombilahy, Sarifatra, Tsilaitra a petites feuilles.

Conservation status.Despite an extent of occurrence and area of occupancy far in excess of 20,000 km 2 and 2,000 km 2 respectively, with only four of c. 19 sub-populations occurring in protected areas, and thus indicating a possible population reduction in the next three generations of> 50 %, L. multiflora  is assigned a preliminary status of Endangered (EN).
