DISTRIBUTION AND HABITAT. — Scolopia madagascariensis occurs in littoral forest along the northern part of the eastern coast of Madagascar, with most collections coming from Masoala ( Fig. 6 ); it has been reported on sand and laterite. A single collection from the province of Fianarantsoa (Service Forestier 14753, Ambodilafakely, Ampasinambo, Nosy-Varika, 22.X.1954, fr.; P×2) resembles S. madagascariensis , but as it is both outside the otherwise-known geographic range and probably from a locality well inland, its identity is questionable; it might be a highly aberrant specimen of S. hazomby .

REMARKS

Scolopia madagascariensis belongs to the group of littoral species with usually greenish-drying leaves. It is distinguished by its large, broadly elliptical to elliptical leaves, which are usually less than twice as long as broad and usually have a cuspidate apex and broadly convex to rounded base. It is most similar to S. orientalis , a widespread species that has proportionately narrower, sometimes somewhat oblong leaves with attenuate to cuneate or convex bases; leaf apices in S. orientalis are highly variable but only seldom cuspidate. Scolopia madagascariensis also bears a superficial resemblance to the typically broad-leaved S. manongarivae , a species of humid forests, often found at high elevation; that species has pubescent sepals that are noticeably accrescent in fruit. At the time of Sleumer’s (1972a) revision few specimens of S. madagascariensis as herein circumscribed were available, and most of the specimens that he placed within S. madagascariensis are herein transferred to S. hazomby . Scolopia hazomby has narrower, often somewhat oblong, usually acuminate leaves, which usually dry brown; it generally occurs in low- to mid-elevation humid forests.

CONSERVATION STATUS

Scolopia madagascariensis is known from seventeen locations and has an Extent of Occurrence of 22 166 km 2. However, it is restricted to littoral forest, a highly threatened ecosystem of which only fragments remain, and has a small minimum Area of Occupancy of 88 km 2. The degree of fragmentation suggests that S. madagascariensis be assigned a preliminary assessment of Vulnerable (VU B2ab(iii)). The species is fairly common in the Protected Area of Masoala.
