Antsiranana: Rég. Diana, NW, près de Ramena, 12°14’S 49°21’E,  9.XI.1961,  Service Forestier20083(holo-: P[ P06169101]!; iso-: G!, MO- 6684137!, NY!, P[ P00722667]!, TEF[ TEF000887]!).   Diagnosis   Abrahamia suarezensis Randrian. & Lowrycan easily be distinguished from other members of the genus by its small, narrow oblanceolate leaves (2.5-6.5 3  0.7-2.5 cm) with ascending secondary veins that form an acute angle with the midvein at the leaf base.   Description  Shrubsor trees 1.5-20 mtall, 6-40 cmDBH; young twigs waxy, lenticellate and pubescent at the very tip. Leavesopposite to subopposite; blades oblanceolate to obovate, 2.5-7.5 3 0.7-3.5 cm, subcoriaceous to chartaceous, apex rounded, retuse, or emarginate, margin entire, undulate, base acute to cuneate, adaxial surface glabrous, abaxial surface with sparse sericeous indument when young, glabrescent, venation craspedodromous, midvein slightly prominent abaxially, secondary veins 9-12 pairs, 1-5 mmapart, not very prominent abaxially but well defined, tertiary veins obscure on both surfaces; petiole 4-10 mmlong, canaliculate on adaxial surface, sericeous when young, glabrescent. Inflorescenceaxillary or terminal, a panicle (sometimes depauperate), 1.5-3.5 cmlong, the axes flattened, sericeous. Maleand female flowerswith a pedicel 0.5-1 mmlong, pubescent; calyx lobes very widely ovate, c. 1 3 1 mm, glabrous on both surface; corolla lobes ovate, 2.5-3 3 2 mm, imbricate, glabrous on both surfaces, yellow green or light yellow; stamens 4 or 5. Male flowers5-merous, filaments 1.5-2 mmlong, glabrous, white, anthers 1 mmlong, obloid to slightly ovoid, yellow, glabrous; disk 1 mmin diam., glabrous; ovary rudimentary. Female flowers4-merous, filaments c. 1.5 mmlong, glabrous, white, anthers c. 0.8 mmlong, ovoid, sterile, yellow, glabrous; disk annular, cupuliform, c. 1.5 mmin diam., glabrous; ovary very widely ovoid, 1 3 1 mm, glabrous, placentation apical or slightly subapical; style shortly trifid, latero-subapical or apical, 0.7-0.8 mmlong, glabrous, stigmas capitate. Fruits1.8-2.7 3 1-1.5 cm, ellipsoid, slightly asymmetrical, glabrous, with longitudinal striations.   Distribution, ecology and phenology   Abrahamia suarezensisis known only from far northern and northeastern Madagascar, from the vicinity of Antsirananato the area around Daraina and extending along the east coast to S of Vohémar ( Map 8). It appears to occur primarily in coastal sandy dune forests although several collections have been made in dry forest on other substrates in the Daraina area (i.e., to the W of Vohémar). Flowering material has been collected in October and November, and fruits are known from November and December.   Conservation status With an EOO of 9,014 km 2, a minimum AOO of 116 km 2, and 35 recorded localities, with subpopulations in 3 protected areas (Loky Manambato, Oronjia, and Montagne des Français), representing c. 23 locations,  A. suarezensisis assigned a preliminary conservation status of “Least Concern’’ [LC] using the IUCN Red List Categories and Criteria ( IUCN, 2012).   Notes   Abrahamia suarezensismost closely resembles  A. patrickii,from which it differs by having leaves with fewer secondary veins (9-12 vs 24-28) that are widely (vs closely) spaced, and shorter petioles (4-10 vs 6-13 mm). Typical material of this species from dunes in the area around Antsirananahas narrowly obovate to oblanceolate leaves up to 5 cmlong, but collections from farther South near Daraina and Mahavanona have more broadly obovate leaves that can reach 5-7 cmin length, as well as slightly larger fruits. While these differences appear to show some geographic structuring, we have chosen to refrain from recognizing the larger-leaved material from the South as a distinct taxon because no clear limits can be seen between the forms and certain specimens bear leaves spanning the range of variation in both shape and size.    Paratypi   MADAGASCAR. Prov.
