– Protorhus ditimenavar. lanceolataH. Perrierin Mém. Mus. Natl. Hist. Nat. 18: 261. 1944[nom. inval.].
Typus: MADAGASCAR. Prov. Antsiranana: Rég. Analanjorofo, N de Nosiarina(basse Bemarivo), [ 14°14’30’’S 50°03’30’’E], 50 m, 7.XII.1966, fr., Service Forestier27167(holo-: P[ P06775145]; iso-: G[ G00341713]!, MO-6684136!, P[ P00580350]!, TEF[ TEF000885]!).
Diagnosis Abrahamia lenticellata Randrian. & Lowrymost closely resembles A. ditimenabut differs by having chartaceous (vs coriaceous) leaves with an acuminate or shortly acuminate apex (vs emarginate or retuse) and semicraspedodromous (vs craspedodromous) secondary veins.
Description Trees 5-20 mtall, 10-35 cmDBH, bark with white milky latex; young twigs glabrous or with ferruginous pubescence, with lenticels, waxy. Leavesalternate or subopposite; blades obovate or oblanceolate, 2.5-8(-14.5) 3 1.2-4 cm, chartaceous, apex shortly acuminate or acuminate, rarely rounded, margin sometimes undulate, base cuneate, adaxial surface glabrous, abaxial surface with sparse short, appressed indument, sometimes glabrous, venation semicraspedodromous, midvein prominent abaxially, secondary veins 20-25 pairs, 1-5 mmapart, slightly prominent abaxially, tertiary veins raised on abaxial surface; petiole 7-13 mmlong, 0.5-1mmin diam., canaliculate on adaxial surface, glabrous. Inflorescenceaxillary or terminal, a panicle or sometimes a thyrse, 1-4 cmlong, axes terete, pubescent. Maleand female flowers4-merous (rarely 5-merous), small, c. 2 mmlong; pedicel c. 0.5-0.8 mm, scabrous; calyx lobes deltate to triangular, c. 1 3 1-1.5 mm, valvate, adaxial surface glabrous, abaxial surface pubescent, persistent on fruit; corolla lobes ovate, 2-2.5 3 1-2 mm, imbricate, adaxial surface glabrous, light yellow or cream, abaxial surface pubescent; stamens 4. Male flowerswith filaments 1-1.2 mmlong, white, glabrous, sometimes with sparse trichomes toward the base, anthers 0.5 mmlong, ovoid to subglobose, yellow, glabrous; disk 1-1.5 mmin diam., glabrous; ovary rudimentary. Female flowerswith filaments c. 0.5 mmlong, pubescent, anthers 0.2-0.3 mmlong, sub-spherical, sterile, brown, glabrous; disk c. 2 mmin diam., slightly cupuliform, glabrous; ovary depressed ovoid, 1 3 1.1 mm, pubescent, slightly asymmetrical, style short, thick, pubescent, c. 0.3-0.4 mmlong, stigmas capitate. Fruits2-2.6 3 1.3-1.5 cm, ellipsoid to ovoid, slightly asymmetrical, surface velutinous, with longitudinal striations.
Vernacular names “Hazombarorana’’, “Hazombarorana à petite feuille’’, “Sandramy mena’’.
Distribution, ecology and phenology Abrahamia lenticellataoccurs in eastern rainforest ( Map 6) at elevations from sea level to 1200 m. Material in flower has been collected between August and October, and fruits have been gathered in November and December.
Conservation status With an EOO of 69,556 km 2, a minimum AOO of 104 km 2, and 28 recorded localities, with subpopulations in at least 11 protected areas (Zahamena, Betampona, Ambalabe, Pic d’Ivohibe, Ranomafana, Analamazoatra, Makira, Nosy Mangabe, Masoala, Anjanaharibe-Sud, and Marojejy) that comprise about 22 locations, A. lenticellatais assigned a preliminary conservation status of “Least Concern’’ [LC] using the IUCN Red List Categories and Criteria ( IUCN, 2012).
Notes Material attributable to this species was assigned by PERRIER DE LA BâTHIE (1944, 1946) to an invalidly published variety of Protorhus ditimena(≡ Abrahamia ditimena). Despite an unquestionable similarity to that species, A. lenticellataclearly warrants recognition at the species level, differing from A. ditimenain having leaves with an apex that is almost always acuminate, sometimes shortly so (vs emarginate or retuse) and whose blades are chartaceous (vs coriaceous) in texture.
