Trees 5-20 m tall, 5-54 cm DBH, bark with white milky latex; young twigs ferruginous pubescent. Leaves alternate; blades oblanceolate to obovate or elliptic to narrowly elliptic or narrowly oblong, 3-15 3 1.5-5 cm, coriaceous, apex emarginate, retuse, or shortly acuminate, sometimes truncate, margin entire, base acute to cuneate or obtuse, adaxial surface ferruginous pubescent when young, later glabrescent or pubescent only on the midvein, abaxial surface pubescent, venation craspedodromous, midvein prominent abaxially, secondary veins 10-20 pairs, arcuate, 2-10(-15) mm apart, prominent on both surfaces, tertiary veins raised on both surfaces; petiole 5-15 mm long, canaliculate on adaxial surface, pubescent, sometimes glabrescent. Inflorescence axillary or terminal, a panicle, 3-8 cm long, axes terete, tomentose. Male and female flowers 5-merous; pedicel 0-0.3 mm long, pubescent; calyx lobes deltate to ovate, 1.2-1.5 3 1-1.5 mm, imbricate, adaxial surface glabrous, abaxial surface pubescent, persistent on fruit; corolla lobes ovate, 2-3 3 1-1.2 mm, imbricate, adaxial surface pale yellow, glabrous, abaxial surface brown, pubescent; stamens 5. Male flowers with filaments 1 mm long, glabrous, white, anthers 0.6-0.8 mm long, ovoid, yellow, glabrous; disk 1-1.2 mm in diam., pubescent; ovary rudimentary. Female flowers with filaments c. 0.8-1 mm long, glabrous, white, anthers c. 0.5-0.6 mm long, subglobose or ovoid, sterile, yellow, glabrous; disk 1.5-2 mm in diam., pubescent; ovary widely to very widely ovoid, c. 1-1.2 3 1 mm, pubescent, placentation subapical; style very shortly trifid, apical, 0.3-0.4 mm long, covered with indument. Fruits 1.5-2.5 3 0.8-1.5 cm, ellipsoid, very often glabrate or glabrescent, rarely completely glabrous, with longitudinal striations.

“Ditimena’’, “Menavahatra’’, “Tandraviravy’’ (North East).

Abrahamia thouvenotii   occurs mainly in eastern Madagascar and the Sambirano region (Map 10). It is found principally in mid-elevation rainforests at an elevation between 800 and 900 m, although a few subpopulations have been recorded at much higher elevations. Flowers have generally been collected from August to October, although some individuals may flower as early as July. Fruits have been recorded between November and January.

134 Conservation status


Additional material examined

With an EOO of 116,472 km 2, a minimum AOO of 180 km 2, and 46 recorded localities, with subpopulations in at least 10 protected areas (Anjanaharibe-Sud, Makira, Manongarivo, Mantadia, Marojejy, Masoala, Montagne d’Ambre, Analamazaotra, Ranomafana, and Zahamena), A. thouvenotii   is assigned a preliminary conservation status of “Least Concern’’ [LC] using the IUCN Red List Categories and Criteria ( IUCN, 2012).

Abrahamia thouvenotii   can be distinguished from other members of the genus by the presence of widely spaced secondary leaf venation and indument on the ovary and disk. Three collections from northern and northeastern Madagascar (Miller 3625, Service Forestier 15067 and Ursch 195) differ from typical material by having flowers with a glabrous disk. Additional collections from this area, especially from female individuals, will be needed, however, to determine whether they may represent a distinct taxon. Until such time, we have chosen to include them in our circumscription of A. thouvenotii   .

PERRIER DE LA BâTHIE (1944) cited two collections in the protologue of Protorhus thouvenotii   , one in bud (Thouvenot 7) and the other in fruit (Thouvenot 80). We have designated a sheet of Thouvenot 80 as the lectotype because it is represented by two additional specimens, whereas there is only a single sheet of Thouvenot 7.

Protorhus lecomtei   (≡ Abrahamia lecomtei   ) was based on two collections that belong to different taxa, one of which (Perrier de la Bâthie 5283) we have placed in A. thouvenotii   . As indicated above under A. lecomtei   , we have designated a specimen of the other syntype gathering, Perrier de la Bâthie 14301, as the lectotype in order to retain a circumscription that includes the additional material assigned by PERRIER DE LA BâTHIE (1944) to Protorhus lecomtei   .
