description: 34. <i>Abrahamia viguieri</i> (H. Perrier) Randrian. &amp; Lowry, comb. nova. ≡ <i>Protorhus viguieri</i> H. Perrier in Mém. Mus. Natl. Hist. Nat. 18: 262. 1944. Lectotypus (designated here): MADAGASCAR. Prov. Toamasina: Rég. Alaotra-Mangoro, Moramanga, forêt d’Analamazaotra, [18°56’S 48°26’E], 1000 m, 19.X.1912, fl., <i>Humbert &amp; Viguier 815</i> (P [P00580348]!; iso-: K, MO- 6684877!, P [P00580349, P02141537, P06242027]!). <b>Description</b> <i>Trees</i> 2-25 m tall, 10-15 cm DBH; young twigs lanate. <i>Leaves</i> alternate, sometimes verticellate; blades oblanceolate, 8- 30 <b>3</b> 2-6 cm, chartaceous, apex acuminate, margin slightly revolute, base acute or cuneate, adaxial surface lanate, abaxial surface pubescent or lanate only on midvein, venation craspedodromous, midvein prominent abaxially, secondary veins 30-40 pairs, 2-15 mm apart, prominent abaxially, tertiary veins visible on both surfaces; petiole 5-20 mm long, canaliculate on adaxial surface, lanate. <i>Inflorescence</i> axillary, a panicle, 3-11 cm long, axes terete, villous or lanate. <i>Male</i> and <i>female flowers</i> 5-merous, glabrous; pedicel 0.2-0.3 mm long, villous; calyx lobes triangular, 0.5 <b>3</b> 0.5-0.7 mm, imbricate, adaxial surface glabrous, abaxial surface pubescent to lanate, persistent on fruit; corolla lobes ovate, 2 <b>3</b> 1 mm, imbricate or quincuncial, adaxial surface glabrous, abaxial surface pubescent on the longitudinal main axis; stamens 5; disk c. 1-1.2 mm in diam., pubescent. <i>Male flowers</i> with filaments 1.5 mm long, anthers 0.5 mm long, ovoid to subglobose, yellow, glabrous; ovary completely absent. <i>Female flowers</i> with filaments 0.5-0.7 mm long, anthers 0.3- 0.5 mm long, ovoid, sterile, yellow, glabrous; ovary widely depressed ovate, 1-1.2 <b>3</b> 0.8-1 mm, glabrous, placentation subapical, style simple (or with a minute trace of division), apically inserted, 0.5-0.7 mm long, glabrous; stigma 4-lobed, capitate. <i>Fruits</i> 3 <b>3</b> 1.5 cm, ellipsoidal, symmetrical or very slightly asymmetrical, glabrous, with longitudinal striations. <b>Etymology</b> The species is dedicated to Dan Turk, a forest botanist who has contributed tremendously to our knowledge of the trees of Ranomafana National Park. <b>Vernacular names</b> “Lambafohala’’, “Natoboka’’, “Sefana’’, “Tsitsebona’’. <b>Distribution, ecology and phenology</b> <i>Abrahamia viguieri</i> ranges from east coast humid littoral forests on sand and laterite at low elevation to premontane forests along the eastern escarpment at an elevation of up to c. 900 m (Map 9). Material has been collected with flowers in October and November; very young fruits have been recorded in December and mature fruits in late February. <b>Conservation status</b> With an EOO of 28,641 km 2, a minimum AOO of 60 km 2, and 17 localities, with subpopulations in six protected areas (Ambalabe, Analalava, Betampona, Makira, Analamazaotra, and Zahamena), <i>A. viguieri</i> is assigned a preliminary conservation status of “Least Concern’’ [LC] using the IUCN Red List Categories and Criteria (IUCN, 2012). <b>Notes</b> <i>Abrahamia viguieri</i> is easily distinguished from other members of the genus by the lanate upper surface of its leaves and its male flowers with a pubescent disk and completely lacking even a rudimentary or vestigial ovary. PERRIER DE LA BâTHIE (1944) cited two collections in the protologue of <i>Protorhus viguieri</i>, one with male flowers <i>(Humbert &amp; Viguier 815)</i> and the other with fruits <i>(Perrier de la Bâthie 4387</i>, erroneously cited as <i>4397)</i>. We have selected a specimen of <i>Humbert &amp; Viguier 815</i> as the lectotype because it is the best preserved among the syntypes and because an isolectotype was available for distribution to MO. <b>Additional material examined</b> MADAGASCAR.
