Based on its large EOO of 36 333 km² and an AOO of 36 km²,  Turraea flagellata sp. nov.is therefore preliminary assessed as “Least Concern” [LC] in accordance with IUCN Red List Categories and Criteria ( IUCN 2012).   ADDITIONAL SPECIMENS EXAMINED. —   Madagascar• Melaky Region[ Prov. Mahajanga], forêt de Tsiampihyet forêts côtières près de Besaraha, de Bemihaet de Soahanina, Nord de Bemika; [ 18°44’S, 44°20’E]; 0-20 m;  30.XII.1952; fl.; Leandri et al. 2277( G[ G00642050], K, MO, P[ P06709116, P06709127, P06709128], TAN) • env. de Mahajanga; [ 15°43’S, 46°19’E];  XII.1903; fl.;  Perrier de la Bâthie1663( P[ P06709126, P06709130]) • Bemaraha, Antsalova; [ 18°41’S, 44°46’E];  11.I.1959; fl.; Réserves Naturelles 10206( P[ P06709121, P06709132]) •  ibid. loco;  13.I.1959; fl.; Réserves Naturelles 10209( P[ P06709120, P06709133]) • Tsimembo,   FIG. 2. —  Turraea flagellataJ.-F.

Leaves unifoliolate; leaf blades chartaceous to subcoriaceous, elliptic, glabrous, (2-)2.5-3(-6) × (1-)1.5-2(-2.5) cm, base acute, margin entire, sometimes undulate, apex acuminate, adaxial surface shiny dark green, abaxial surface light green, dull, domatia absent; primary vein slightly prominent, secondary veins finely prominent on both surfaces; reticulum distinct; petiole 2-3 mm, long, puberulent. Inflorescence pauciflorous, 1-5 flowers. Flower buds yellowish, enlarged and acute-obtuse at the apex. Flowers 2-3 cmlong; pedicel 10-12 mmlong, puberulent. Calyx grey-green, cupuliform, 3 × 2 mm, 5-lobed, each lobe with a linear tooth 1 × 0.2 mm, finely pubescent on the outside, glabrous on the inside. Corolla white of 5 linear-spatulate petals, longer than the staminal tube, 20-25 mmlong, 1 mmwide at base, 1.5 mmwide in the proximal part. Staminal tube cylindrical, 3.5 mmlong, 0.8 mmin diam., glabrous outside, densely tomentose inside; rudimentary appendages at the base of each anther, glabrous. Anthers 10, subsessile, oblong, 1.8 × 0.2 mm, with a filiform apicle, tapering and twisted distally, up to 15 mmlong, glabrous. Ovary subglobose, 0.8 mmin diam, glabrous, locules 5, each with 2 collateral ovules; style exserted 3-4 mmbeyond the staminal tube, 0.2 mmin diam. Receptaculum pollinis oblong, 3 × 1.5 mm; stigma capitate, 0.8 × 0.3 mm. Fruits unknown.  NOTES This new species is very distinctive among the Malagasy  Turraeaspeciesby its anthers bearing a long and filiform apicle ( Figs 2; 3A). We attribute this name to Leroy & Lescot. Only two collections have been gathered since their unpublished description. Furthermore, the typecollection, Leandri 291, and several others have been already distributed under that name by Sabine Comtet-Andriamanjatoarivo (1961-2013), back then technician of the P herbarium, when she was curating the Malagasy  Meliaceaeleft by Michèle Lescot after her retirement. 4906767320 1932-10-15 P, G, K, MO, NY, TAN, TEF, WAG Madagascar Melaky Region 38 -18.583334 Soahany 1275 44.233334 Tsiampihy 4 105 P00263853, G00415946, P00263852, P00263854 3 Mahajanga holotype 4906767302 [1168,1404,1798,1822] 1932-10-15 P, G, K, MO, NY, TAN, TEF, WAG Madagascar Melaky Region 38 -18.583334 Soahany 1275 44.233334 Tsiampihy 4 105 P00263853, G00415946, P00263852, P00263854 3 Mahajanga holotype 4906767317 1932-10-15 P, G, K, MO, NY, TAN, TEF, WAG Madagascar Melaky Region 38 -18.583334 Soahany 1275 44.233334 Tsiampihy 4 105 P00263853, G00415946, P00263852, P00263854 3 Mahajanga holotype 4906767400 1903-12 1959-01-13 1903-12 G, K, MO, P, TAN Madagascar 10 6 107 -18.683332 Nord de Bemika 1274 44.766666 Melaky Region 5 106 G00642050, P06709116, P06709127, P06709128, P06709126, P06709130, P06709121, P06709132, P06709120, P06709133 1 Mahajanga 4906767325 1903-12 1959-01-13 1903-12 G, K, MO, P, TAN Madagascar 10 -18.683332 Nord de Bemika 1274 44.766666 Melaky Region 6 107 G00642050, P06709116, P06709127, P06709128, P06709126, P06709130, P06709121, P06709132, P06709120, P06709133 1 Mahajanga 4906767389 1903-12 1959-01-13 1903-12 G, K, MO, P, TAN Madagascar 10 -18.683332 Nord de Bemika 1274 44.766666 Melaky Region 6 107 G00642050, P06709116, P06709127, P06709128, P06709126, P06709130, P06709121, P06709132, P06709120, P06709133 1 Mahajanga 4906767401 1903-12 1959-01-13 1903-12 G, K, MO, P, TAN Madagascar 10 -18.683332 Nord de Bemika 1274 44.766666 Melaky Region 6 107 G00642050, P06709116, P06709127, P06709128, P06709126, P06709130, P06709121, P06709132, P06709120, P06709133 1 Mahajanga 4906767367 [665,772,2003,2027] 1903-12 1959-01-13 1903-12 G, K, MO, P, TAN Madagascar 10 -18.683332 Nord de Bemika 1274 44.766666 Melaky Region 6 107 G00642050, P06709116, P06709127, P06709128, P06709126, P06709130, P06709121, P06709132, P06709120, P06709133 1 Mahajanga 4906767349 P Service Forestier 75 -18.933332 Antsalova 1273 44.45 6 107 P06709124, P06709131 1 4906767331 1956-02-23 P Service Forestier Foret d'Amboloando 70 -18.016666 Distr.
