13. Trichoscypha olodiana Breteler , sp. nov.

Trichoscyphae bijugae Engl. affinis floribus masculinis circum sessilibus et disco glabra sed differt foliis simplicibus sub inflorescentia et antheris multo minoribus.

TYPUS. — Hall & AbbiwGC45542, Côte d’Ivoire ,

Olodia, Ƌ fl. Aug. (holo-, K).

Tree 4 m tall. Branchlets densely velutinous. Leaves 9-jugate or simple (see note), the petiole, rachis, petiolules and midrib of leaflets beneath woolly-velutinous, the same indumentum present on the impressed midrib above and the main laterals beneath, and to a lesser extent on remaining lower surface. Leaflets and simple leaves ± papery, elliptic to lanceolate (8-)13-30 × (3-) 4- 8 cm, up to 4 times as long as wide, with 11- 14(-20) pairs of main lateral nerves, rounded to obtuse at base, shortly acuminate, the acumen 0.5-1 cm long acute at apex. Inflorescence terminating a long shoot with some simple leaves below, woolly-velutinous. Male flower: sessile or nearly so; calyx subappressed-hairy to almost glabrous, 0.5-1 mm long, the subtriangular lobes minute, ≤ 0.2 mm long; petals ovateelliptic, 1-1.5 mm long, glabrous or with a few hairs outside or on both sides; stamens ± as long as petals, glabrous, anthers ≤ 0.3 mm long; disc ± flat to ruminate, or concave, glabrous or with a very few hairs. Female flower and fruit unknown. — Figs. 8 , 9.

HABITAT AND DISTRIBUTION. — Rain forest of Liberia and western Côte d’Ivoire.

SPECIMENS EXAMINED. — CÔTE D’ IVOIRE: Hall & Abbiw GC45542 , Olodia, Ƌ fl. Aug. ( K), type . — LIBERIA: Voorhoeve 1215, Bomi Hills, Ƌ fl. Aug. ( WAG) .

NOTE. — The leaves below the inflorescence are described as simple, not as unifoliolate, which might be expected in a family with compound leaves. They look simple and I have not found any indication that ‘unifoliolate’ would be a better characterization. Moreover, simple leaves do occur in Anacardiaceae , for instance in Anacardium , Fegimanra , Heeria and Mangifera .
