TAXONOMIC REVISION OF LEANDRA SECT. LEANDRA
Phytotaxa 262 (1) © 2016 Magnolia Press • 37 Shrubs, 2 m tall. Branches, petioles, leaves, inflorescences, bracts and bracteoles covered by unbranched trichomes (1–3(4) mm), these very sparse on the old branches and leaf surfaces, and denser on petioles and hypanthia. Leaves slightly anisophyllous in each pair (8:10 ratio); petioles 0.6–1 cm long; blades 6–11 × 2–3 cm, lanceolate, apex acuminate to caudate, base obtuse, margin entire, ciliate (2 mm), subchartaceous; 3 acrodromous nerves, plus 1 additional pair of faint veins, basally nerved, acrodromous nerves slightly conspicuous on adaxial surface and acrodromous and transversal nerves slightly prominent on abaxial, reticulation slightly conspicuous. Inflorescences axillary, 2 per node, 1 cm long, opposite paraclades absent, accessory branches absent, 3 flowers per inflorescence, these in glomerules; bracteoles 7–9 × 2–3 mm, oblong, uniformly covered by unbranched trichomes, involucral, persistent. Flowers 6-merous, sessile. Hypanthium 4.5 × 2.5 mm, tubular, torus indumentum absent. Calyx tube 0.3 mm long; inner lobes 0.9–1.1 × ca. 0.5 mm, lanceolate; external teeth 3.5 mm long. Petals white, 4.8–5.2 × ca. 0.7 mm, linear, apex acuminate, glabrous, spreading at anthesis. Stamens 12, opposite to the style; filaments geniculation present, the larger 5 mm long, the smaller 4.5 mm long; anthers pink, the larger 3.7 mm long, the smaller 3 mm long, linear-subulate, straight, pore ca. 0.15 mm wide, connectives dorsally not produced below the anthers, appendage absent. Ovary 4-celled, 2.5 × 1.2 mm, 40–50 % inferior, apex sparsely covered by unbranched trichomes (0.5 mm). Style 10 mm long, sigmoid, opposite of the stamens, stigma 0.25 mm diam. Fruits and seeds not seen.
Notes:—Among the morphologically similar species, Leandra capitata can be differentiated from L. angustifolia by the longer trichomes and bracteoles, and from L. cogniauxii by the lanceolate leaves. There are few collections of this species and it does not seem to be sympatric with any morphologically close relative with which it might be confused. A new name for this species is proposed, since the epithet consimilis is already taken in Leandra . The epithet used by the author of the first name proposed for this taxa was chosen to designate the new name. Ossaea capitata Vinha was a posterior homonym of Ossaea capitata Urb.
