Description Shrubs to trees to 10 m tall, trunk to 20 cm diameter; young twigs cylindrical, 1-5 mm diameter, glabrous; bark light brown, smooth to slightly rugose. Leaves opposite, persistent; bud scales rarely persistent; blades dark green above, lighter below, oblong, 7-23 3 3-8 cm , chartaceous, glabrous, domatia absent, base acute to rounded, margin slightly undulate, apex acuminate, the acumen 2-19 mm long, midrib slightly sunken above, distinctly raised below, secondary veins conspicuous, 7-16 per side, 11-40 mm apart, looping 3-8 mm from the margin; petiole medium gray, 8-20 3 1.5-3.5 mm , entirely woody, glabrous. Thyrses fasciculate, pauciflorous, diffuse; peduncle 5-23 mm long, densely pubescent; pedicel 7-12 mm long, densely pubescent; calyx densely pubescent on both sides, lobes triangular, 1.5-2 3 1.5-1.8 mm ; corolla purplish, sometimes tinged yellow, subrotate, 4.5-6 mm long, sparsely pubescent outside, glabrous inside, the tube 2-3 mm long, lobes ovate, apex obtuse; corona absent; stamens 2-2.8 mm long, anthers obovate, 1.2-1.5 mm long; pistil 2.5-3 mm long, stigma capitate. Fruiting pedicel 8-28 3 1-3 mm ; young fruits green, purple when mature, subglobose, 13.5-23.5 3 13-24.5 mm , surface smooth, apex apiculate; dry pericarp 0.4-2.2 mm thick; endocarp crustaceous; seed 10.5-20 3 7.5-14 mm . Distribution, ecology and phenology Noronhia grandifolia occurs in low- to high-elevation humid forests from Daraina in the north to Andohahela in the south ( Fig. 19 ). It produces flowers and fruits throughout the year, with a peak between October and February. Conservation status With 23 collections representing 21 localities, the assessment indicated an EOO of 104,491 km 2 , an AOO of 84 km 2 , and 21 subpopulations representing 17 locations, of which 10 occur within protected areas (Andohahela, Anjanaharibe-Sud, Corridor Ambositra-Vondrozo, Loky-Manambato, Makira, Mantadia, Marojejy, Masoala, Ranomafana, and Tsaratanana-Ambohimirahavavy-Corridor Marojejy). Being so widespread and well represented within the network of protected areas, N. grandifolia is assigned a preliminary status of “Least Concern”. Notes Noronhia grandifolia can be recognized by its large, chartaceous leaf blades, pubescent inflorescences, purplish-yellow flowers that lack a corona, and subglobose, crustaceous fruits subtended by long pedicels. 118 Boissiera 70 Additional specimens examined MADAGASCAR .
