Description Shrubs to 3 m tall, trunk to 2.5 cm in diam.; young twigs cylindrical, 0.7-1.3 mm diameter, glabrous; bark medium gray, smooth to slightly rugose. Leaves opposite, persistent; bud scales, rarely persistent; blades medium green above, lighter below, ovate, 5-15 3 1-4 cm , chartaceous, glabrous, domatia absent, base cordate, margin flat to slightly undulate, apex acuminate, the acumen 7-25 mm long, midrib flat to slightly sunken above, flat to raised below, secondary veins conspicuous, 7-12 per side, 7-14 mm apart, looping 1.5-5 mm from the margin; petiole light gray, 3-8 3 0.8-1.9 mm , entirely woody, pubescent. Thyrses geminate to fasciculate, pauciflorous, diffuse; peduncle 3-8 mm long, moderately pubescent; pedicel 8-12 mm long, moderately pubescent; calyx moderately pubescent outside, glabrous inside, lobes ovate, 1.3 3 1.5 mm ; corolla greenish tinged orange to reddish outside, yellowish inside, cupuliform, 6 mm long, glabrous on both sides, the tube 4 mm long, lobes ovate, apex obtuse; corona absent; stamens 3.5 mm long, anthers obovate, 2.5 mm long; pistil 2.5 mm long, stigma capitate to slightly bilobed. Fruiting pedicel 8-13 3 1-2 mm ; young fruits yellowish, beige to purple when mature, globose, 15-23 3 15-23 mm , surface smooth, apex flat, style persistent; dry pericarp 0.2-2.6 mm thick; endocarp crustaceous; seed 12 3 13-15 mm . Distribution, ecology and phenology Noronhia capuronii occurs in low- to mid-elevation dry forests in the north, from Montagne des Français to Ankarana and Daraina ( Fig. 3 ). It produces flowers and fruits from October to June. Conservation status With 14 collections representing 14 localities, the assessment resulted in an EOO of 4,885 km 2 , an AOO of 52 km 2 , and 12 subpopulations representing seven locations, of which five occur within protected areas (Ankarana, Loky-Manambato, Montagne d’Ambre, and Montagne des Français). Noronhia capuronii is assigned a preliminary status of “Vulnerable” [VU B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v)], due to continuing decline in AOO, number of both locations and mature individuals, and in habitat quality resulting from deforestation, charcoal production, and illegal and/or artisanal mining. Notes Noronhia capuronii can be recognized by its chartaceous, cordate leaf blades, pubescent petiole and midvein, thyrsoid inflorescences with green-orangish flowers and subglobose fruits. It differs from N. jeremii Hong-Wa & Callm. and N. richardii Hong-Wa by its ovate (vs. linear to oblong in N. jeremii and lanceolate to oblong in N. richardii ) leaf blades, pubescent (vs. glabrous) inflorescences and greenish tinged orange (vs. yellowish and red, respectively) flowers.
