GoogleMaps   .

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.

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.

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.

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.
