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.

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.

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”.

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.
