Observations. – Ochna louvelii seems to be a narrow endemic known only from a couple of collections from the humid montane forests around Moramanga on the eastern escarpment. This species differs from O. polycarpa Baker , which occurs in the same region but extends southwards on the highlands to near Fianarantsoa, by its lax inflorescence (vs. contracted in O. polycarpa ) with c. 10-20 minute flowers with sepals> 5 mm (vs. 1-5 larger flowers with sepals 8- 10mm),and from O. thouvenotii by itssmaller leaves (1-2 × 0.8-1.5 cm vs. 3-4.5 cm × 1-2.5 cm) and its many-flowered inflorescences (10-20 vs. 1-5 flowers).
