It has been collected in flowers in November and December.   Conservation status Only three collections, representing three localities, were available and were all obtained from a single location within the recently established protected area of Tsitongambarika. The subpopulation occurs on the northeastern edge of the protected area, where significant human activities still put some pressure on the forest, resulting in continuing decline in habitat quality. Thus, with an AOO of just 8 km 2, a single location, and lingering threats that could rapidly affect the area,  N. richardiiis assigned a preliminary status of “Vulnerable” [VU D2].   Notes   Noronhia richardiiclosely resembles  N. capuronii, from which it differs by its glabrous (vs. pubescent) petioles, lanceolate to oblong (vs. ovate) leaf blades with an acute to rounded (vs. cordate) base, long peduncles and pedicels (up to 30 mmvs. 8 mm), and red (vs. greenish) flowers. It can be recognized by its lanceolate leaves and long, diffuse inflorescences with red flowers.    Paratypi   MADAGASCAR. Prov.
