Peltophorum dasyrhachis (Miq.) Kurz var. dasyrhachis

Distribution and ecology in Madagascar. – Peltophorum dasyrhachis var. dasyrhachis occurs in the DIANA Region of Antsiranana Province and has been found growing in two habitats: on a sandy beach near sea level along the edge of degraded gallery forest on Nosy Be, and in secondary riparian forest among rocks and boulders at ca. 40 m elevation in the Sambirano Basin. One 20 m tall tree with flowers and old fruits was seen at the Nosy Be locality. A male long-billed green sunbird ( Nectarinia notata Müller, 1776 ) was observed visiting the fragrant yellow flowers around 10 am ( Fig. 1 ). The tree from Sambirano was smaller (ca. 4 m tall) and the abundance at this site was not recorded on the herbarium label. Additional photographs of Rogers & al. 1177 taken in the field are available on TROPICOS (2012).
