  • Description & Ethnobotany
    • Plant Morphology :
      [Others]: Large tree with rounded, weeping crown. Evergreen in equatorial climates, but deciduous in areas with seasonal rainfall. Popular ornamental and shade tree in Southeast Asia. National tree of Philippines, where it is known as Narra. Widely used as 'instant tree' in Singapore during 1960s due to fast growth and ability to root from large branch-cuttings. Severely affected by fungal epidemic (Fusarium Wilt) during 1980s in Singapore. Susceptible to being attacked and defoliated by moth leaf-miners in recent years. Branches pendulous, quite weak, prone to being broken during storms.Flowers yellow, faintly fragrant, source of honey for bee pollinators. Periodic mass-blooming triggered by unknown factors, flowers last for a day. Fruits are disc-like pods with papery wings, non-dehisicent (unlike typcial legumes), take up to 6 months to mature, dispersed mainly by wind. Genus name 'Pterocarpus' is derived from ‘pteron’ and ‘karpos’, meaning ‘winged fruit’.
