Getting to know your Hawaiian Lobeliads #20: Cyanea arborea


Cyanea arborea

  • Conservation Status: Extinct
  • Distribution: East Maui
  • Date photographed: ?? (J.F. Rock)
  • *Identification: Form– Palm-like trees 4-8 m tall. Leaves– oblanceolate; blades 65-90 cm long by 6-12 cm wide; margins minutely callose-denticulate; sessile. Flower– hypanthium obovoid, 8-12 mm long; calyx lobes dentiform, 0.5-1mm long; corolla cream tinged with pale lilac, 40-50 mm long, 3-5 mm wide.
  • My notes: Here is another of the extinct lobeliads that we have some in-situ photos of. C. arborea was a striking plant from the leeward slopes of Haleakala. Unfortunately this area has seen extensive damage from non-native grazers and browsers. This species was last collected in 1928.
