Getting to know your Hawaiian Lobeliads #6: Cyanea angustifolia

Cyanea angustifolia

  • Hawaiian Name: Haha
  • Conservation Status: Apparently Secure
  • Distribution: O’ahu, Moloka’i, Lana’i, Maui
  • Date photographed: 8/9/2010
  • Ease of viewing: Easy
  • *Identification: Form– Branched shrub 1.5-5 m tall. Leaves-lanceolate, narrowly elliptic, or narrowly oblong; blades 9-32 cm long by 1.5-5.5 cm wide; margins callose-crenulate to callose-crenate; petioles 2.5-9 cm long. Flower– hypanthium purple, obovoid, 3-6 mm long; calyx lobes dentiform, 0.5-1 mm long; corolla white or greenish white, 20-30 mm long.
  • Phylogenetic comments: C. angustifolia is part of the clade of Cyanea that has purple fruit. Many of these purple-fruited types can be found in more open forest habitat, as opposed to the forest interiors like the orange-fruited Cyanea2022 update — C. angustifolia seems to have diverged early on from C. pyrularia and together with C. membrenacea  and species related to C. mannii form the angustifolia clade.
  • My notes: Currently, this is the second-most common lobeliad found in the Manoa Cliff restoration site. It is quite easily seen along the trail. Some of the older ones are about 10-12 ft tall. Another very easy to see individual is off the popular Aiea Loop trail.
