Bingabing thicket in Hilo, HI

Identification: This distinctive small tree has columnar stems and huge umbrella like leaves. It can grow from 5 - 10 m (15 - 30 ft) tall with round leaves 60 - 100 mm (1 - 4 in) long. Stem attached to the middle of the leaf, rather than the edge. Pink, petal-less flowers form in clusters near the base of the leaf stalk. Young plants may superficially resemble Hawaiian taro (Colocasia esculenta.)
Impacts: On the island of Hawai‘i, bingabing was seeded from airplanes along with many other weedy forestry species near Hilo after a fire. Today, it lines roadsides, gulches, and disturbed forests in the vicinity. Its large leaf structure creates a dense growth that can crowd and shade out other vegetation.
Dispersal Mechanism: Long distance dispersal of bingabing is achieved primarily through humans who use the plant in ornamental landscaping or reforestation. Bingabing is an established pest on the islands of Oahu and Hawaii, but has been removed from Maui by the Maui Invasive Species Committee (MISC) and is not known to currently grow in Maui County, (see map.)

Characteristics:
profuse reproduction easily spread by wind, water, animals adapted to diverse habitats large food reserves profuse growth More information about this pest external link


Bingabing look-alikes:


Parasol leaf tree (Macaranga tanarius):
This relative of bingabing is another invasive pest that has already escaped into the wild on West Maui and may prove to be a pest in the rest of Maui County. It can be distinguished from bingabing by its smaller leaves (60-100 cm or 24-40 in) and pale green to yellowish green calyx (tough outer petals that protect the bud before it opens).

THIS LOOK-ALIKE IS ALSO A PEST!
