Appearance

The scrub breadfruit is an evergreen shrub or small tree usually growing to between 3 and 6 m high, and rarely to 10 m. It produces multiple stems which are weak and become decumbent with age, i.e. they lean to one side and eventually lie on the ground with just the growing tip erect. The stems measure around 5 cm in diameter, and prop roots are absent.

The leaves are tightly clustered on the growing tip of the stem and are arranged spirally. They are very long and narrow, measuring up to 2.5 m long by 5 cm wide, and are ascendant to arching. They are dark green above and a lighter green below, and are pleated such that they have an M-shaped cross-section. Small spines are present on the leaf margins and the underside of the midrib.

This species is dioecious, meaning that functionally female and functionally male flowers are borne on separate plants. The inflorescence is a terminal spike, enclosed by large creamy-white bracts.

The fruit is a multiple fruit, in other words it is a single body consisting of the merged maturing ovaries of a cluster of flowers. It is orange-red to bright red, roughly spherical to slightly egg-shaped, and measures up to 12 by 12 cm Each fruit contains over 300 segments around 3 cm long by 0.4 cm wide, each tipped by a persistent style.

Naming

The species epithet "monticola" is derived from the Latin words "mons" and "-cola", meaning "mountain dweller".

The common name "scrub breadfruit" is a reference to the superficial similarity of the fruit to the more well-known breadfruit.

Distribution

The scrub breadfruit naturally occurs from the area of Cedar Bay, southward along the coast as far as Hinchinbrook Island, and inland to the Atherton Tablelands. It favours rainforest habitats and is found from sea level to around 800 m.

The fruits are eaten by cassowaries and giant white-tailed rats.
