Description
editLaccospadix australasicus may be solitary or clustering, in the former the trunks will grow to around 10 cm in width while clustering plants are closer to 5 cm wide. The trunks may be dark green to almost black at the base, lightening with age, and conspicuously ringed by leaf scars. Lone trunks will reach 7 m in height while the suckering varieties grow to 3.5 m. The leaves are pinnate, emerging erect with a slight arch, to 2 m on 1 m or less petioles; the petioles and rachises are usually covered in scales. The new foliage is often red to bronze, a feature more common in solitary individuals.[3]
The inflorescence is a long, unbranched spike, emerging within the leaf crown, to a meter long, carrying male and female flowers, both with three sepals and three longer petals. Laccospadix fruit is slightly ovoid, one-seeded and bright red, with a smooth epicarp and a thin fleshy mesocarp.[4]
Distribution and habitat
editFound in Queensland, Australia at elevations of 800–1400 m in humid rain forest, they grow on mountains and plateau where they receive little light.
