Linospadix microcaryus var. multisecta Beccari Bacularia sessilifolia var. multisecta Beccari Bacularia microcarya


Australia. North-east Queensland. From Mts. Spurgeon and Lewis to just south of Innisfail, most common on the lower slopes of Mts. Bartle Frere and Bellenden-Ker, and the Malbon Thompson Range, from 0-1600 m elevation, in rainforest on granite, or occasionally on basalt and metamorphics.

Derivation of Name:

Latin, micro - small, carya - fruit, in reference to the comparalively small fruit of this species.


Clustering, small palm. Stems 1-6, to 3 m tall, 7-25 mm diameter, internodes elongate, green; crown with 5-9 leaves. Leaves 28-70 cm long, irregularly segmented with united pinnae, segments broadly adnate to the rachis, or regularly pinnate; petiole 1-23 cm long, 3-6 mm wide; pinnae 3-23 per leaf, 11-36.5 cm long, by 0.9-7.4 cm wide, I when backlit under 10x magni~cation, has numerous scattered clear elongate 'cells' 0.5-1 mm long linearly parallel to midrib and veins. Inflorescence to 80 cm long. Staminate flowers globose to bullet-shaped in bud, 2-5 mm long; petals 3 times the length of sepals, apically rounded, without longitudinal striations, cream/dull yellow at anthesis, not widely opening; stamens 8-12; connective not extending beyond the anther. Fruit globose/turbinate, 5-9 mm long by 5-8 mm wide, yellow-orange, or pink to red at maturity; epicarp smooth. Seed subglobose.

This species is the most common Linospadix in the Mt. Bellenden-Ker and Mt. Bartle Frere area. Linospadix microcarya stands apart from the other species due to some unique features: the leaf lamina contains elongate clear 'cells' that are visible under 10x magnification, fruit is globose/turbinate, and staminate flowers are globose and do not open widely at anthesis.

Linospadix microcarya - as Bacularia microcarya - was described by K. Domin in 1915 from a collection made by E M. Bailey from Harvey' s Creek in the foothills of Mt. Bartle Frere, Queensland.
