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 near sea level to 1600 m elevation, in rain forest on granite, or occasionally on basalt and metamorphics. (J.L.

Discussion

  • Bailey's 1889 collection from Harvey's Creek (BRI [AQ75431]), cited by Domin in his 1915 protologue, is the type specimen for Linospadix microcarya. 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 turbinate (infrequently globose), and staminate flowers do not open widely at anthesis.

Description

  • Clustering small palm. Stems l-6, to 3 m tall, 7-25 mm diam., internodes elongate, green; crown with 5-9 leaves. Leaves 28-70 cm long, irregularly segmented with united pinnae, segments with broad bases, 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, semiglossy, lettuce to mid-green above, sometimes dark green when in deep shade, lighter green below; midrib and secondary veins prominent on both surfaces; terminal pair broader than adjacent laterals and often basal pair broader than laterals; lamina, when backlit under 10X magnification, with numerous scattered clear elongate "cells" 0.5-1 mm long linearly parallel to midrib and veins. Inflorescence to B0 cm long. Staminate flowers globose to squatly bullet-shapedi n bud, 2-5 mm long; petals three 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 to turbinate, 5-9 X 5-a mm, yellow-orange, or pink to red at maturity; epicarp smooth. Seed subglobos. (J.L.
