Bacularia palmeriana


Australia. North-east Queensland. Confined to Mts. Bartle Frere and Bellenden-Ker, in rainforest, on granite, metamorphics and occasionally on shallow basalts overlying metamorphics, from 300 - 1600m elevation.

Derivation of Name:

Named for Edward Palmer, M. L. A., of whom Bailey wrote "indebted for much useful information as to the uses made by the aboriginals of our indigenous plants".


Clustering, small palm. Stems 1-6, to 3 m tall, 5-20 nun diameter; internodes elongate, green; crown with 8-12 leaves. Leaves regularly segmented with united pinnae, most often with two segments either side of rachis, infrequently simply bi~d, segments broadly adnate to the rachis, or regularly and finely pinnate; petiole 5. 5 - 13 cm long; pinnae 2-24 per leaf, dull to semi-glossy dark green above, lighter green below; midrib prominent on both surfaces, veins numerous and prominent on both surfaces, terminal pinnae broader than laterals; lamina, when backlit under 10x magnification, has numerous circular clear 'cells' to 0.1mm wide linearly parallel to midrib and veins. Inflorescence to 60cm long. Staminate flowers bullet-shaped in bud, glabrous, to 3mm long by 2mm wide; petals apically rounded, green at anthesis, not widely opening, deeply striate in the dried state; stamens 6-9; connective not extending beyond the anthers; anthers oblong. Fruit elongate/cylindrical, 10-15mm long by 5-7 mm wide, yellow or red at maturity; epicarp smooth or moderately rugose. Seed elongate/ellipsoid.

Linospadix palmeriana is the most consistently diminutive species in the genus. Plants are most often less than 1 m tall, with stems less than 10 mm diameter. Leaf lamina is rigid with ribs raised on both sides. Linospadix palmeriana - as Bacularia palmeriana - was described by F. M. Bailey from a collection taken at 700 m altitude on Mt. Bellenden-Ker, Queensland.
