Synonymy:
Bacularia palmerianaDistribution:
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".Description:
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.
Figure 1. L. palmerianaLinospadix palmeriana is the most consistantly 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.
