Habitat

Discussion

  • Livistona fulva was described by Rodd (1998) based on Rodd 3062 from Blackdown Tableland, and named for the coppery brown floccose tomentum on the abaxial surface of the leaf. The relationships of L. fulva are unclear, but it is most similar to L. muelleri in having a flat rigid lamina, to L. decora in inflorescence size and morphology, and to L. victoriae in overall size and fruit morphology. Livistona fulva is a moderate sub-canopy palm to 13 m tall; leaves are moderate and regularly segmented, and with coppery brown floccose tomentum abaxially; segment apices are rigid, and with a bifurcate cleft to only 5% of the segment length; the inflorescence is unbranched, not extending beyond the limit of the crown, and with up to 9 partial inflorescences; bracts are loosely sheathing; flowers are yellow; fruit are globose to 16 mm diam., and pruinose dull black at maturity.

Description

  • Functionally dioecious palm. Trunk to 13 m tall, 20-25 cm dbh, leaf scars raised, internodes narrow, grey or brown, petiole stubs deciduous. Leaves 25-35 in a globose crown; petiole 150-250 cm long, 12-15 mm wide, adaxially moderately ridged, basal margins armed with single, curved black spines; leaf-base fibres moderately prominent, fine, persistent; lamina costapalmate, regularly segmented, circular in outline, 90-100 cm long, coriaceous, adaxially greyish green to glaucous, coppery brown floccose tomentum abaxially; lamina divided for 50-55% of its length, with 60-66 segments, depth of apical cleft 3-5% of the segment length, apical lobes acute to acuminate, rigid; parallel veins 8-9 each side of midrib; transverse veins thinner than parallel veins. Inflorescences unbranched at the base, not exually dimorphic, 100-230 cm long, not extending beyond the limit of the crown, branched to 4 orders; partial inflorescences 7-9; peduncular bract 1, loosely sheathing, with orange-brown scales; rachis bracts loosely sheathing, with orange-brown scales; rachillae 5-16 cm long, papillose. Flowers solitary or in clusters of 2-3, funnel-shaped, yellow, 1.6-2 mm long; sepals narrowly triangular, 1.0-1.3 mm long, membranous, acute; petals broadly ovate, 1.6-2 mm long, thick, acute; stamens ca. 1.6 mm long. Fruit globose, 12-16 mm diam., pruinose dull black; epicarp smooth; suture line not obvious; mesocarp thin, fibrous; endocarp thin, crustaceous. Seed globose, 10-13 mm wide. Eophyll 5-ribbed.
