Scientific name: Platyzoma microphyllum
Conservation status in NSW: Endangered
Commonwealth status: Not listed
Profile last updated: 21 Nov 2018

Description

Clumped fern covered with copper-coloured hairs. Fronds crowded, both simple in shape and divided, simple fronds linear, green, 3-7 cm long, inconspicuous and often easily overlooked, the divided or pinnate fronds with numerous pouch-like segments on each side of the stem, usually 20-35 cm long. Reproducing by spores contained within black fruiting bodies (sori) borne on the under surface of the fronds along the veins.

Distribution

Recorded in NSW only in the Yetman district. The species is widespread across northern Australia, from WA to the NT, eastern Qld and just into central-northern NSW.

Habitat and ecology

  • Grows in sandy or swampy soils, or in clay soils adjacent to streams and lagoons and subject to periodic flooding.
  • Recorded in NSW at Bruxner Highway growing as one localised patch in deep sandy soil, with Leptospermum species, Brachyloma daphnoides and Lomandra species.
  • The fern was growing at Bebo State Forest in Angophora and Callitris woodland in sandy soil, and a very open sunny position also in sandy soil.
  • Other associated species include Hakea dactyloides, Brachyloma daphnoides, Jacksonia scoparia, Xylomelum cunninghamii and Calytrix tetragona.
  • Grows in Qld in deep sandy soils over clay where there is periodic marked increase in the level of the water table, or sometimes in clay beside streams or lagoons where the ground is subject to periodic, prolonged inundation by water.
  • Fertile plants of Platyzoma microphyllum have been recorded throughout most of the year.
  • Populations can form tussocks or colonies up to several metres across; in NSW the fern forms very localised and clumped populations.
