"TYPE: Australia, Queensland, Biggenden, P.I. Forster 9318B & P. Machin, 5 Jan 1992 (holo BRI, iso CANB)."


Etymology: Latin, parcus, sparing or frugal, and folius, leaf, from the fine and wispy leaflets.

Historical notes:

Distinguishing features: Closely allied to M. pauli-guilielmi, differing in the even narrower, thinner-textured, darker green leaflets.

Distribution and habitat: An uncommon species occurring in scattered stands on shallow clay-loams derived from basalt in the Biggenden district.

Conservation status: Known only from a few stands, not well conserved and potentially under threat (IUCN Red List category VU; ROTAP category 2V-). Gazetted as a Rare or Threatened Plant under Queensland Nature Conservation legislation. 1997 IUCN Red List of Threatened Plants category V.
