"TYPE: Australia, Queensland, c. 26.5 km south of Bundaberg beside the road to Goodwood, D.L. Jones 6341 & B.E. Jones, 29 September 1990 (holo CANB, iso CANB, BRI, NSW)."


Etymology: From the genus Lomandra and the Latin termination -oides, resembling, from the perceived resemblance of a plant of this species to a clump of the Australian monocot genus Lomandra.

Historical notes:

Distinguishing features: Most similar to M. platyrhachis, distinguished by the narrower and more erect rachis, and narrower leaflets.

Distribution and habitat: Central-eastern Queensland, a relatively restricted area south of Bundaberg and east of Childers. Usually in dense colonies in sclerophyll forests on sandy soils.

Conservation status: Known only from a few stands, not well conserved and under significant threat from habitat destruction. (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 E.
