AVH map***

Distinctive in its habit, with long thin scape and short brush-like spike, large cream to yellow flowers with inner tepals much larger than other species, long-pointed fruit with persistent styles and rounded glossy seed. Leaves longer (1–2 m) than in most species, with stomates in subsurface hair-lined chambers rather than singly as all other N.S.W. species.
