Distribution and ecology

Found near Charleville and Cunumulla in SW Qld and near Bourke in NW NSW.


Part of the S. esuriale group of subgen. Leptostemonum (Bean 2004).

Previously treated as part of S. coactiliferum by Symon (1981) and most closely related to this widespread species. Symon was probably referring to this species when he referred to a "rather narrow-leafed form from south western Qld which may also occur occasionally in N.T."

The two species differ by


According to Bean (2004) the white glandular papillae on the ovary and style persist in fruit, giving them a sticky feel. This characteristic is unknown in other Qld species, but its occurrence outside Qld has still to be documented.


Derivation of epithet

From the Greek ammo-, of the sand, and -philus, loving,  a reference to the preferred sandier soils of this species.
