Brachyscome gracilis subsp. robusta P.S.Short

J. Adelaide Bot. Gard. 28: 54 (2014) APNI

Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Native

Threat status:Victoria: endangered (e)

Basal leaves (1.2–)3–6(–9) cm long, (0.25–)0.5–1.2(–1.8) cm wide, with 3–8(–12) lobes. Cypselas 1.3–2.2 mm long, red­-brown or black when mature. Flowers Sep.–Nov.

RobP. Known only in a Eucalyptus largiflorens floodplain on clay soil at Kings Billabong, near Red Cliffs in north-western Victoria.

The rank of subspecies rather than species has been assigned to this taxon due to its close morphological similarity to the nominate subspecies. In addition to subtle morphological differences its formal recognition is warranted based on its hexaploid ploidy (2n=24 based on x=4) in contrast to the diploid ploidy (2n=8) that has been observed in several specimens of the nominate subspecies (Watanabe & Short 1992) and on its floodplain habitat (Short 2014).
