Amperea xiphoclada pedicellata R.J.F. Hend., 1992
Taxonomy & Nomenclature
Conservation Status
Extinct (Henderson, 1992; Keith et al., 1997:64; Department of the Environment, 2014)
Last record: 1892
"Amperea xiphoclada var. pedicellata is known only from the type specimen, collected in 1892, from the ‘head of Double Bay’ in Sydney, NSW. The variety has not been observed since and is presumed to be extinct (Henderson, 1992). The variety is distinguished by its long (to 13 mm) pedicels (flower stalks). Other A. xiphoclada varieties have pedicels no longer than 0.5 mm (Henderson, 1992).
Nothing is known of the ecology of A. x. var. pedicellosa, but given the collection locality of the type (and only) specimen, it is likely to have occurred in somewhat swampy habitat (Henderson, 1992). The variety is presumed to have become extinct due to the expansion of Sydney. The type locality near Double Bay is now an inner suburb and little, if any, truly remnant vegetation persists there (Walsh, 2014, pers. comm.)." (Department of the Environment, 2014)
