Scientific name: Amperea xiphoclada var. pedicellata

Amperea xiphoclada var. pedicellata was an erect shrub growing up to 60 cm high. The species possessed rigid, angular branches which were sometimes leafless. When present, leaves were positioned alternately along the branches. Lower leaves were wedge-shaped to oblong, often with toothed margin, and 5–10 mm in length. The upper leaves were linear, scale-like, with entire margins, and were usually less than 10 mm long. The species was usually monoecious (both male and female flowers on one plant). The species had few flowers growing in clusters directly from the stem. The outer whorls of the flower (perianth) were 2–3 mm long. The dry fruits were ovoid in shape and approximately 4 mm long (RBGS 2001).

Amperea xiphoclada var. pedicellata is known only from the type specimen which was collected in 1892 from Double Bay, Sydney, NSW (APNI 2001). This species has not been located since and is presumed extinct.

Amperea xiphoclada var. pedicellata was previously widespread in heath, woodland and forest on low-fertility sandy soils and is now extinct (RBGS 2007). The type locality of this species is presumed to have been somewhat swampy (Henderson 1992c).

The threatening processes that led to the decline and extinction of Amperea xiphoclada var. pedicellata are unknown.

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
