Platysace compressa, commonly known as tapeworm plant,[2] is endemic to the south-west of Western Australia. It is an erect, ascending or low-lying perennial herb, sometimes with no leaves, or leaves reduced to scales, on flat, winged stems.

Description[edit]

Platysace compressa is an erect, ascending or low-lying perennial herb that typically grows to a height of 0.15–1.2 m (5.9 in – 3 ft 11.2 in). Its stems are flat and rigid, striated and winged, sometimes 4–6.5 mm (0.16–0.26 in) wide. The leaves are small and scale-like, or absent. White or cream-coloured flowers are borne on the ends of branches in compound umbels with thin spreading rays, some of the longer rays with umbellules, sometimes also compound.[3] Flowering occurs from September to March or from January to March.

Taxonomy[edit]

This species was first formally described in 1805 by Jacques Labillardière who gave it the name Azorella compressa in the his Novae Hollandiae Plantarum Specimen.[4][5] In 1939, Cecil Norman transferred the species to the genus Platysace as P. compressa in the Journal of Botany, British and Foreign.[6] The specific epithet (compressa) refers to the flattened stems of this plant.[7]

Distribution and habitat[edit]

Platysace compressa grows on coastal limestone and sand dunes, sometimes on granite hills and outcrops in the Esperance Plains, Jarrah Forest, Mallee, Swan Coastal Plain and Warren bioregions of south-western Western Australia.[2]
