Endemic to the Perth region of WA - no more than about 100km from the CBD, in fact.

Described by Scottish physician and botanist Robert Graham (1786-1845) in 1841, although his first encounter with the species wasn't in Australia -

'I first saw this species in the nursery of Mr. CUNNINGHAM, Comely Bank, near Edinburgh, where it flowered in a frame in May, 1840. In the month following, we received it at the Botanic Garden, Edinburgh, from Mr. HENDERSON'S nursery in the Edgeware-road, and at the same time from Mr. JACKSON, Nurseryman, Kingston, Surrey. It is indigenous to the neighbourhood of Swan River, [Western] Australia.'

Looks like we were a week or so too early to see the flowers, last September. Despite the name, the flowers are mostly white - see this photo by Robert Davis -

Widespread along the Darling Escarpment and in adjacent regions.

The specific epithet refers to the leaves, which resemble those of the sedge genus Schoenus.

Yet another WA endemic, growing in sand, sandy loam, and granite, on hillslopes, dunes, and plains, in forests, heaths, woodland and shrublands. it has a particularly vigorous trigger mechanism.

One of many Stylidiums spotted over the duration of the BioBlitz.

Widespread on hilltops, plains, forests, open woodlands, and low heath of the SW, in clayey sand or loam over laterite.
