Darwinia collina, commonly known as the yellow mountain bell, is a plant in the myrtle family Myrtaceae. It grows as an erect shrub 0.3–1.2 metres (1–4 ft) high with crowded elliptical leaves[2] and bright yellow flower-like inflorescences. It is endemic to a few small areas in the Stirling Range National Park, Western Australia and as a result is classified as an endangered species.[3]

Description

The yellow mountain bell is a small, compact, erect shrub up to about 1.2 metres (4 ft) high. Its leaves are about 10 millimetres (0.4 in) long, 5 millimetres (0.2 in) wide and minutely toothed. Bell-shaped, flower-like

styles are up to 20 millimetres (0.8 in) long and sometimes protrude slightly beyond the bracts.[5] Both the leaves and bracts of Darwinia collina are more rounded than those of any other Darwinia species. The bell shape of the inflorescence is likely to protect the flowers from rain.[6]

Taxonomy

Darwinia collina was first formally described in 1923 by

C.A.Gardner from a specimen collected on Bluff Knoll by "Mrs Pelloe" and the description was published in Journal and Proceedings of the Royal Society of Western Australia.[7][8] The specific epithet (collina) is a Latin word meaning "on a hill".[9] Darwinia collina is known to hybridise with Darwinia leiostyla.[4]

Distribution and habitat

The only known locations where Darwinia collina is found are

Phytopthera cinnamomi.[4]

This darwinia grows in dense heath and thicket in shallow, siliceous soils over sandstone and shale on mountain summits. The area in which the populations occur are in the Eastern Stirling Range Montane Heath and Thicket Threatened Ecological Community which only occur at altitudes between 750 and 1090 metres.[11][12]

Conservation status

Yellow mountain bell is classified as "

Setonix brachyurus) and damage caused by recreational activities.[4]

Cultivation

As with others in the genus, D. collina is difficult to grow from seed. It can be grown from cuttings and as a potted plant but is difficult to maintain in the garden.[2] Some success has been reported with grafts onto D. citriodora.[13]
