Calytrix nematoclada is a species of flowering plant in the myrtle family Myrtaceae and is endemic to the south-west of Western Australia. It is a shrub with decussate, narrowly elliptic to egg-shaped leaves and purple or deep pink flowers with about 35 to 40 stamens in three rows.
Calytrix nematoclada is a shrub that typically grows to a height of up to and has hairy branchlets. Its leaves are decussate, narrowly elliptic to egg-shaped, long, wide and sessile. There are no stipules at the base of the petiole. The flowers are borne on a funnel-shaped peduncle long with egg-shaped to more or less round lobes long. The floral tube is cone-shaped with the narrower end towards the base, long and has 10 ribs. The sepals are fused at the base, with egg-shaped or elliptic lobes long and wide. The petals are purple or deep pink, elliptic to egg-shaped, long and wide, and there are about 35 to 40 stamens in three rows. Flowering occurs from November to January.[1]
Calytrix nematoclada was first formally described in 1987 by Lyndley Craven in the journal Brunonia.[2] The specific epithet (nematoclada) means 'thread-like branchlets'.[3]
This species of Calytrix grows in heath with Actinostrobus on sand, with Eucalyptus tetragona in low scrub, and with E. incrassata in tall open shrubland in the Bendering-Lake King-Ongerup area in the Esperance Plains and Mallee bioregions of south-western Western Australia.
Calytrix nematoclada is listed as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions meaning that it is poorly known and known from only a few locations but is not under imminent threat.[4]
