Pimelea cremnophila

Pimelea cremnophila is an erect shrub that typically grows to a height of up to and has reddish-brown stems, covered with bristly hairs when young. Its leaves are narrowly elliptic to narrowly egg-shaped, long and wide on a densely hairy petiole about long. The flowers are borne on the ends of branches or in leaf axils, singly or in groups of up to four on a peduncle about long. There are leaf like bracts long at the base of the flowers but that fall off as the flowers develop. Some flowers are functionally male, others functionally female and the remainder bisexual. Bisexual flowers have a floral tube long and sepals long, male flowers a longer floral tube, and female flowers a shorter floral tube and smaller sepals. Flowering has been observed in October, but is likely to occur throughout spring. ==Taxonomy==

Pimelea cremnophila was first formally described in 2006 by Lachlan Copeland and Ian Telford from specimens collected in the Oxley Wild Rivers National Park in 2004. The specific epithet (cremnophila) means "cliff-loving". ==Distribution and habitat==

Gorge rice-flower grows on exposed cliff-tops and sheltered cliff-sides at altitudes between in the southern part of the Oxley Wild Rivers National Park. ==Conservation status==

At the time of writing their paper, Copeland and Telford reported that P. cremniphila was "known from fewer than 100 individuals". In 2015, a visit by Copeland to the area failed to find two of the three populations. The main threats to the species are grazing by feral goats, drought and inappropriate fire regimes. The species is listed as "critically endangered" under the New South Wales Government Biodiversity Conservation Act 2016. ==References==
