Bertya pomaderroides is a species of flowering plant in the family Euphorbiaceae and is endemic to New South Wales. It is a spreading shrub, usually with narrowly elliptic to oblong or narrowly oblong leaves, separate male and female flowers, and oval capsules, sometimes with star-shaped hairs.
Description
Bertya pomaderroides is a spreading shrub with many branches and that typically grows to a height of up to {{cvt|2|m}}. Its young branchlets are covered with whitish or rust-covered hairs at first, but that later become glabrous. The leaves are mostly narrowly elliptic to oblong or narrowly oblong, {{cvt|10–30|mm}} long and {{cvt|3–12|mm}} wide. The upper surface is dark green and glabrous, the lower surface covered with woolly, whitish hairs. Separate male and female flowers are borne on a peduncle up to {{cvt|15|mm}} long, the male flowers with 55 to 55 stamens. Female flowers are sessile or on a pedicel up to {{cvt|1.5|mm}} long, with narrowly triangular sepals {{cvt|2.1–2.7|mm}} long with a more or less glabrous ovary. Flowering occurs throughout the year with a peak in September and October, and the fruit is a narrowly oval capsule {{cvt|6.5–9.8|mm}} long, sometimes with star-shaped hairs, and a single seed.{{cite web |last1=Halford |first1=David A. |editor-last1=Moon |editor-first1=Christina D. |editor-last2=Orchard |editor-first2=Anthony E. |title=Bertya pomaderroides |url=https://profiles.ala.org.au/opus/foa/profile/Bertya%20pomaderroides |publisher=Flora of Australia.
