'''''Guichenotia micrantha''''', commonly known as '''small flowered guichenotia''',<ref name=FB>{{FloraBase|name=''Guichenotia micrantha'' |id= 5013}}</ref> is a species of flowering plant in the family Malvaceae and is endemic to the south-west of Western Australia. It is a low, compact shrub with linear to narrowly egg-shaped leaves and pink flowers in groups of three to six.
==Description== ''Guichenotia micrantha'' is a compact shrub that typically grows to {{cvt|0.3–1.5|m}} high and wide, its new growth densely covered with star-shaped hairs. The leaves are linear to narrowly egg-shaped, {{cvt|6–20|mm}} long and {{cvt|1–2|mm}} wide on a short petiole, usually with stipules {{cvt|1.0–2.5|mm}} long at the base. The edges of the leaves are rolled under, and both surface are covered with star-shaped hairs, more densely so on the lower surface. The flowers are {{cvt|8–10|mm}} in diameter, arranged in cymes of three to six on a peduncle {{cvt|4–12|mm}} long, each flower on a pedicel {{cvt|4–7|mm}} long. There is a single egg-shaped bract and three lance-shaped bracteoles. The pink, petal-like sepals are deep red at the base, and joined for most of their length, each with three to five hairy ribs, and covered with star-shaped hairs. There are tiny, deep red petals and staminodes. Flowering occurs from June to November.<ref name="Blake">{{cite book |last1=Blake |first1=Trevor L. |title=Lantern bushes of Australia; Thomasias & allied genera : a field and horticultural guide |date=2021 |publisher=Australian Plants Society, Keilor Plains Group |location=Victoria |isbn=9780646839301 |pages=234–235}}</ref><ref name="FB" />
