Guichenotia apetala is an erect, compact shrub that typically grows to high and wide, and has many branches. It new growth is densely covered with white, star-shaped hairs sometimes with a dark centre. The leaves are triangular to heart-shaped or arrow-shaped, long on a
petiole less than long and lacking
stipules. The lower surface of the leaves is densely covered with star-shaped hairs with a dark brown centre, giving it a scaly appearance. The flowers are borne singly or in small groups on a
peduncle long, each flower on a hairy
pedicel long, with one or two linear
bracts long and three linear
bracteoles at the base. The flowers are pendent, with salmon pink, petal-like
sepals long, prominently ribbed, and joined for three-quarters of their length. There are no petals or
staminodes and the
stamens are red. Flowering occurs from September to December and the fruit is an oblong
capsule long. ==Taxonomy and naming==
