''Felicia westae'' is a sparsely branched shrub growing up to tall, that is assigned to the family Asteraceae. The lower parts of the stems have lost their leaves and the upper part has many crowded, upwardly angled and curved, alternate leaves pressed against the stem, with the edges curled inward. The flower heads form at the tips of the branches, each about 3 cm (1 in) across, with about twenty purplish blue ray florets surrounding many yellow disc florets.

Description

''Felicia westae'' is a low, up to high, sparsely branched shrub. The lower parts of the stem are largely hairless, the higher parts are crowded with arched upturned leaves. The leaves are line- to lance-shaped, long and 1–1 mm (0.04-0.06 in) wide, the surfaces hairless, and the bristly serrated margins curled upward and towards each other. The

s (or phyllaries) that together form the so-called involucre, which is up to in diameter. These bracts are of different length, lance-shaped, about long and approximately 1 mm (0.06 in) wide, with a bristly margin and glands. Each head contains about twenty female ray florets, each with closed, tubular part at the base that is hairy in its upper part and a purplish blue strap of about long and wide. These surround numerous bisexual disc florets with a yellow

The eventually yellowish brown to reddish, dry, one-seeded, indehiscent fruits called cypselae are oval in outline, about long and wide, with a weak ridge along the margin. The cypselae of the ray florets are hairless, those of the disc florets short-haired.

Distribution, habitat and conservation

''Felicia westae'' was known from many observations near Humansdorp in the southwest of the Eastern Cape province of South Africa, where it occurred on river banks in low-lying areas near the coast. It grows in vegetation types called Tsitsikamma Sandstone
Fynbos Fynbos (; meaning fine plants) is a small belt of natural shrubland or heathland vegetation located in the Western Cape and Eastern Cape provinces of South Africa. This area is predominantly coastal and mountainous, with a Mediterranean clim ...
and Garden Route Shale Fynbos. It is considered to be endangered because its habitat suffered from expanding agriculture and timber plantations, while on the riverbanks it is out-competed by invasive plant species. After 1944 it was no longer found until it was rediscovered in 2015 along a few tributaries of the Tsitsikamma River.
