Tetramolopium remyi is a prostrate, decumbent, or rarely upright (erect) shrub that grows 10 – 40 cm tall. The stems are apically and intricately branched, often appearing dichotomously branched. Young stems are capitate glandular and scabrid. The leaves are sclerophyllous, linear, and strongly involute in mature foliage, while oblanceolate to spatulate in juvenile foliage and measure 12 to 34 mm long and 0.5 to 1 mm wide. The leaves are glandular punctate and sparsely strigose, with entire and strigose margins. The flower heads are solitary, with 2.7 to 16 cm long peduncles, capitate glandular with short, stout hairs and filiform bracts. The involucre is broadly hemispherical, 5 to 7 mm high, and 9 to 15 mm in diameter, with 60 to 80 linear-lanceolate bracts that are capitate glandular abaxially and marginally, scarious hyaline-margined, erose at the apex, and acuminate. The receptacle is 2.7 to 5 mm in diameter. The ray florets are white, 4 to 6 mm long, 0.4 to 0.7 mm wide, and number 150 to 250 per head in two series. The disk florets are functionally male, numbering 70 to 100 per head, with yellow corollas that are narrowly funnelform and 3.5 to 4.5 mm long, with a tube that is 1.5 to 2 mm long. The anther appendages are short-deltate, 0.04 to 0.05 mm long, and the pappus is white, 2 to 3 mm long. The achenes are oblanceolate, 2 to 3 mm long, with fertile achenes 0.5 to 0.9 mm wide. They are glandular strigose with amber-colored glands, and the faces are 1 to 2-nerved. It occurs in lowland dry shrubland on dry, exposed ridges or flats between 50 – 550 meters.
