Conostylis androstemma (common name trumpets) is a tufted perennial plant species in the family Haemodoraceae. It is endemic to the south-west of Western Australia. Plants grow to between 10 and 30 cm high and produce cream to pale yellow flowers between May and August in the species' native range.

Description

Conostylis androstemma has green, hairless, terete leaves that are 10–30 cm (3.9–11.8 in) long and about 1 mm (0.039 in) in diameter. The flowers are borne on pedicels that are 4–6 mm (0.16–0.24 in) long, with bracts 8–10 mm (0.31–0.39 in) long and 2 mm (0.079 in) wide at the base. The flowers are white to cream-coloured or yellow, 25–45 mm (0.98–1.77 in) long, hairy and radially symmetrical with lobes that are 15–22 mm (0.59–0.87 in) long. The six stamens are in one level, the anthers 11–12 mm (0.43–0.47 in) long and the style 33–45 mm (1.3–1.8 in) long. Flowering occurs from May to August. The plant resprouts from its rhizomes, after fire.

It is easily distinguished from Conostylis argentea by its terete hairless leaves.
