The linear leaves, about 20-200 per plant, are scattered along the elongate, glabrous stems.

Inflorescences are 2.6–6 cm long and produce a single yellow or orange flower that blooms in June and July in the southern hemisphere.

Its habitat is recorded as being moist sandy soils on flat or gently sloping terrain, sometimes in areas dominated by Melaleuca species.

S. trichopodum is most closely related to S. pedunculatum, though it differs by its much larger flower and its cauline leaves instead of terminal rosettes for S.

[1] In his revision of the subgenus Andersonia, Anthony Bean noted that the conservation status as data deficient, but also mentioned that it is clearly rare.
