Romulea sabulosa is a local endemic that grows in large populations in renosterveld on clay and sandy soils on the Bokkeveld Escarpment west of Nieuwoudtville. It is closely related to R. monadelpha , which has similar large red flowers with a pale cup and prominently marked with dark blotches at the base of the tepals. The leaf anatomy of both species is also similar, with a band of subepidermal sclerenchyma along the ribs. The species are best distinguished by details of the filaments. In R. sabulosa the filaments are usually pale greenish and taper from a pubescent base as in most other species of Romulea while in R. monadelpha the black filaments are either united into a short, stout glabrous column or when free are oblong and do not taper toward the apex. Another differences is in the peduncle, which in R. sabulosa is subterete and remains suberect in fruit, but in R. monadelpha is somewhat stouter, with the upper side conspicuously flattened, and is curved in fruit.
