[2] The genus has a single species Pseudoprospero firmifolium,[1] which is endemic to South Africa (the Cape Province, KwaZulu-Natal).

[3] Pseudoprospero firmifolium grows from an underground bulb whose tunic has dry, paper-like outer layers.

Individual flowers have white to lilac tepals which are joined at the base and persist into the fruiting stage.

[4] From the 1970s onwards, Franz Speta and co-workers split up the broadly defined genus Scilla, placing many of its species into separate genera.

[1] Subsequent studies have confirmed that Pseudoprospero firmifolium is distinct not only from Scilla but from all other genera in the tribe Hyacintheae (or the subfamily Hyacinthoideae for those who accept the family Hyacinthaceae),[6] being placed in its own subtribe.
