Justification | Romulea tubulosa is a newly described species that is inconspicuous and appears to be rare, and is currently only known from two locations, with an extent of occurrence (EOO) of 37 km². It is potentially threatened by habitat degradation due to overgrazing and trampling on communal lands at one of these locations. Further field surveys may reveal it to be more widespread than currently known. It is listed as Vulnerable under criterion D. |
