Threats |
| Romulea komsbergensis is restricted to seasonally moist clays, a habitat that is undergoing ongoing loss due to crop cultivation. |
Population |
This species is known from nine locations, but there are large areas of suitable, but unexplored habitat between known locations, and therefore it is highly likely that more subpopulations exist.
