Justification
Streptocarpus lilliputana has an extremely narrow distribution, with an EOO of 18 km². One of three known subpopulations is potentially threatened by habitat degradation due to firewood harvesting.

Description
Rock seepages in deeply shaded forested river gorges.
Threats
Plants in one small fragment of scarp forest near the Lupatana River Mouth are potentially threatened by habitat degradation. Firewood is harvested from this forest patch, and removal of trees, on which this shade-loving species is dependent, may lead to the decline of plants in exposed sites (Bellstedt and Edwards 2004). The other two subpopulations occur on inaccessible cliffs, and are not under threat.
Population

This species is known from three subpopulations, two along the Lupatana River Gorge, and one on the upper reaches of the Mkozi River, about 15 km to the southwest of the Lupatana River (Bellstedt and Edwards 2004). One subpopulation near the mouth of the Lupatana River is very small, consisting of about 15 plants, while the second subpopulation further upstream is much larger. Similar habitat in river gorges between the Lupatana and Mkozi rivers have not yet been surveyed for this species, and it is likely that more subpopulations exist in these areas, which are more difficult to access (Bellstedt and Edwards 2004).
