Distribution and ecology
Found in an area defined by the Bunya Mts in Qld to the north and Kyogle in NSW to the south. Specimens below the arrow head in the AVH generated map above are presumably misidentified or wrongly plotted.
S. limitare occurs in grassy eucalypt forest adjacent to rainforest edges
Border Ranges Nightshade
Closest to S. amblymerum but differing from that species by
- longer pedicels (11-20 mm long in flower, 16-20 mm in fruit), compared with 5-10 mm in flower and 9-13 mm in fruit for S. amblymerum
- ovary with glandular and stellate hairs compared with glandular hairs only in S. amblymerum
