Distribution and Ecology

Occurs in CEQ, only know from Gloucester Island, east of Bowen. It occurs in Araucarian vine thickets on slopes amongst granitic boulders.

Natural History & Notes

This species is similar to Capparis lasiantha (stamens 10-22) and Capparis sarmentosa (stamens 19-22) but differs from both in the fewer number of stamens (8 in C. batianoffii ). The leaves of C. sarmentosa are mostly ovate to circular cf. oblanceolate to narrow elliptic in C. batianoffii. Capparis lasiantha has a tomentose rather than woolly stem and leaf indumentum, mostly larger leaves (2 -9 cm in C. lasiantha cf. 1-2 cm in C. batianoffii ) and lacks the recurved leaf margin of C. batianoffii.
