Cardamine lilacina has rounded ovate or reniform leaves (basal) that are nearly always pinnate with 1-3 rows of ovate shaped pinnae. it grows in a wide range of habitat from lowland grassy woodlands to alpine herbfield, see below.

Cardamine franklinensis has spathulate leaves that are mostly entire but occasionally pinnate, basal leaves form a dense rosette. If pinnate then the terminal pinnae is elliptic, it is the only cardamine species in the mountains with this leaf shape.

From the research i've done c.franklinensis hasn't been commonly recorded anywhere but is known from the slopes of a number of act mountains, i think the type localitly is mt franklin (which is to the north of gingera) so it may be more or less act endemic.

these two sightings are a good comparison.

Looks like I started something with this sighting, which I almost didn't post - it being close to sighting 4449068 and the latter having better flower images. But Ciaran's comment on 4449068 prompted me to post this one because of the good view of the leaves. Very pleased that it stimulated you to have a revisit of some of the lilacinas.
