| Tasmania has
eight native and two introduced species of Cardamine (bittercress).
They are smallish species found in shady places or on river banks or
similar wet places. The species are often very difficult to
distinguish. The two introduced species can be picked by having some
hairs on the stems and/or leaves (you need a hand-lens or
microscope). C. tenuifolia is easily identified by its habit
(a trailing swamp plant). C. astoniae is a prostrate alpine
plant with a stolon. The remaining species are fairly similar, and
further research may result in reclassification of these species
(into more or less species).
