Tasmania
has nineteen native species and nine introduced species of Ranunculus
(buttercups). These vary in habit and habitat, but are often plants
with palmate or palmately lobed leaves. They often grow in wet places (such as boggy ground), although some are aquatic and others
live in dry places. All are herbs with yellow flowers, and most have
leaves that are palmate or palmately lobed. Ranunculus species can be difficult to identify (so be
patient with this poor key). Two introduced species (R. arvensis
and R. scleratus) are not included in the key because they
are very rare or possibly extinct.
