  abstract = {{I}n many regions of {N}ew {C}aledonia, the ultramafic maquis appears to possess fire adapted traits in addition to being adapted to substrate conditions ({M}orat et al, 1986 b). {S}election of species in these communities may favour fire adapted taxa over ultramafic species. {A} phytosociological survey was conducted in #{G}ymnostoma deplancheanum$ communities in southern {N}ew {C}aledonia to identify floristic changes which may suggest a fire related succession pattern. {F}ire adapted responses of the more common species were also recorded for these communities to both quantify the succession pattern and possibly identify the biogeographic origins of fire tolerance in {N}ew {C}aledonia. {MDS} ordination of the floristic survey combined with a succession index best explains the variance in the data suggesting the pattern is successional. {T}here appears to be 4 different floristic groups which occur at different times since fire. {T}he first early colonist phase is dominated by vegetative regenerating genera shared largely with the {A}ustralian region. {L}ater succession steps are dominated by obligate seeders which facilitate subsequent colonisation of sensitive maquis and forest taxa. {I}t appears that fire adaptation in {N}ew {C}aledonian maquis originated from ancestral {G}ondwanan tax prior its separation. {T}hese sclerophyllous taxa may have increased their radiation on ultramafics during fire promoting dry periods. {A} second evolution possibly took place in {N}ew {C}aledonian forest taxa in response to dry conditions and led to the creation of fire adapted endemic genera.
