  abstract = {{B}ackground and aims - {I}xora margaretae, endemic to {N}ew {C}aledonia, is a flagship for the archipelago's sclerophyllous forests. {R}ecently, three populations of an {I}xora resembling {I}. margaretae were found in humid forest. {M}ethods - {G}enetic studies using {SSR} markers and morpho-anatomical studies of vegetative and reproductive features are provided. {R}esults - {M}olecular results show that the genetic distances between and within {I}xora margaretae dry and humid stands vary similarly. {A}ccordingly, humid stands are interpreted as a part of the broad newly delimited {I}. margaretae, occurring in fragmented habitats. {M}orpho-anatomical data show that several features, such as the bark types, the individual height, and the fruit fleshiness result from genetic variability expressed under environmental constraints. {H}owever, other features are interpreted as acclimatisation of populations to local conditions, such as the convergent erected receptaculum pollinis for dry and humid stands, obtain by two different anatomical processes. {A}ll data suggest that {I}. margaretae is a species showing genetic isolation and relative adaptations to environments of populations in both humid and sclerophyll forests. {T}his illustrates potential ongoing speciation processes for several populations in both forest types. {A} scenario showing the successive habitat modifications from humid to sclerophyll forests that can explain the persistence of the species in sclerophyll areas is proposed.},
