%X a total richness of 602 specifc and infra-specifc taxa is reported for the locality of altos de chicauma, situated in the metropolitan region£¿s coastal mountain range, chile (33o s), between 500 and 2.200 m of altitude. chile£¿s endemic taxa constitute 41% and the southern cone endemics equal 66% of the total flora, while 14% corresponds to alien flora. the total flora is characterized according to its presence in seven habitat-types. a commented systematic list is presented where each taxon is characterized according to its growth habit, geographic origin, relative frequency, and presence per habitat-type in chicauma. herbarium material supporting the presence in this locality is indicated for 572 taxa (95%). the total flora and the habitat-types£¿ partial floras were characterized according to their richness, origin and biologic-types compositions. a similarity analysis between the habitats£¿ native floras indicates that the species composition differs signifcantly to the rest in £¿high-mountainous hydric environments£¿, £¿creeks and ravines£¿, £¿xeric£¿, and in the pairs, £¿valley sclerophyllous - montane sclerophyllous£¿ and £¿deciduous - high-mountainous£¿ habitats. the presence of 14 endangered species, nine central chile£¿s coastal mountain range endemics, 13 metropolitan-valparaiso regions£¿ mountain endemics, and fve distributional limits are reported for this locality.
