  abstract = {{M}ajor collections of the ultramafic flora of {G}oias, central {B}razil, were made by {B}rooks and co-workers in 1988 and 1990. {A}t the time of reports on this material in 1990-1992 much of it had been identified only tentatively and incompletely, but the area was clearly interesting for taxonomic and biogeochemical reasons. {F}urther progress has been made but still only two-thirds of the specimens are identified at the species level. {F}ollowing a third collection in early 2005, we now have 800 specimens from this area, with chemical analyses of all the plants and of more than 120 representative soil samples. {N}ew species have been found, e.g., in {P}aspalum ( {P}oaceae) and {P}terolepis ( {M}elastomataceae). {T}here is a need for more taxonomic work in genera such as {C}nidoscolus ( {E}uphorbiaceae), {L}ippia ( {V}erbenaceae), {T}urnera and {P}iriqueta ({T}urneraceae), and {V}ellozia ({V}elloziaceae). {N}i hyperaccumulation (> 1,000 mg/kg in dry plant matter) has now been found in a total of 79 specimens, representing more than 30 different species. {N}otable {N}i hyperaccumulators include {P}faffia sarcophylla ({A}maranthaceae), species of {J}usticia, {L}ophostachys and {R}uellia ( {A}canthaceae), {P}orophyllum ( {A}steraceae), several species of {L}ippia ( {V}erbenaceae), {T}urnera and {P}iriqueta ( {T}urneraceae), and a possibly new {C}nidoscolus ( {E}uphorbiaceae). {N}i hyperaccumulation has not been found in plants of the outcrops of {M}orro {F}eio or {C}rominia-{M}airipotaba; it seems to be confined to the extensive layered ultramafics of {B}arro {A}lto and the {M}acedo-{N}iquelandia areas. {T}he distribution of {N}i-values in the {B}razilian plant collection is different from that found in the {M}editerranean and {C}alifornia, where there is a clear distinction between accumulator and non-accumulator plants: in {B}razil the distribution is more continuous, and median {N}i concentrations are much greater. {A}n ultramafic hill just north of {N}iquelandia deserves to be protected because of the presence there of many of the hyperaccumulators and species probably endemic to the {G}oias ultramafics.},
