  abstract = {{P}ycnandra is a genus of {S}apotaceae ({C}hrysophylloideae), restricted to {N}ew {C}aledonia, and includes similar to 60 species. {T}he genus is a member of the monophyletic {N}iemeyera complex of {A}ustralia and {N}ew {C}aledonia and it is characterised by the lack of staminodes and a fruit containing a single seed, plano-convex cotyledons and absence of endosperm. {I}n {N}ew {C}aledonia, several segregate genera have been recognised, but weak cladistic support for these groups and homoplasious morphology renders a narrow generic concept untenable. {I}nstead, a broad generic circumscription of {P}ycnandra with an infrageneric classification recognising the subgenera {A}chradotypus, {L}eptostylis, {P}ycnandra, {S}ebertia and {T}rouettia results in a stable nomenclature. {H}ere we revise {P}ycnandra subg. {A}chradotypus that includes 14 species, of which five ({P}. belepensis, {P}. blaffartii, {P}. bracteolata, {P}. glabella, and {P}. ouaiemensis) are described as new. {M}embers of subg. {A}chradotypus are distinguished from other subgenera on the basis of a character combination of two stamens opposite each corolla lobe (except {P}. litseiflora), glabrous leaves (except {P}. belepensis and {P}. decandra), a distinctive reticulate tertiary leaf venation (except {P}. comptonii), and sepal-like bracts that often are borne along the pedicel. {A}ll species are restricted to {G}rande {T}erre except for {P}. decandra, whose distribution also extends to nearby {A}rt {I}sland ({B}elep {I}slands), and {P}. belepensis, which is endemic to that same island. {T}he members grow in a wide range of vegetation types from dry maquis to humid forest, from sea level to the highest mountain massif, and on ultramafic soils to schist and greywacke (not limestone). {B}ecause of past and present threats such as mining, logging and. re, preliminary {IUCN} {R}ed {L}ist assessments are provided for all species. {F}ive taxa ({P}. chartacea, {P}. decandra subsp. decandra, {P}. glabella, {P}. litseiflora, and {P}. neocaledonica) are proposed the {IUCN} status {E}ndangered, and {P}. belepensis and {P}. ouaiemensis are proposed to be {C}ritically {E}ndangered. {W}e suggest that some locations where these species occur should be given protection in the form of nature reserves.},
