Guianodendron praeclarum is a South American legume endemic to the Guiana Shield. It is the only member of the genus Guianodendron. It has been segregated from Acosmium based on its unique combination of vegetative and floral traits,{{cite journal |vauthors=Rodrigues RS, ((de Azevedo Tozzi AMG)) |year=2006 |title=Guianodendron, a new genus of Leguminosae from South America |journal=Novon |volume=16 |issue=1 |pages=130–133 |doi=10.3417/1055-3177(2006)16[129:GANGOL]2.0.CO;2 |url=http://www.repositorio.unicamp.br/handle/REPOSIP/68536 }}{{Dead link|date=December 2024 |bot=InternetArchiveBot |fix-attempted=yes }}{{cite journal |vauthors=Rodrigues RS, ((de Azevedo Tozzi AMG)) |year=2007 |title=Morphological analysis and re-examination of the taxonomic circumscription of Acosmium (Leguminosae, Papilionoideae, Sophoreae) |journal=Taxon |volume=56 |issue=2 |pages=439–452 |jstor=25065799 |doi=10.1002/tax.562015 }}{{cite journal |vauthors=Rodrigues RS, ((de Azevedo Tozzi AMG)) |year=2008 |title=Systematic relevance of seedling morphology in Acosmium, Guianodendron, and Leptolobium (Leguminosae, Papilionoideae) |journal=Brittonia |volume=60 |issue=3 |pages=287–296 |doi=10.1007/s12228-008-9035-y |bibcode=2008Britt..60..287R |s2cid=43533799 }} and it is related to Diplotropis.{{cite journal |vauthors=Cardoso D, de Lima HC, Rodrigues RS, de Queiroz LP, Pennington RT, Lavin M |year=2012 |title=The Bowdichia clade of Genistoid legumes: Phylogenetic analysis of combined molecular and morphological data and a recircumscription of Diplotropis |journal=Taxon |volume=61 |issue=5 |pages=1074–1087 |doi=10.1002/tax.615012 }} It is the only member of the genus Guianodendron.{{cite web | url = http://www.ars-grin.gov/cgi-bin/npgs/html/splist.pl?28596 | title = GRIN species records of Guianodendron | author = USDA | author-link = USDA | author2 = ARS | author2-link = Agricultural Research Service | author3 = National Genetic Resources Program | date = | website = Germplasm Resources Information Network—(GRIN) [Online Database] | publisher = National Germplasm Resources Laboratory, Beltsville, Maryland | accessdate = 12 February 2014 }}
