Published infrageneric classifications ofCoccothrinax are based only on Cuban species. To provide an inclusive categorization ofprovisional infrageneric groupings for easy recognition in future field and herbarium studies, we compared all species in the genus with statistical, phenetic, and cladistic techniques. Statistical analyses indicated that 22 of160 characters extracted from the published literature would be useful for phenetic and cladistic analyses. Phenetic analyses produced three distinct clusters of taxa. Cladistic analyses suggested that two ofthe phenetic clusters are paraphyletic and the third is monophyletic. The two paraphyletic clusters were also more plesiomorphic than the monophyletic cluster. Cladistic analyses further indicated that most ofthe 22 characters were highly homoplasious, and only the following were reliable for classificatory purposes atthe infrageneric level: loss oftransverse veins in the leaf, elongation of the leaf sheath strands, fusion of sheath strands into spine-like processes, and tan, corky fruits. The recognizable groups are as follows: Argentea Group (1 complex, 6 spp., paraphyletic); Argentata Group (2 complexes, 10 spp., probably paraphyletic)-C argentata complex (8 spp., paraphyletic), C crinita complex (2 spp., monophyletic); and Pauciramosa Group (4 complexes, 31 spp., probably monophyletic)-G. miraguama complex (11 spp., probably monophyletic), C pauciramosacomplex (11 spp., paraphyletic), Haitiella
complex (2 spp., monophyletic), species incertae sedis (7 spp.).
