Another species complex in Attalea includes A. speciosa and related species . Henderson ( 1995 ) recognised A. speciosa and A. spectabilis , considering the latter to either be an acaulescent form of A. speciosa or a hybrid between it and A. microcarpa . Govaerts and Dransfield accepted A. spectabilis , but Glassman considered it a dubious taxon . Attalea vitrivir was recognised as a distinct species by Michael Balick and coauthors ; Glassman and Govaerts and Dransfield concurred , but Henderson considered it part of A. speciosa . Glassman also described a fourth member of this group , A. brejinhoensis , and it is accepted by Govaerts and Dransfield .
