 Its small population size and extreme isolation from other members of the genus make "A. crassispatha" scientifically interesting.This isolation was supported by a molecular phylogeny of the group published in 2009.Alan Meerow and colleagues found "A. crassispatha" to belong to a clade that included the ""Scheelea" clade" and the two ""Orbignya" clades", but that it was a sister to both groups.
