Notes:—Apparently, the only difference between A. martinezi and A. hondurensis is the presence of carinae on petals of the former; however, in other aspects, both plants are phenetically indistinguishable, they share ecological affinities and grow in the Yucatan Peninsula biotic province; thus, the two names are considered conspecific.
