Sabal
Sabal is a genus of New World palms (or fan-palms). Currently, there are 17 recognized species of Sabal, including one hybrid species.
The species are native to the subtropical and tropical regions of the Americas, from the Gulf Coast/South Atlantic states in the Southeastern United States, south through the Caribbean, Mexico, and Central America to Colombia and Venezuela.
Members of this genus are typically identified by the leaves which originate from a bare, unarmed petiole in a fan-like structure. All members of this genus have a costa (or midrib) that extends into the leaf blade. This midrib can vary in length; and it is due to this variation that leaf blades of certain species of Sabal are strongly curved or strongly costapalmate (as in Sabal palmetto and Sabal etonia) or weakly curved (almost flattened), weakly costapalmate (as in Sabal minor). Like many other palms, the fruit of Sabal are drupe, that typically change from green to black when mature.
The name Sabal was first applied to members of the group by Michel Adanson in the 18th century. Previous names that this genus was associated with include Corypha, Chamaerops, Rhapis. This section highlights important phylogenetic work done within the genus Sabal.
In 1990, Scott Zona outlined key morphological and anatomical characters that he used to analyze species relationships of Sabal. Through this analysis of characters, Zona produced a cladogram that portrays evolutionary relationships amongst 15 species of Sabal. Based on the distribution of species within his cladogram, Zona recognized four distinct clades. The clades within his study include:
Sabal bermudana, Sabal palmetto, Sabal miamiensis, and Sabal etonia
Sabal maritima, Sabal domingensis, Sabal causiarum, Sabal maurittiformis, Sabal yapa, Sabal mexicana, and Sabal guatemalensis
