    Anogramma leptophylla is a variable species as to size and nature of ultimate segments. Frond segments vary from flabellate to long and finely dissected (variant known as A. guatemalensis; see Smith, 1981; R. Tryon, 1962; Tryon &Tryon, 1982). Nakazato and Gastony (2001) have shown A. guatemalensis to be nested within A. leptophylla.
