Discussion

Sacoila squamulosa is widespread in tropical and subtropical America. Although often overlooked in Florida, it was included in the range of Stenorrhynchos squamulosum (M. Nir 2000), and details were given for its inclusion in the Florida flora (P. M. Brown 2000b). That resulted in determining that a large stand of nonconforming Sacoila in Marion County was indeed this species. It is a tall and handsome plant that, upon close examination, has the unmistakable scurfy or hoary dots instead of the short pubescence of Sacoila lanceolata. This is one of the most recent additions to the orchid flora of Florida and the United States. Plants have been either overlooked or not well distinguished from the more common S. lanceolata var. lanceolata. Knowledge of the range in Florida is incomplete, pending further study.
