Scientific Name:Polybotrya

Type Species. Polybotrya osmundacea Humboldt & Bonpland ex Willdenow, of wide distribution in tropical America.

A neotropical genus of about 40 species, of which only one has been found in Puerto Rico. This is sometimes separated in a genus Olfersia on the basis of its 1 -pinnate blades, parallel venation, and diflerences in rhizome anatomy. It is also alleged to be terrestrial, not scandent, but this is often not true (see photograph in Tryon & Tryon, 1982: 537). The generic name is derived from the Greek po/y, many + botrys, bunch or cluster, referring to the clustering of the sporangia on the spurlike fertile segments.
