This, like the Trichomanes lucens, is liable to vary much in size. Our largest specimens are 

 from Guadeloupe, gathered by Mr. Parker. Those here figured are from St. Vincent, and are 

 intermediate between the largest and the smallest size. We possess some small and apparently 

 young specimens which are thickly clothed with ferruginous hair, but do not seem otherwise to 

 differ from the more common state of the plant.
