Oss. The various forms presented by the Ceropferis group 
of Gymnogramma, render it very difficult to determime them as 
distinct species. They are very generally distributed over the 
warm parts of America, and almost every locality presents forms 
somewhat different, such as the pinnules being more or less 
entire or divided, and in the teeth or serratures being more or 
less obtuse or acute, so also the farina, which characterizes this 
group, has different shades of colour even in forms that may be 
considered as belonging to one species. It has been stated that 
in cultivation hybrids have been raised, but of this I have no 
proof, and as I possess native specimens of forms said to be 
hybrids, I cannot be persuaded that: such have been produced 
in gardens. |
