Of this genus, Willdenow describes eleven species, 
all of which are taken from the Onoclea of Swartz, (Sy- 
nops. Fil.) and Labill. (Nov. Holl.) and. Bory. (Jtin. ) 
In affinity, they approach so near to Onoclea, that it is 
difficult to give them a determinate and distinct charac- 
ter, as must be the case in all natural genera, when the 
intermediate links of the series are discovered, The in- 
volucrum is continuous on each side of the frond, and

fruitful fronds are also pinnate, and sy sting 8 are li- 
near, and entire. ‘The stem is erect, and four feet high. 
The sterile fronds are two. or three feet long ; 
fruitful ones shorter, and their pinne very narrow, This 
fine species, like most of the other arborescent ferns, is 
unknown in our collections, Willdenow is in doubt

Swartz had associated the respective species with Adian- 
tum; although they ought, he observes, in consistency” 
with the Linnean character, to have been referred to 
Peeris, with which indeed iro Rae an evident affinity. 
Lindsea received its name in honour of Lindsay, an in- 
gens botanist of Jamaica. ( Trans. Lin.
