Having received some fine specimens of this noble Fern from Jamaica, as well as from St. Vin- 
cent and Trinidad, we could not resist the temptation of giving a figure of it, although a very good 
one, of a single fertile frond, exists in the rare and costly work of Humboldt and Kunth. 
'The species most nearly allied to this is the 24d. ob/iquum of Sprengel, or rather of Willdenow ; 
only that the latter seems to have confounded the zd. lucidum with it. It is, however, much smaller 
than 4. macrophyllum, less angular towards the base, more glaucous beneath, with more numerous 
sori and a pubescent rachis.
