This splendid plant, in the stoves of the Royal Gardens, has 
not, with fertile fronds four feet in length, formed a stem or 
erect caudex more than six and a half inches high, and four 
inches in diameter. In Ecuador, Mr. Spruce speaks of it as “a 
tufted Fern, two to five feet high.” Mr. Gustav Mann describes 
the caudex in Fernando Po as “stout and erect ;” but in Brazil 
it would appear to be truly a Zree-Fern, of which the caudex is 
twelve to eighteen feet high; at least, as represented on the same 
plate with Alsophila armata, its trunk is equal in height with 
it, which is described to be of that size. From the summit 
of the caudex springs a noble tuft of stipitate fronds, four to
