Willdenow was only acquainted with the fructified state of the frond 1 but it is in the sterile 

 fronds that the most striking differences are found to exist between this species and D. alata and 



■ 



D. elliptica. Some of the fronds which Mr. Guilding has sent us, including the stipes, measure not 

 less than six feet in height, and almost a foot and a half in diameter in the widest part. The pinnae 

 are remarkable for their pale colour, their shining surface, and rigid texture. In drying, the knots 

 at the insertion of the leaves, probably, in a certain degree, disappear, for they are by no means so 

 visible in our specimens as in Plumier's figure.
