Our specimens of this South African Fern are not in that state of perfection as to render it quite 
evident that there is an involucre present with the sori: and it is doubtful whether this plant would 
not with more propriety be arranged with the genus Z'emiis. At first the sori of fructifications are 
decidedly in lines, close to the margin; but in age the capsules spread, so as to cover the whole 
back of the frond ; and in that state the plant might well be taken for an "Aerostichum.
