We are indebted to the liberality of the Horticultural Society for this, as well as for several 
other new and rare Ferns, which were gathered in different parts of the world by their collector 
Mr. Macrae. Of the present individual, however, we possess but a portion of the frond, and are 
neither able to speak as to the extent to which the whole may attain, nor to the form of its outline 
or circumscription ; nor whether, as is probable, it belongs to the tribe of the tree Ferns. It seems 
allied to the Cyathee : but what is the appearance of the involucre in a younger state, as compared 
with that which is here figured, we have no means of ascertaining. Still we possess the fructifica- 
tion sufficiently perfect to determine that it does not correspond with any hitherto described genus 
of Ferns. 
* Nomen à eras patera; from the singular appearance of the involucre.
