specific names given by Swartz and LabHIardi^re simultaneously to 

 this lovely plant are not well applying to the generality of its forms. 



Cyathea dealbata. 



Swartz, Synops. Pilio. 140 & 365 ; Willd. Spec. Plant, v. 495 ; Ack Rich. Toy. 

 de I'Astrolabe, 11, t. 10 ; Hook. Spec. Filic. i. 27 ; J. Hook. Flor. Nov. 

 Zeel. ii. 7 ; Ealph ia Proceed. Limi. Soc. iii. 163 & 164 ; Polypodium 

 dealbatum, Forst. Prodr. 454. 



Common in woods of the Chatham-Islands. 

 The serratures or crenatures of the ultimate lobes of the frond 

 are often very faint 



Cyathea Cunninghami. 



J. Hook, in Hook. Icon. Plant. 985 ; Flor. Nov. Zeel. ii. 7 ; Ralpi in 

 Proceed. Linn. Soc. iii. 163 & 167. 



Common In the woods of the Chatham-Islands, where it is called 

 by the natives "Ponja." 



If to the plants in our collection a right interpretation has been 

 given this species differs from C. meduUaris besides in some of the 

 characters pointed out by Dr. Hooker in slightly smaller more 

 tender sori, which seem not so generally distributed over the whole 

 but otily along the lower part of the underpage of the pinnule- 

 segments, in more slender sporangia with a less conspicuous ring. 



C. Smithii, according to specimina from Canterbury, has generally 

 but few sori attached to the midnerve of the lower part of each of 

 the pinnule-segments, and the small indusium retracted to a shallow 

 cup, from which the prominent receptacle comes conspicuously in 

 view. 



DiCKSONIA SQUARKOSA. 



Swartz, Synops. Filic. 136 & 355 ; Schkuhr's Farrnkrseuter, 124, 1. 130 ; Hook. 

 Spec. Filic. i. 68 ; J. Hook. Flor. Nov. Zeel. ii. 9 ; Ealph in Proceed. Linn. 

 Society, iii. 169 ; Trichomanes squarrosum, Forst. Prodr. 476. 



Chatham-Islands. 



The specimina of this Dicksonia before us are scarcely sufficient 

 for exact identification. 



ASPLENIUM FALCATUM.
