ADIANTUM. 53 



Hab. New Zealand, Northern Island, Colenso, J. D. Hooker, Dr. Sin- 

 clair, ^c. Banks' Island (off the southern or Middle Island), Raoul. — Dr. 

 Hooker, on his return from the Antarctic voyage, broui^ht home copious 

 specimens of this species, gathered by Mr. Colenso and himself in N. Zea- 

 land, and Mr. Raoul has named it and clearly defined it in his beautiful and 

 accurate work above quoted. The term he uses for the pinnules ("oblique 

 cultriformes ") is singularly applicable to the majority of the pinnules as dis- 

 tinguishing the species from its nearest affinity A. Cunnincjhami {A.formosum 

 of N. Zealand botanists), with which it quite agrees in the position and 

 form and colour of the involucres: — but the plants are much larger (2 — 2^ 

 feet, including the stipes), never glaucous, but pale and rather bright olive- 

 green beneath, even when dry ; the stipes too is singularly rough, almost 

 muricated, scaly at the base where it rises from the elongated stout caudex. 

 A. affine (our No. (55) is a much smaller more slender and more pedate plant, 

 with very thin membranous pellucid pinnules, and more membranous white- 

 coloured involucres, seated in a deeper sinus. Some of our specimens of A. 

 fulvum have rigid slender hairs or aciculi like those of -4. affine, but they 

 are deciduous or not constant nor common.
