30 ADIANTUM FORMOSUM. 



bourhood of Port Jackson, yet never found elsewhere, with 

 the solitary exception of Mangatainoka, (New Zealand,) where 

 it was discovered by Mr. Colenso. 



A common and easily cultivated species. 



A. formosum is an evergreen Fern with branching fronds, 

 four times pinnate. The pinnules are small, membranous, 

 rhomboidal, blunt, inciso-lobate, sterile, serrate. Rachis pubes- 

 cent; stipes long, scabrous, lateral, ebeneous, and glossy, as 

 well as the petioles; this contrasts greatly with the vivid green 

 of the pinnules. 



Sori small, with an oblong kidney-shaped indusium, usually 

 about six on each pinnule. 



The height of the frond varies from eighteen inches to three 

 feet, one half of which is naked. The colour pale green. The 

 rhizoma is slender and creeping. 



It is a species very readily propagated by spores, and also 

 by divisions of the creeping rhizoma; in short no care is requisite 

 with its propagation, as it is almost certain for seedlings to 

 spring up amongst the different plants in the house in which 

 it is cultivated. 



I am indebted to Mr. Lamb, gardener to F. Wright, Esq., 

 of Osmaston Manor, for plants of this species; and to Mr. 

 Henderson, of Wentworth; and to Mr. Norman, of Hull, for 

 fructified fronds. 



It is in the Catalogues of Messrs. A. Henderson, of Pine- 

 apple Place; Lucombe, Pince, and Co., of Exeter; Veitch, of 

 Exeter; Masters, of Canterbury; Parker, of Hollo way; Rollisson, 

 of Tooting; E. G. Henderson, of St. John's Wood; Sim, of 

 Foot's Cray; Booth and Son, of Hamburg; and Cooling, of 

 Derby.
