Martin. — Pferidophyfes of Banlcs Peninsula . 321 



Dryopteris glabella C. Chr. Balgueri Valley, R. M. L., W. M. ; Maori Kaik, 

 Newton's Vallev, Grehan Vallev, and Rowe's Bush on Adam's Point, 

 W. M. 



Dryopteris punctata C. Cr. Common on the margins of the bush. 



Dryopteris pennigera C. Chr. Common in shaded stream-beds below 1,000 ft. 



Dryopteris velutina 0. Ktz. This handsome fern still grows where it was 

 discovered by Raoul. Akaroa, Rowe's Bush, Maori Kaik, W. M. 



Polypodium BiUardieri (Willd.) C. Chr. {^= P. australe Mett.). Common on 

 rocks and tree-trunks all round the summit. 



Polypodium pustulatum Forst. f. Long Bay, D. G. R. ; Stony Bay, W. M. 



Polypodium grammitidis R. Br. Common on tree-trunks and on rock near 

 the summit from Stony Bay to Wainui. Specimens from Le Bon's 

 measured 12 in. in length. 



Polypodium diversifolium Willd. Everywhere abundant. 



Cyclophorus serpens C. Chr. Akaroa, Peraki, Island Bay, W. M. 



Leptopteris hymenophylloides Presl. Abundant in the denser areas of bush, 

 as at Peraki, Le Bon's, Stony Bay, &c. It also grows in the beech 

 forest at the head of Balgueri Valley, facing full to the sun. 



Ophioglossum coriaceum A. Cunn. Hills behind Wainui, ridge between 

 Le Bon's and Hickory, R. M. L. 



Botrychium australe R. Br. Grehan Valley. Mr. G. Penlington conducted 

 me to a spot where it formerly grew abundantly, and we were fortunate 

 enough to find a specimen about 400 ft. above sea-level. Brasenose 

 (lower levels), G. P., D. G. R. 



Lycopodium varium R. Br. Waikerikikeri, R. L. M. ; head of Le Bon's and 

 Barry's Bays, W. M. Specimens superficially resembling L. BiUardieri 

 Spring were obtained by me growing as epiphytes both at Stony Bay 

 and at Le Bon's. At first I could find no fertile fronds ; and, referring to 

 barren fronds sent to him, Dr. J. E. Holloway wrote me, "Almost cer- 

 tainly L. BiUardieri.'' Writing later, after I had secured fertile fronds, 

 he says, " T agree with you that the fertile plants you send are more of 

 the form of L. varium than of L. BiUardieri. These two species grade 

 into one another, so that it is quite possible to speak of an intermediate 

 form as being a variation of the one as much as of the other. Seeing that 

 they are recognized as two distinct species . . . and judging from 

 the fertile specimens they deserve the name L. varium.''' The barren 

 fronds were obtained from Griselinia littoralis and Podocarpus totara, 

 while the fertile plants were epiphytic on Dicksonia fibrosa. All had 

 V a tendency to upward or erect growth, but the longer fronds drooped 

 by reason of their weight. 



Lycopodium BiUardieri Spring (?). See proceeding note. 



Lycopodium scariosum Forst. Head of Long Bay and Stony Bay, D. G. R., 

 W. M. 



Lycopodimn volubile Forst. f. Wainui hilltops, above Le Bon's Bay, near 

 Hilltop Hotel, R. M. L., W. M. 



Tmesipteris tannensis Bernh. This pteridophyte grows plentifully in the 

 stream-valleys at Akaroa, and more sparingly at Le Bon's and Peraki. 

 Plants over 1 ft. in length are not uncommon on the tree-fern stems 

 ' in Newton's Valley at Akaroa. 



Azolla rubra R. Br. Pigeon Bay, W. M. This little floating water-fern 

 frequents the surface of fairly stationary water, which is seldom pro- 

 vided in the Akaroa area, hence the probable reason for its not having 

 been reported previouslv.
