THE FERNS OF TUTIRA 



111 



one small spot on Tutira. Another fern only to be found on rock is the 

 slender, beautiful annual, Gymnogramme leptophylla. Thrice since 1882 

 it has been exceedingly plentiful on the conglomerates of central Tutira. 

 On each occasion the plant has shown itself after periods of remarkable 

 drought and heat, germination of its spores seeming only to happen 

 at a temperature above normal. Except under such conditions not a 

 single specimen has been found. It is absent or abundant, very plenti- 

 ful or undiscoverable, appearing or reappearing at intervals of years. 

 Asplenium flabbelifolium also chiefly abides on the rocks. I have got 

 specimens of many others burnt up, starved, depauperated on cliffs. 

 Their names need not, however, be given, as they grow also on sites 

 where they thrive and which they adorn by happy growth. One other 

 fern Gleichenia Cunninghamii, a forest species normally has once only 

 been found on Tutira. 



I can say of the ferns as of the grasses and orchids of the station, 

 that they have been sought for with special care. Appended are the
