Making iu all a gross total of 53 species of ferns found growing together 

 in a very small plot of ground, being several more than the whole number 

 of species of ferns found in the British Islands. And I have good reasons 

 for believing that the following additional species may yet be found there 

 also, as I know they are growing in profusion not far off, viz., — Lomaria 

 nigra, Poly podium cunninghamii, Acliantum diaphanum. 



Of one thing respecting this beautiful and justly-prized order of plants 

 I feel pretty certain, namely, — that there are several still unknown and 

 undiscovered species yet to be found in New Zealand. :;: For I am yearly 

 becoming more and more convinced of the correctness of my old belief! in 

 the very circumscribed locality of not a few of our New Zealand plants ; 

 and, therefore, as the many still uuexplored mountains and valleys, forests 

 and plains of New Zealand come to be visited and known, — especially to 

 men of science, — their many botanical novelties will become known also ; 

 though I much fear that cattle and fire, and introduced plants, will cer- 

 tainly destroy many. Such, indeed, has been the case here already in not 

 a few places in Hawke's Bay.

Class I. Dicotyledons.

Carmichcdia corrugata, sp. nov. 



An exceedingly small glabrous shrub, 2-3 inches high ; branches leafless, 

 1-2 inches long, 1 line wide, mostly simple, rarely forked, flat, linear, 

 obtuse, striated (almost ridged) and grooved longitudinally, slightly flexuous, 



* As a further proof, I may here mention that I have this year detected four new 

 species of ferns, — two of them being also tree-ferns, — in another unfrequented portion of 

 these grand old forests, some ten miles south of this spot ; of which a full description will 

 be given in a future paper.
