two other localities in the Auckland District — one near the Waitakare 

 waterfall, where it was plentiful until the construction of the huge dam 

 for the Auckland water-supply destroyed most of the adjacent forest ; the 

 other a little to the north of the mouth of the Waitakare River. 



Mr. E. Phillips Turner informs me that a few plants of P. glaucus 

 exist in a ravine near the base of Rainbow Mountain, near Waiotapu ; and 

 that it is plentiful at Lake Waikare-iti, near Waikaremoana. The latter is 

 the most easterly locality known. 



LXXIX. Orchidaceae. 

 Thelymitra pachyphylla Cheesem. 



To this species I refer specimens of a Thelymitra collected by Mr. H. B. 

 Matthews between Erua and Makatote, to the west of Ruapehu. It agrees 

 with T. pachyphylla in the broad and flat erect staminodia, the margins of 

 which are furnished with simple or branched fimbriae ; and the size, mode 

 of growth, and foliage are all very similar. But the flowers are smaller, 

 and the middle lobe of the column shorter and crenulate. 



XCI. Cyperaceae. 

 Kyllinga brevifolia Rottb. 



Abundant in swamps on the seaward side of the cliffs to the north of 

 the Manukau Harbour ; T. F. C. In this locality it is certainly a recent 

 introduction ; nor am I aware that it has been previously collected in New 

 Zealand outside the North Cape peninsula. But its nativity in any part of 

 New Zealand must be regarded as exceedinglv doubtful. 



Carpha alpina R. Br. 



Mr. P. G. Morgmt sends me a highly depauperated state from the 



summit of Mount Frederic, north of the Buller Valley ; alt. 3,500 ft It 



forms small dense patches barely more than an inch in height, and the 

 inflorescence is reduced to one or two spikelets. 



XCII. Gramineae. 



Ehrharta Colensoi Hook. f. 



Griffin Range, western Southern Alps ; alt. 4,500-4,900 ft. ; P. G, 

 Morgan ! 



Microlaena polynoda Hook. f. 



In great abundance on the site of the old Maori pa Te Korekore, near 

 Muriwai, about twenty-five miles north of the Manukau Heads ; T. F. C. 

 This is the only locality I am acquainted with in the Auckland District. 



XCIII. Filices. 



Asplenium japonicum Thunb. 



Banks of the Waiaruhia River, a tributary of the Waitangi, Bay of 

 Islands County T. H. Trevor ! This locality is some distance to the south 

 of the Okura River, where it was first discovered by Miss Clarke. (See 

 Trans. N.Z. Inst., vol. 22, p. 448.)
