common on the Hanmer Plain. In this case, as the species is small 
and easily overlooked, it may be expected to occur in the inter- 
mediate area between the above two localities. Lycopodiwm cernwum, 
a fine club-moss, with spores easily carried by wind, is extremely 
common in the North and South Auckland and the northern part of 
the Volcanic Plateau Districts, but from near Lake Taupo it does 
not occur again until near the West Wanganui Inlet (North-western 
Botanical District), where is was discovered last year (1918) by 
Mr. B. C. Aston. Though the spores of lycopods are so easily dis- 
tributed by the wind, their germination is not such a common 
happening, by any means; it seems possible in this case, then, 
that wind-borne spores are accountable for this southern station of 
the plant, and that it is a chance comer. The Chatham matipo 
(Suttonia chathamica), common in the Chathams, also occurs at one 
or two places, but not abundantly, on the east coast of Stewart 
Island. The Australian Lewcopogon Richei is common on dry ridges 
in the Chatham Islands, but elsewhere in New Zealand it is known 
only at a locality not far from the North Cape. A large nettle, 
Urtica australis, common in Chatham, Lord Auckland, and Anti- 
podes Islands, is known elsewhere only on certain small islands in 
Foveaux Strait. 
The following species are known in only one locality, and, it 
may be, in only the one station: The small Australian club-moss, 
Lycopodium Drummondii, has been noted on only a few square 
yards of boggy ground near Kaitaia, northern Auckland. The bog- 
anise (Angelica trifoliata) has been noted at only two stations, not 
far apart, on the Mount Torlesse Range, Canterbury. Coprosma 
Buchanani is confined to a few stations, not far distant from one 
another, on the shores of Cook Strait (Wellington). Certain species 
already cited in this chapter are confined to the North Cape Pro- 
montory. A well-marked variety of Veronica elliptica is confined to 
Titahi Bay, Wellington. Veronica loganioides is known only from the 
vicinity of Mount Potts (Canterbury). Veronica Astoni is known 
only on the Tararua Mountains, where it is fairly common. Poa 
pygmaea, already mentioned in this chapter, is confined to the summit 
of Mount Pisa (North Otago Botanical District). Raoulia rubra 
(fig. 67) is confined to the summits of the Tararua Mountains, where 
it is fairly common. Logania depressa, which has not been collected 
or seen since Colenso discovered the species more than sixty-two
