Polypodium grammitidis, Br. 
On the West Coast of the South Island this plant exhibits a greater 
range of variation than usual. Mature sporiferous specimens collected by 
Mr. J. D. Enys are from 2 to 3 inches long, and not more than 4 inch 
wide. The lower portion is cut into deltoid pinnules or lobes } of an inch 
long; the upper part is deeply toothed. In this state it closely resembles 
the Cingalese P. eucullatum, Nees, but the pinnules are broader at the base. 
Some of Mr. Hamilton's Okarito specimens have the pinnules lobed and 
Worked to an excessive degree, in others the fronds are 8 to 10 inches long, 
pinuatifid, with simple entire piunules. In others again the frond is 
similar, but the pinnules are slightly toothed. When in this state I am 
unable to distinguish this plant from P. subfalcatum, Blume, of the Malay 
Archipelago. 
Lycopodium ramulosum, Blume. 
Only known at present from this locality, and the vicinity of Hokitika. 
See Art. LXXIII. 
P.S.—Since the above was written, Mr. Hamilton has informed me that 
Celmisia bellidioides and Euphrasia revoluta were collected near the face of 
the glacier, at an clevation of between 700 and 800 fect,

the Hauraki Gulf. By T. Kırg, F.L.S.

Ix few localities is the importance of atmospheric moisture, as a factor in 
the distribution of vegetable life, more forcibly demonstrated than amongst 
the small islands in the lower part of the Hauraki Gulf. Most of these 
islands consist of sandstones, clays, and slates, and are watered by springs 
and small streams. In every case the islands of this class exhibit a luxu- 
riant vegetation, more or less copious in the number of species, according 
to the variety of soil, situation, and aspect. One or two of the smaller 
islands are composed of basaltic scoria, and are entirely destitute of water, 
except such as may be collected in rock-cavities during rainy weather, 
and are therefore entirely dependent upon atmospheric moisture for the 
maintenance of vegetable life. While both classes exhibit marked pecu- 
liarities in their botanical features, the most striking are those to be seen on 
islands of the latter class, destitute alike of surface soil and a perennial 
water supply,
