3. Pape 31.:7 Soil. 
Since the brief account of the soils was written, through the investigations 
of AsTONn, a good deal is now known regarding their chemical composition. 
From the published results of the above investigator, together with some other 
soil analyses, Wiırp, in “Soils and Manures in New Zealand” (1919), has com- 
- piled a useful summ 
A distinction BR be drawn between soils originating from greywacke 
and those from mica-schist. The latter are especially fertile and contain, when 
apparently dry, a considerable amount of available moisture. They occupy 
a wide area in the North and South Otago botanical districts. 
There are many areas of soil derived from limestone in most of the 
mainland botanical districts, but the fact of a soil ERDE limestone by no 
means ‚proves that it is dit calcareous.- 
2. Pages 73—74. Dune vegetation. 
The dune Geranium is not, as stated, p. 76, G. sessiliflorum var. glabrum, 
but a more robust plant which is apparently confined to dunes, or their im- 
mediate neighbourhood. 
On certain dunes in the Sue of Wellington, (Lyall Bay der Acaena 
novae-zelandiae var. pallida is a striking feature. It forms pale, yellowish-green 
mats on the sand, ı sq.m, or more, in size and behaves like a true "sand- 
binder”, in its extremely stout, more or less woody stems greatly lengthening 3 
when Batieid by drifting sand. Floristically, this plant bears a much greater 
resemblance to some- of the Australian varieties of A. Sanguisorbae than it 
does to any of its New Zealand allies.
