NOTES ON SOME PLANTS OF OTAGO, NEW ZEALAND. 325 
of leaf (under surface) very slight and with diffieulty distinguishable, 
unless under the lens; best noticed on the young flower-panicles 
(flower-pedicels and calyx). Leaf generally 2 in. long and $ in. broad, 
more or less broadly ovate, sometimes lanceolate or broadly obovate or 
obcordate, usually acuminate or mucronate, sometimes retuse. Margin 
more or less entire, but some leaves have a very irregular sinuate 
outline: or they exhibit irregular notches, which are a tendency to 
the greater sinuosity of outline that characterizes the leaves of rosea. 
Midrib distinct on both surfaces, especially lower. Transverse veins in- 
distinct on either side and especially on upper surface. 
9. P. rosea, Raoul (P. capsularis, Fl. N. Z.). East Taeri bush, 
climbing on t australis; Christie's Bush, Saddlehill ; November, 
in flower, W. L. L. In the climbing form on Rubus e the 
stem is slender, lum finely puberulent, the hairs being yellowish 
and very fine, as in albiflora. Leaves linear or linear-lanceolate, but as 
coriaceous as in albiflora, 2-24 in. long and $ in. broad, broadest at 
the roundish turgid base, tapering gradually to a point. Margin irre- 
gularly sinuate. Upper leaves nearly entire, lanceolate ; all leaves very 
shortly petioled. 
the more shrubby form of the plant there is much branching ; 
the branches spreading irregularly, and variously twisting and doubling 
on themselves. Stem and main branches glabrous ; ultimate ramuscles 
(especially young shoots) puberulent as in a/iiffora. Leaves vary 
greatly in a single specimen, much larger and narrower than in the 
climbing forms 33-4 in. long sometimes, and $ in. broad, always 
broader at base and tapering to a point. Margin irregularly sinuate 
or notched : or sinuosity or notching is so inconspicuous that the leaf 
is almost entire; all these variations of margin occurring sometimes 
on the same branch. Margin also frequently revolute. Leaves as co- 
riaceous as in alé/flora, drying to the same colour; sometimes twist on 
themselves like the branchlets. 
enus IV. PIMELEA. 
This is one of many Otago genera (e.g. Coprosma, Gualtheria, 
Coriaria, Panax, Wahlenbergia, etc.) the book-descriptions of whose 
species I find it impossible with my limited series of specimens satis- 
factorily to follow. I have a strong conviction that certain presently 
considered species are possibly mere forms, and that a careful revision 
of such genera, with the aid of large suites of specimens, especially in
