NOTES ON SOME PLANTS OF OTAGO, NEW ZEALAND. 325
of leaf (under surface) very slight and witli difficulty distinguishable,
unless uuder the lens ; best noticed on the young flower-panicles
(flower-pedicels and calyx). Leaf generally 2 in. long and f in. broad,
more or less broadly ovate, sometimes lanceolate or broadly obovate or
obcordate, usually acuminate or mucrouate, 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.
2. P. rosea, Raoul (P. capstilaris, Fl. N. Z.). East Taeri bush,
climbing on Ruhns amlralis ; Christie's Bush, Saddlehill ; November,
in flower, W. L. L. In the climbing form on Rubus australis, the
stem is slender, twining, finely puberulent, the hairs being yellowish
and very fine, as in albiflora. Leaves linear or linear-lanceolate, but as
coriaceous as in albiflora, 2-2\ in. long and \ in. broad, broadest at
the roundish turgid base, tapering gradually to a point. Margin iiTe-
gularly sinuate. Upper leaves nearly entire, lanceolate ; all leaves very
shortly petioled.
In 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 albiflora. Leaves vary
greatly in a single specimen, much larger and narrower than in the
climbing forms 3|—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 albiflora, drying to the same colour; sometimes twist on
themselves like the branchlets.
Genus IV. PlMELEA.
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
;
