NOTES ON SOME PLANTS OF OTAGO, NEW ZEALAND. 323 
5. E. rotundifolium, Forst. Banks of the stream, Abbott's creek, 
Greenisland, 5—6 in. high; November, in flower, W. L. L. Stems 
under 6 in. high, EUPEN but puberulence only well-marked supe- 
riorly (on young shoots). Leaves glabrous on both surfaces, sometimes 
with traces of puberulence. Central leaves (about centre of stem), as 
usual in the Otago Epilodia, larger than upper and lower ones. Longest 
leaves about 4 in. long, and somewhat less in breadth. Outline of 
leaf sometimes suborbicular. Margin sinuate-serrate ; teeth sharper 
than in the other Otago species above mentioned ; but unequally or ir- 
regularly so, as is also usual in the New Zealand Epilobia. Leaves 
opposite, so shortly petioled as to become sometimes, in the upper 
and lower parts of the plant, subsessile. I have never seen the leaves 
uniform in size and form throughout the plant. Flower whitish. 
Though I did not myself meet with others, I believe there are few of 
the 17 New Zealand species of Zpilobium that do not occur in Otago. 
Genus II. HYPERICUM. 
There are only two New Zealand species, both of which occur in 
Otago. These species are counected by passage-forms, and the remarks 
which I have had occasion elsewhere* to make regarding the problem 
of unity or plurality of species in certain genera of Otago plants are 
very applicable here. I am disposed to consider H. Japonicum as 
merely a dwarf, straggling, procumbent, slender condition of H. gra- 
mineum. 
1. H. gramineum, Forst. Chain Hill ranges, common; Uplands 
around Stoneyhill ; December, in flower, W. L. L. Generally 6-8 in. 
high, growing in tufts. Resembles in general aspect the British H. 
linarüfolium, Vahl. My specimens have as great a tendency to pro- 
cumbency as Japonicum. Branches about 6 in. high: 4-angled character 
not always distinct. Leaf oblong-lanceolate, with revolute margin ; 
generally under $ in. long, and $-$ in. broad. Frequently acquires in 
drying various shades of buff or brown. Flowers 2 or 3; peduncles 
subdivided (branching secondarily) or simple. Sepals in herbarium 
assume the orange-red tint of the corolla. 
2. H. Japonicum, Thunb. Ranges about Finegand, Lower Clutha, 
abundant; December, in flower, W. L. L. Generally 3-4 in. high,
