209 NOTES ON SOME PLANTS OF OTAGO, NEW ZEALAND. 
6. Genus VIOLA. 
1. F. filicaulis, Hook. f. Glen Martin, Saddlehill ; Signal Hill, 
North East valley, Dunedin: December, in flower and fruit, W. L. L. 
The Signal Hill plant is stronger than the Glen Martin one, having 
smaller, but more crowded leaves. 
Stem weak, filiform, trailing. Leaves variable, even in same indi- 
vidual : subreniform or subrhomboid, generally obtuse, all more or less 
crenate. Petioles do not exceed 3 inch long, very slender. Stipules 
very membranous, scarcely greenish, irregularly lacerate; teeth whitish, 
pellucid, tipped by small black glands, resembling the spermogonia of 
some fruticulose Lichens (e. g. Cladonia). 
2. V. Cunninghamii, Hook. f. Saddlehill, and Chain Hill ranges: 
November, in flower : W. L. L. 
1. Genus SAMOLUS. 
S. repens, Pers. On the cliffs, Springfield, Greenisland : November, 
young, W. L. L. The “ Wild Thyme,” of the Otago settler: the 
plant somewhat resembling, in habit, our common Thymus Serpyllum, L. | 
Leaf varies greatly as to length and tenuity; longest leaves arise 
from the base of the branches; the longer ones are generally more 
spathulate, the shorter more ovate or obovate. —Petiole sometimes 4-4 
inch long, sometimes so short that the leaf is subsessile. Lamina 
generally broadly spathulate ; apex acute or obtuse, about 4 inch, some- 
times 4 inch long, and 445 inch broad ; whole leaf is sometimes nearly 
1 inch long. 
8. Genus EUPHORBIA. 
E. glauca, Forst. Sand dunes about mouth of the Kaikorai. Oc- 
tober, young, W. L. L. The * Wainatua”’ of the North Island Maori 
(Colenso); a term also applied to the North Island Rhabdothamnus 
Solandri, A. Cunn.  [N. O. Gesneriacee.] 
A coarse, straggling, strong plant, whose rhizome creeps under the 
surface of the sand after the manner of that of Demoschanus and other 
New Zealand sand-sedges, sending up at intervals stout, erect stems, 
generally 1 foot tall. The glaucous character of the leaf is distinet 
only on undersides and tips : in the young leaves: and at the extremities 
or young shoots of the stems. Form of leaf variable, though mostly 
oblong-lanceolate ; size generally under 2 inches long and inch broad.
