The plant forms large matted patches on the ground. Stems 2’ to 6" 
long, branched, densely tufted and matted together. Leaves distant or close 
set and imbricate, appressed, petiole membraneous, broadly sheathing, blade 
expanded and deeply cut into from 5 to 7 subacute one-nerved segments, 
less than }’ long. 
My cursory examination of Professor Scott’s specimens did not enable 
me to detect flowers or fruit, but in ‘Flora Antarctica’’ the umbels are 
described as terminal, 3-flowered. Calyx teeth acute. Fruit ovate, termin- 
ated by elongated styles, mericarps convex on the back, contracted towards 
the suture. 
Pozoa reniforme, Hook. f. 
I found this species growing plentifully on a moraine close to the snow- 
line in a deep valley of the Spenser Mountains, Amuri. Previously it was 
only known from the Auckland Islands. 
Cotula integrifolia, Hook. f. 
This plant is not uncommon in situations where water has stagnated but 
which have become dry on the approach of summer. It varies greatly in 
stature and luxuriance, but a complete series may be traced from minute, 
one-flowered forms with entire leaves, the plant less than 1 inch in height, 
to the most luxuriant form of C. coronopifolia. It can only be regarded as 
a transitory state of that species and is unworthy to take rank even asa 
trivial variety. 
Mentha australis, Br. 
This species remarkable even amongst its congeners for its powerful 
odour occurs in great abundance in the Wairarapa, especially at Carterton, 
but I fear that it must be regarded as an introduced plant. I observed it 
at intervals for three or four miles along the road, especially plentiful in 
ditches but occurring also in the adjacent forest. 
It is an erect herb with pale green leaves and acutely angled stems ; the 
"flowers are produced in great abundanee in axillary false whorls which may 
be pedicellate or sessile ; the calyx is pubescent or hairy with long subulate 
teeth, the corolla tube is small, scarcely exceeding the calyx in length, and — 
the mouth is deeply two-lobed. : 
Our plant fills the ditches by the road-side, where it attains the height of 
over 2 feet. In moist places in the forest it is much smaller. It is called
