CAPSELLA PROCUMBENS, Fries.—Hutchinsia procumbens, Hook. f. 
FL Tasm.—I have received specimens of this plant from Mr. 
D. Petrie, who collected them at Cape Whybrow and Forbury 
Head, Otago. Those from the last-named locality are small, 
scarcely an ineh in height; and those from Cape Whybrow do 
not attain the usual size of European and Australian specimens, 
the largest not exceeding 3 inches. The leaves are entire or 
deeply toothed in all my specimens, never pinnatifid, and the 
flowers equal the calyx. Theracemes are elongated and open in 
fruit, and the pod is narrowed at both ends. 
It will doubtless be found in other localities ; but, from its 
small size, may easily be overlooked. 
MYRIOPHYLLUM YERRUCOSUM, Lindl.—I collected this plant 
in ponds between Tauranga Harbour and the sea, but am not 
aware of its occurrence in any other part ofthe colony. It dif- 
fers from JM. elatinoides and M. variefolium in its more slender 
habit, and in having all the floral leaves pinnatifid; the flowers 
are small, with minute sepals, and the carpels are tuberculated. 
CoTULA INTEGRIFOLIA, Hook. f.—This plant is not unfrequent 
in situations where water has stagnated, but which have become 
dry on the approach of summer. İt varies greatly in stature and 
luxuriance ; but a complete series may be traced from minute 
one-flowered forms with entire leaves, the plant less thau 1 inch 
in height, to the most luxuriant forms of C. coronopifolia. It 
can only be regarded as a transitory state of that species, and 
cannot take rank even as a trivial variety. British botanists are 
familiar with a similar state of Bidens cernua. 
MENTHA AUSTRALIS, R. Br.— This species, remarkable even 
amongst its congeners for its powerful odour, occurs in great 
abundance in the Wairarapa, especially about Carterton ; but I 
fear that it must be regarded as an introduced plant. I observed 
it more or less continuously 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 abundance in axillary 
false whorls, which may be pedicellate or sessile; calyx pubes-
