T. Krrx.—On unrecorded Plants in New Zealand. 399 
I was under the impression that I must have overlooked it in other places 
on account of its similarity to M. australe, Sol., but on examining numerous 
localities in which that species is plentiful, I find no trace of M. equilaterale, 
which may possibly prove to be local with us, although of wide distribution 
in Australia. 
M. equilaterale does not appear to descend to the sea-level, or to grow in 
places exposed to the sea. So far as my observations extended, it was 
restricted to sheltered places nowhere below 250 feet above sea-level, and 
never mixed with M. australe, which was abundant on the exposed face of the 
rocks. 
In general appearance our plant resembles M. australe, but is distin- 
guished by the winged fruit and peduncles; the latter being twice or thrice 
as long as the leaves, which, in my specimens, are not quite so stout as 
those of M. australe. The immature fruit is never obviously warted as in 
that species. 
I append a description :— 
Stems prostrate, stout, 1-8 feet long. Leaves opposite 1'-2" long, fleshy, 
linear, triquetrous, or compressed, acute, glabrous. Flowers on long pedun- 
cles, terminating short branchlets, or axillary, peduncles twice or thrice the 
length of the leaves. Calyx tube fleshy, turbinate, $ of an inch long: lobes 
5, unequal, two much larger than the others, fleshy, produced along the 
calyx tube and peduncle forming a prominent wing. Petals spreading, 
white or pinkish purple. Styles about 8. Fruit (immature) punctate, with 
two prominent wings.
