var. $f he ot most widel¥ "distributed species in New Zealand. Its nearest ally is 
A. Cockaynei, from which it cannot be separated by any strict line of demarcation. 
Ordinarily, however, A. Cockaynei can be distinguished by the smaller size and much 
more rigid leaves, which are usually silky on both surfaces, and occasionally even 
villous. In foliage A. nervosa approaches A. trinervia, but from that plant, and from 
all the large-leaved species, it is at once removed by the fruiting-perianth being enlarged 
and coloured within. 
8. A. Cockaynei Cheesem. n. comb.—Very closely allied to A. nervosa, 
and possibly only a subalpine state, but smaller in all its parts, and with 
the fohage much more rigid and silky. Leaves numerous, 2ft. 6in. long 
or more, 13-l131n. broad, linear or linear-ensiform, gradually narrowed 
into long acuminate points, dilated at the sheathing base; midrib stout, 
prominent beneath; half-way between the midrib and the margin is a 
stout rib composed of 2 almost coalescent veins; ribs often coloured red 
or purplish-red ; upper surface of leaf usually with a thin easily detached 
silvery pellicle, and generally more or less clothed with silky appressed 
hairs, sometimes almost villous; under-surface paler, more or less scurty, 
generally covered with white appressed scales or hairs, which are most 
plentiful along the margins; veins numerous, evident; sheathing base 
of leaves densely covered with long appressed silvery-white or tawny hairs. 
Flowers very similar to those of A. nervosa, but the panicles much smaller 
and with fewer branches, and the females much more compact. Berry 
ovoid or ovoid-globose, pointed at the tip, 4in. diam., fleshy, reddish- 
orange, enclosed in the persistent cup-shaped enlarged base of the perianth, 
which is often but not invariably coloured red within. Seeds 2-3 in each 
cell, black, angled——A. nervosa var. montana 7’. Kirk in Cheesem. Man. 
N.Z. Fl, (1906) 714. A. montana Cockayne in Bot. Survey Tongariro

NortH AND Sout Istanps, Stewart Istanp: Abundant in subalpine localities 
fee Hikurangi, Mount Egmont, and Taupo southwards. 2500-5000 ft. December- 
anuary. 
There can be no doubt that a direct passage can be traced from A. Cockaynei into 
A. nervosa. On the mountains of north-west Nelson I have several times satisfied 
myself on this point, and Mr. Petrie has come to the same conclusion as regards the 
Tararua Mountains (Trans. N.Z. Inst. xl (1908) 293-94). But the difference between 
the extreme state of A. Cockaynei, with its low tufts of greyish-white foliage shaggy 
from the abundance of silky hairs, and the highly developed form of A. nervosa formerly 
known as A. grandis, in which the leaves are almost glabrous, and frequently reach a 
height of 8 ft., with a width of over 4in., is so pronounced that I cannot refuse to 
separate the two plants. 
9- A. Petriei Cockayne in Trans. N.Z. Inst. xxxi (1899) 419.—Densely 
tufted, forming large patches in damp alpine meadows. Leaves 9-30 in. 
long, 3-15 1in. broad, linear-ensiform or linear-subulate, gradually narrowed 
into a long acuminate point, expanded at the sheathing base, rigid and
