stout petiole, remotely and obscurely sinuate-serrate, excessively thick and 
coriaceous, midrib and margins thickened. Leaves of mature trees 2—4 in. 
long, 4}-2in. wide, linear or linear-lanceolate, obtuse or acute, obscurely 
serrate, very thick and coriaceous, midrib and margins thickened ; petiole 
short, 4-4in. long, jointed on to the branch. Flowers small, dioecious. 
Umbels usually terminal, but occasionally axillary as well, compound, shorter 
than the leaves; rays 3-7, bracteolate. Ovary 3-5-celled; styles the 
same number as the cells, connate at the base, free and recurved at the 
tips. Fruit broadly ovoid, 3-5-celled and -seeded.—Panax lineare Hook.

SoutH Istanp: Subalpine forests from Collingwood to Preservation Inlet, chiefly 
on the western side of the Southern Alps. Altitudinal range usually between 2500 
and 4500 ft., but descends to low levels in the sounds of the south-west coast of Otago. 
January—February. 
The foliage of the young seedling is very narrow-linear, from 2-3 in, long, with a 
breadth of about }in. As the plant increases in size, the leaves also increase in length, 
so that a young tree 4 or 5 ft. high frequently has leaves 10 in. long by Lin. wide. In 
older stages the leaves gradually become shorter, so that in flowering examples they 
are often less than 2 in. long, with a breadth of $in. to in. The leaf-change through 
which the species passes is thus somewhat similar to that of Pseudopanax crassifolium $ 
but is not so conspicuous, and the leaves of the young plant are never deflexed,

2. N. simplex Beem. mm Journ. Bot. iv (1866) 296.—A shrub or small 
tree 8-25 it. high, everywhere smooth and glabrous. Leaves of mature 
trees 1-foliolate, variable in size, 2-5 in. long, lanceolate or oblong- or obovate- 
lanceolate, coriaceous and glossy, acute or acuminate, rarely obtuse, sharply 
serrate or nearly entire; petiole 1-3in. ‘long, jointed at the top. Leaves 
of young plants differing greatly at various periods of growth or in various 
localities ; of young seedlings ovate or broadly ovate, coarsely serrate or 
lobed. These are either followed by 3-5-foliolate leaves with the leaflets 
long and narrow and deeply cut or almost pinnatifid, or pass into 3-folio- 
late leaves with the leaflets broader and often variously lobed. Finally, 
the leaflets become narrower, the serratures less prominent, and the lateral 
leaflets disappear, the plant thus assuming its mature foliage. Umbels 
small, shorter than the leaves, axillary or terminal, irregularly compound ; 
secondary umbels 8-16-flowered, the terminal one usually female, the lateral 
male. Flowers small, greenish-white. Ovary 2-celled; styles 2, free to 
the base, recurved. Fruit din. diam., orbicular, compressed ; seeds 2.—

The remarkable series of changes through which the foliage of the young plants 
passes is well worth careful study.
