2. ENARGEA, Banks and Sol. 
Glabrous almost suffruticose herbs. Stems slender, bialehted, 
wiry, knotted at the joints, lower joints with small membranous 
scales. Leaves alternate. sessile or nearly so, distichous, lanceo- 
late to oblong, prominently nerved. Flowers white, solitary or 2-4 
in the axils of the leaves. Perianth deciduous ; segments 6, dis- 
tinct, subequal, spreading, thin, nerveless. Stamens 6, hypogy- 
nous; filaments erect; anthers linear-oblong, basifixed, Jongitudi- 
nally dehiscent. Ovary sessile, ovoid, 3-celled; ovules 4-10 in 
each cell; style filiform; stigma terminal, capitate or obsoletely 
3-lobed. Berry subglobose, indehiscent. Seeds few, ovoid or sub- 
globose ; testa thin, appressed ; embryo short, straight; albumen 
horny. 
In addition to the New Zealand species, which appears to be the same as. 
the Fuegian and Falkland Island H. marginata, there are two others from Chili. 
I agree with the late Baron Mueller (‘‘ Victorian Naturalist,’’ December, 1886) 
in considering that Hnargea should take precedence over both Callixene and 
Luzuriaga. Hnargea was published by Gaertner from Solander’s notes in 1788, 
whereas Cailixene did not appear until 1789, and Luzuriaga in 1802. Hnargea. 
appears to have been rejected on account of an error in Gaertner’s plate, but 
that does not seem to be a sufficient reason for setting aside the name.

petiolate, 4-14 in. long, linear-oblong to oblong, mucronate, pale- 
green, rather rigid, coriaceous, longitudinally 5-7-nerved, transverse 
veinlets few. Flowers solitary, terminal or in the upper axils,

The New Zealand plant is said to differ from the South American mainly in 
the smaller flowers. This, however, is a variable character, and I have accord- 
ingly followed the ‘ Genera Plantarum ” in un iting the two species. 
3. CORDYLINE, Comm. 
Trees or shrubs; trunk long or short, sometimes almost want- 
ing. Leaves crowded at the top of the stem or its branches, more 
rarely alternate along the stem, sessile or petioled, very long, coria- 
ceous ; veins parallel, more or less oblique to the midrib. Flowers 
hermaphrodite, in terminal much-branched panicles, solitary or
