yellowish-green; the midrib is keeled on the under-surface, which latter 
is thickley tomentose with dense silky tomentum. So far as I known, 
C. pseudo-Lyallii is confined to the drier mountains of Canterbury. Pro- 
bably, too, it is one of the species which have been confused with C. 
monrot Hook. f. 
706. Rubus Barkeri Cockayne in Trans. N. Zealand Inst., 1909, XLII 
(1910), p. 326. — Fruticulus prostratus ramosissimus, ramis inermibus 
v. paulum aculeatis gracilibus elongatis radicantibus, foliis 3- raro 1- 
foliatis cire. 14 cm longis, foliolis lanceolatis circ. 3—8 cm longis basi 
truncatis v. inaequalibus serratis membranaceis, petiolis costisque parce 
aculeatis pilosisque. — New Zealand, South Island: Westland, near 
Lake Brunner, on the forest-floor. S. D. Barker! — The species is 
closely allied to Rubus parvus Buch., but differs in the trifoliate leaves 
with lanceolate leaflets and not simple linear leaves, serrate rather than 
dentate leaf-margins, non-blooming habit, and greater size in all its 
parts. — The terminal leaflet is the largest, measuring about 7,6 cm by 
2,8 cm the size of the smaller lateral ones being about 6 cm by 2,1 cm. 
The leaves are pale green on the undersurface, but above vary much 
in colour according to the season of the year and the exposure to light. 
This is most marked in autumn and winter, when the colour is bronzy 
with a lustrous sheen, or various shades of purple. Even in summer 
the coloration of the upper surface is striking. Where the light is dim 
the leaves remain green. — This beautiful leaf-coloration, the habit of 
the plant, and the ease with which it can be cultivated, make Barkers 
Rubus a quite important decorative plant, especially for rock-gardens, 
where in the future it will doubtless become a universal favourite. — 
Rubus parvus exhibits a similar coloration, but to a much lesser degree.
