Hymenanthera
HYMENANTHERA CRASSIFOLIA.--A curious New Zealand shrub with rigid
ashy-coloured branches, and small leathery leaves. The flowers are
violet-like in colour, but by no means conspicuous. The small white
berries which succeed the flowers are, in autumn, particularly
attractive, and very ornamental. It is perfectly hardy and of free
growth in light peaty earth.
