Description

Meryta denhamii grows to about 6 metres (20 ft) tall. The large, stiff, leathery leaves are elongated, curved at the edges and appear in tufts or bunches at the ends of the branches. Their central rib is thick and fleshy with longitudinal grooves. On younger trees the leaves are up to 45 centimetres (18 in) long and about 12 cm (4.7 in) wide. On older trees the leaves may be up to 1 m (3.3 ft) long and 24 cm (9.4 in) wide. The flowers exude a sweet scent. The plants are either female or male. Since the anthers protrude from the flowers, it is likely that the pollen is spread mainly by wind. Female flowers also occasionally produce anthers, but these are stunted and unproductive.

Discovery

Meryta denhamii owes its discovery to Scots William Grant Milne (?–1866), a gardener at the Edinburgh Botanic Garden, who joined the HMS Herald expedition to the south-western Pacific (1852–1856) as a botanist. Milne found the tree growing on the Isle of Pines in the south of New Caledonia. Specimens were sent to the Royal Botanical Gardens in Kew where the plant flowered in the greenhouse in 1860. Two years later botanist Berthold Seeman named the plant Meryta denhamii in honour of Henry Mangles Denham, captain of Herald, for whom also the town of Denham, Western Australia was named.

Cultivation

Rare in cultivation, M. denhamii may be grown fairly easily in warm frost-free climates like those of Sydney, Australia, or Florida in the United States. A slightly hardier alternative is the New Zealand Puka tree, M. sinclairii, which has wider leaves and can withstand frosts down to −2 °C (28 °F) once established.
