136 * GRISELINIACEAE [1]

Matthew L Baker [2]

Evergreen, dioecious shrubs or small trees, sometimes climbing or epiphytic (not in Tas.). Leaves alternate or sub-opposite (not in Tas.), stipules absent. Inflorescences racemose to paniculate. Male flowers actinomorphic, 5-merous; petals free; stamens 5, attached to a glandular disc located at the centre of the flower, anthers 2-locular, dehiscence by longitudinal slits. Female flowers actinomorphic, 5-merous; sepals sometimes absent or soon caducous; petals sometimes absent, caducous; carpels 3, 2-locular; ovary inferior, styles 3. Fruit drupaceous, 1-seeded.

A monogereric family (see generic account for species and distributional data). Griselinia has been placed in Cornaceae but is now considered to be in its own monogeneric family. Griseliniaceae are placed in the Apiales though it is taxonomically isolated (see Chandler & Plunkett 2004).

Description as per family.

A genus of 7 species in New Zealand (2 spp.) and South America (5 spp.; Chile, Argentina & Brazil). 1 species introduced in Australia and naturalized only in Tasmania. Several members of the genus are cultivated in Australia as ornamentals.

Large shrubs to medium trees to 17 m tall; young stems golden-yellow to olive-green, becoming grey-brown with age. Leaves simple, alternate, glabrous; petioles 8–35(–40) mm long, partially sheathing the stem; lamina leathery, elliptic to orbicular or ovate, 30–90(–133) mm long, 20–65(–13) mm wide, base oblique to equal, adaxial surface glossy green, abaxial surface less glossy and pale yellow-green, margin entire, revolute, apex rounded to obtuse, occasionally emarginate. Male inflorescences paniculate, to 50 mm long. Male flowers small on pedicels to 2 mm long; sepal, minute; petals c. 1 mm long; stamens less than 1 mm long. Female inflorescences 2 of 2paniculate or racemose, to 70(–100) mm long. Female flowers on pedicels to 7 mm long; sepals and petals as per male flowers; styles 3. Fruit obovoid, c. 6 mm long, c. 4 mm wide, green at first, maturing black. Flowering Oct.-Dec.; fruiting Dec.-Aug.

Tas. (TWE); native of New Zealand. Introduced to Tasmania as an ornamental plant and naturalized only in Strahan but recorded elsewhere as a plant of cultivation (e.g. Hobart). Griselinia littoralis superficially resembles Coprosma repens A.Rich. (Rubiaceae), both species have leathery leaves with a glossy adaxial leaf surface. However, the two species can easily be distinguished by their leaf arrangement: Coprosma repens has opposite leaves whereas G. littoralis has alternate leaves. Griselinia littoralis was first recorded in Tasmania in 2005 (Baker 2007). Plant height, inflorescence length, fruit characteristics and phenology in the above description are taken from Dillon & Muñoz-Schick (1993).
