Schinus molle var. areira

Scientific Name

Schinus molle L. var areira (L.) DC.

Synonyms

Schinus molle L.
Schinus areira L.

Family

Anacardiaceae

Common Names

California peppertree, Californian pepper tree, Californian peppertree, pepper tree, peppercorn, peppercorn tree, pepperina, pepper-tree, peppertree, Peruvian mastic, Peruvian mastic tree, Peruvian mastictree, Peruvian pepper tree, Peruvian peppertree

Origin

Native to South America (i.e. Brazil, Bolivia, Ecuador, Peru, Argentina, northern Chile, Paraguay and Uruguay).

Cultivation

This introduced species is widely grown as a garden and street tree (i.e. ornamental) in Australia.

Naturalised Distribution

Widely naturalised in southern and eastern Australia. Common and widespread in eastern New South Wales, Victoria, south-eastern South Australia and southern Western Australia. Also occasionally naturalised in south-eastern and central Queensland, in other parts of South Australia and in the southern parts of the Northern Territory.

Naturalised overseas in tropical and southern Africa, temperate Asia, New Zealand, southern USA (i.e. California, Texas and Florida) and on some Pacific islands (i.e. Hawaii and the Galapagos Island).

Habitat

A weed of waterways (i.e. riparian areas), open woodlands, grasslands, roadsides, waste areas, disturbed sites and coastal environs in temperate and semi-arid regions. Occasionally also found in some habitats in sub-tropical and arid regions.

Habit

An upright (i.e. erect) tree growing up to 10 m tall, with drooping younger branches.

Distinguishing Features

Stems and Leaves

The alternately arranged leaves (12-25 cm long) are borne on stalks (i.e. petioles) 2-5 cm long. They are once-compound (i.e. pinnate) and have numerous (17-35) leaflets. Each leaflet is elongated in shape (i.e. lanceolate or linear) and is either stalkless (i.e. sessile) or borne on a very short stalk (i.e. petiolule) 0-1 mm long. These leaflets (15-50 mm long and 2-10 mm wide) are mostly hairless (i.e. glabrous) with entire margins and pointed tips (i.e. acute apices).

Flowers and Fruit

The small white flowers are arranged in drooping branched clusters (i.e. panicles). Each flower is borne on a short stalk (i.e. pedicel) 1-2 mm long and has five tiny sepals (about 1 mm long) and five small petals (about 2 mm long). Separate male and female flowers are present in these clusters. The male flowers have ten stamens, while the female flowers have reduced stamens (i.e. staminodes) and an ovary topped with a style and stigma.

The fruit resemble small berries (i.e. they are drupes) and turn from green to red or bluish-pink in colour as they mature. They are rounded (i.e. globose) in shape, 3-6 mm across, and the skin becomes papery when fully mature.

Reproduction and Dispersal

This species reproduces mainly by seed, but also spreads vegetatively by suckering.

The seeds are dispersed by birds and other animals that eat the fruit.

Environmental Impact

Pepper tree (Schinus molle var. areira) is regarded as an environmental weed in Victoria, New South Wales, South Australia and the Northern Territory. It was recently listed as a priority environmental weed in five Natural Resource Management regions.

Legislation

Not declared or considered noxious by any state government authorities.

Similar Species

Pepper tree (Schinus molle var. areira) may sometimes be confused with broad-leaved pepper tree (Schinus terebinthifolius). These two species can be distinguished by the following differences:
