Current conservation status

  • Conservation status of New Zealand indigenous vascular plants, 2017

The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley.

Brief description

Fleshy shrub to 4 m tall bearing dark green thin wide leaves that are divided into 1-3 large sharp lobes and with large, purplish, ruffled flowers that have a projecting yellow centre. Leaves 10-80 cm long by 4-6 cm wide. Flowers dished, up to 50 mm wide. Fruit yellow or orange, 23-30mm long. POISONOUS.

Distribution

Indigenous. North, South, Stewart and Chatham Islands. Widespread from the Hauraki Gulf Islands and Auckland south. In the northern part of its range actively spreading northwards caused it would seem through establishment through bird dispersal of fruit from garden plantings. Also present in south eastern Australia and Tasmania. Naturalised in parts of China and Russia.

Habitat

Coastal to montane (0-400 m a.s.l.). usually in disturbed successional habitats, in shrublands, gullies, alongside riversides, on forested margins and in reverting pasture. Often appears following fires. A common urban weed in many parts of the country.

Features

Erect to spreading, glabrous, soft-wooded shrub up to 4 x 3 m. Stems initially somewhat fleshy, purple-green, dark green to dark purple coloured, maturing with fine, firm, grey chartaceous bark, rather brittle. Leaves in stout petioles up to 50 mm long; lamina 100-800 x 40-60 mm, sometimes even larger, very dark green to purple-green, entire or pinnatisect, (then with 1-4(-6) pairs of lobes almost cut to midrib) on the same plant; lobes up to 50 x 20 mm, lanceolate to linear-lanceolate, or more or less elliptic; base decurrent on petiole; apex obtuse to acuminate. Flowers in 2-10-many-flowered cymes, peduncles up to 20 mm long at anthesis, decurved, slender but robust; pedicels pendent at fruiting. Calyx 5-8 mm long, accrescent; lobes broadly ovate-triangular, mucronate, much < tube. Corolla 50 mm diameter, rotate, violet or white, lobes very broad, margins frilled or ruffled, apices emarginate. Anthers 3-4 mm long. Berry 23-30 mm long, yellow or orange when ripe, fleshy, ovoid, ellipsoid, pendent, stone cells obvious and frequent similar in shape to seeds. Seeds 2.2-2.5 mm diameter, obovoid though somewhat asymmetric.

Similar taxa

Often confused with the now much less common S. aviculare G.Forst., which, in its typical state, has narrower leaves which are less frequently pinnatifid, usually much narrower. Flowers 10-40 mm diameter with campanulate-rotate flowers with narrower acute tipped lobes, not distinctly frilled (ruffled), smaller seeds (1-2 mm cf 2-3 mm) and a different chromosome number (2n = 46 cf 2n = 92). S. lacinatum differs from S. aviculare f. latifolium (G.T.S.Baylis) G.T.S.Baylis by its broader, wider lobes with frilled/ruffled margins and an emarginate apex, and by the chromosome number (2n = 92 cf 2n = 46).

Flowering

Flower colours

Violet/Purple, White

Fruiting

Throughout the year

Propagation technique

Easily grown from fresh seed and semi-hardwood cuttings. Tolerant of heavy shade and full sun, and dry or wet soils and cold tolerant. Extremely fast-growing and can become invasive. It should also be noted that, as with all poroporo, the green fruits are extremely toxic.

Etymology

solanum: Derivation uncertain - possibly from the Latin word sol, meaning “sun,” referring to its status as a plant of the sun. Another possibility is that the root was solare, meaning “to soothe,” or solamen, meaning “a comfort,” which would refer to the soothing effects of the plant upon ingestion.

Cultural Use/Importance

because the fruits of this species and S. aviculare G.Forst. var. aviculare yield important steroid precursors, both are widely and commericially grown, especially in eastern Europe, Russia and China.

Poisonous plant

As with Solanum aviculare var. aviculare, the yellow or green berries are poisonous but when ripe (orange) they lose much of their toxicity. The symptoms are often delayed up to 6-12 hours and may include a fever, sweating, nausea and abdominal pain. Click on this link for more information about Poisonous native plants.
