Tritonia gladiolaris (Lam.) Goldblatt & J.C.Manning, syn. Tritonia lineata (Salisb.) Ker Gawl., grows in grassland in the southeastern Cape. It has creamy white or pale yellow or orange funnel shaped flowers with dark veins. This plants copes with a Mediterranean growing cycle even though it is a summer rainfall species, but I wouldn't say it thrives. When grown with regular summer water it expands rapidly. When grown with a dry summer it merely survives.

Common Names

chiffon lace, lined tritonia, montbretia, tritonia

 

Origin

Native to southern Africa (i.e. Lesotho and South Africa).

 

Cultivation

Lined tritonia (Tritonia gladiolaris) is commonly cultivated as a garden ornamental, particularly in the temperate regions of Australia.

 

Naturalised Distribution

Widely naturalised in southern and eastern Australia (i.e. in the eastern parts of central and southern New South Wales, in Victoria and Tasmania, in south-eastern South Australia and in the coastal districts of south-western Western Australia). Also rarely naturalised in the cooler sub-coastal parts of south-eastern Queensland and occasionally naturalised on Norfolk Island.

 

Also naturalised in New Zealand.

 

Habitat

A weed of grasslands, open woodlands, hillsides, roadsides, waste areas and disturbed sites in temperate regions.

 

Habit

An upright (i.e. erect) herbaceous plant usually growing 30-60 cm tall. It re-grows each year from long-lived (i.e. perennial) underground 'bulbs' (i.e. corms). These 'bulbs' (up to 2 cm across) and are covered in a tunic of brown netted fibres.

 

Distinguishing Features

an upright herbaceous plant usually growing 30-60 cm tall and re-growing each year from long-lived underground 'bulbs'.

 

its long, strap-like, leaves (7-35 cm long and 7-18 mm wide) are mostly tufted at the base of the plant.

 

its tubular flowers are borne spikes containing 5-15 flowers at the tips of the flowering stems.

 

these cream, white or pale yellow flowers have six 'petals' with prominent purple or blackish veins.

 

its oval fruit capsules (3-8 mm long) turn brown and split open when mature.

Stems and Leaves

The slender unbranched flowering stems are green and hairless (i.e. glabrous).

 

The long, strap-like (i.e. linear to lanceolate), leaves are mostly tufted at the base of the plant. These leaves (7-35 cm long and 7-18 mm wide) have entire margins, pointed tips (i.e. acuminate apices), and three to five prominent parallel veins. They are hairless (i.e. glabrous) and sheathed at the base.

 

Flowers and Fruit

The tubular flowers are borne spikes containing 5-15 stalkless (i.e. sessile) flowers. Each flower is subtended by a brownish-coloured bract (7-12 mm long) that is slightly toothed at the tip. The six 'petals' (i.e. tepals or perianth segments) are fused together at the base into a tube (10-15 mm long) with spreading lobes 15-25 mm long. These 'petals' are cream, white or pale yellow in colour with prominent purple or blackish veins. The flowers also have three stamens and a rounded ovary (about 3 mm across) topped with a style that separates into three short branches (about 4 mm long). Flowering occurs mostly during spring (i.e. in October and November).

 

The oval (i.e. ellipsoid) fruit capsules (3-8 mm long and 2-3 mm wide) turn from green to brown as they mature. When fully mature they split open to release numerous rounded or angled seeds.

 

Reproduction and Dispersal

Lined tritonia (Tritonia gladiolaris) reproduces by seed and vegetatively via its underground 'bulbs' (i.e. corms).

 

The seeds may be spread by wind and water, while the seeds and corms can also be spread in contaminated soil and dumped garden waste.
