Telopea mongaensis, commonly known as the Monga Waratah or Braidwood Waratah, is a shrub or small tree in the Proteaceae
Proteaceae
Proteaceae is a family of flowering plants distributed in the Southern Hemisphere. The family comprises about 80 genera with about 1600 species. Together with the Platanaceae and Nelumbonaceae they make up the order Proteales. Well known genera include Protea, Banksia, Embothrium, Grevillea,...

Description

Telopea mongaensis grows as a tall shrub to 6 m (20 ft) high. The thin leaves are 4–18 cm (1.6–7 in) in length, and 0.5–2 cm (0.2–0.8 in) wide. The red flowers form in spring. Open, thin and wiry, the flowerheads (inflorescences) are not as spectacular as those of T. speciosissima but are much more numerous on the plant. Each flowerhead is around 6 to 10 cm (2.4-4 in) in diameter, and composed of anywhere from 28 to 65 individual small flowers, or florets. Anthesis, or the opening of the flowers, begins at the edges or base of the flowerhead and moves to the centre. The individual flower bears a sessile anther (that is, it lacks a filament), which lies next to the stigma at the end of the style. The ovary lies at the base of the style and atop a stalk known as the gynophore

, and it is from here that the seed pods then develop. Meanwhile, a crescent shaped nectary lies at the base of the gynophore. The flowerheads are surrounded by green or pink leafy bracts 1.2-4.5 cm (0.5-0.9 in) in length, much less prominent than those of the New South Wales Waratah. Flowering is followed by the development of woody seed pods, 4.5–7 cm (0.9-2.8 in) long.

It can be distinguished from the similar T. oreades, which has larger leaves and often grows with a tree-like habit.

Taxonomy

Edwin Cheel was an Australian botanist and collector.Before being appointed as a staff member of Centennial Park in 1897 he was a gardener in New South Wales and Queensland. Later he transferred to the Royal Botanic Gardens, Sydney. In 1908 he joined the National Herbarium, and was appointed Chief...

Cultivation

Telopea mongaensis is more tolerant of shade, heavier soils and cooler climates than its more showy relative. It grows as a more compact plant of around 2 m (7 ft) in height in full sun. It is frost tolerant and has been grown in southern England, and has been awarded an Award of Merit by the Royal Horticultural Society
