Myrtaceae: Eucalypts, Bottlebrushes and Tea Trees

The plant family Myrtaceae contains nearly 6,000 species across more than 120 genera. More than 80 species across 23 genera can be found on campus. Myrtaceae is one of the most diverse plant families in Australia. Plants from this family are important for food, fibre and medicine for Aboriginal people. They occupy a diverse range of habitats and are fascinating in the diversity of form of leaves, fruit and flowers.

Proteaceae: Banksia, Grevillea and relatives

The Proteaceae family includes over 1600 known species. In Sydney, the main groups are Banksias, Grevilleas, Hakeas and Geebungs. The Waratah, Telopea speciosissima) is the floral emblem of NSW. Members of the Proteaceae family can be found predominantly in the southern hemisphere especially Australia and Southern Africa. Geebungs (Persoonia sp.) are one of the few genera featuring fleshy fruits. Most other genera have hard, woody capsules.

Plants in this family are usually found n low nutrient soils. They have specially adapted fine roots fro accessing limited nutrients. You can find the following species on campus, particularly in the Proteaceae section of the Earth Sciences garden.

* Banksia ericifolia - Heath Banksia
Banksia integrifolia - Coastal Banksia
* Banksia marginata - Silver Banksia
* Banksia oblongifolia – Fern-leaved Banksia

Fabaceae: Peas etc

The Fabaceae is a large family that includes three major subfamilies: Faboideae (Egg and Bacon and other native Peas), Mimosoideae (Wattles) and Caesalpinioideae (Cassia, Senna and Blackbean)

The Fabaceae is a significant family in the Sydney region. There is a broad diversity of species and they play an important part in the structure and function of various plant communities (AULD, 1996). Diversity of species is highest in vegetation on sandstone soils, particularly heath communities. Local natives on campus mostly fal into the subfamily Faboideae and Mimosoideae. Members of the subfamily Caesalpinioideae include species from northern Australian rainforests (Black Bean) and the northern hemisphere (Cassia).

Wattles (Mimosoideae) flower mostly in winter and early spring. The Peas (Faboideae) flower mostly in spring.

Most species in the Fabaceae family produce woody pods as fruit. All species are nitrogen fixers, enabling them to grow in low nutrient soils. The following trees and large shrubs can be found on campus.

Faboideae

Bossiaea heterophylla
Bossiaea obcordata
- Spiny Bossea
Castanospermum australe - Black Bean
Daviesia ulicifolia - Gorse Bitter pea
Desmodium varians - Slender Tick-trefoil
Erythrina crista-galli - Cockspur Coral Tree
Erythrina X sykesii - Coral Tree
Hardenbergia violacea - False Sarsaparilla
Indigofera australis - Australian Indigo
Platylobium formosum - Handsome Flat Pea
Pultenaea flexilis - Gracefull Bush Pea
Robinia pseudoacacia ‘Frisia’ - Golden Robinia

Caesalpinioideae

Gleditsia triacanthos ‘Sunburst’- Honey Locust
Bauhinia purpurea - Orchid Tree
Cassia fistula - Golden Rain Tree

Mimosoideae

Ericaceae: Heaths and Rhododendrons

This family includes the heaths of Europe and Australia, the Rhododendrons and Azaleas of Asia, and the Huckleberries and Blueberries of North America. Species in this family are found on tropical mountains and in the Arctic, but most commonly on poorly drained, peat soils in the temperate zone.

There is an Ericaceae garden bed in the Frank Mercer Biological Sciences garden that showcases the diversity of this plant family.

Australian members of this family usually have small tubular pink or white flowers and small hard leaves. They are pollinated mostly by bees and other insects. They provide much of the beauty of the Sydney bushland in late winter and early spring.
