Family: - Myrtaceae
Evergreen small trees or shrubs often called Paperbarks. They usually have leathery leaves.
Stipules - None or tiny.
Blade - Simple, dotted with oil glands, smooth edges, often leathery.
Stems:Often with papery bark.
Flower head:Usually a head or spike with the axis growing out during or after flowering.
1-3 flowers within each bract or floral leaf.
Bracts usually scale like, overlapping and fall of with age
Flowers:Radially symmetrical. Stalkless. Floral tube is cup shaped.
Ovary - Inferior or almost so.3 celled with few-many ovules per cell. Top is convex, almost always hairy, with a central depression around the style
Style - Simple, terminal, threadlike.
Stigma - Often very small.
Sepals - Connected to the floral tube. 5 free, small, usually fall off in fruit.
Petals - Usually 5, free and overlapping, short, clawed or narrowed at the base, broad near the top.
Stamens - 15 to many, longer than petals, joined in 5 bundles opposite the petals.
Anthers - Versatile, not erect, 2 parallel cells, release pollen through lengthwise slit.
Fruit:Dry, woody capsule with no stalk. 3 valved. Seed released through slits at the top (midway between partitions) when ripe.
Seeds:Tiny, usually many.
Roots:Taproot with many laterals.
Key Characters:Trees or shrubs
Leaves with aromatic oils.
Flowers actinomorphic (radially symmetrical)
Floral tube well developed.
5 Sepals, free, connected to the floral tube.
4-6 Petals free.
Ovary inferior or half inferior.
Ovules few to many per cell.
Stamens in 5 bundles opposite the petals, longer than the petals
Anthers not erect, versatile.
Fruit dehiscent, 3 valved capsule.
Adapted from B.L. Rye.
May regrow from stump if damaged.
Flowering times:Seed Biology and Germination:
May regrow from stump.
Allelopathy:Population Dynamics and Dispersal:
Spread by seed. Many will coppice when the stem is cut.
They tend to hold their seed in the canopy.
Origin and History:Mainly Australian natives.
Distribution:ACT, NSW, NT, QLD, SA, TAS, VIC, WA.
Ornamental, gums, shelter, medicinal, fuel.
Detrimental:Some species are weedy and invasive.
Toxicity:Not recorded as toxic.
Legislation:The Wildlife Conservation Act protects this species in the wild.
Management and Control:Manual removal is usually effective.
Burning followed by bull dosing or chaining is usually the most cost effective for large stands.
Individual trees can be sawn off close to ground level and the stump painted immediately with Access. Saplings can be sprayed overall with Garlon, Grazon or glyphosate.
Herbicide resistance:None reported.
Biological Control:Unlikely because it is an Australian native species.
