Bracelet Honey Myrtle

Melaleuca armillaris (Sol ex Gaertner) Smith

Family: - Myrtaceae


Bracelet Honey Myrtle is so named because the flowers are wrapped around the stem like a bracelet with leaves above and below the inflorescence. Myrtle refers to its membership of the Myrtaceae family.


Bracelet Honey Myrtle is a large, perennial, evergreen shrub to 5 m high with hard or corky bark. The leaves are alternate, somewhat leathery, linear, more or less flat, 12-25 mm long and 1 mm wide. The white (rarely pink) flowers are densely clustered into cylindric spikes 30-70 mm long. The individual flowers each have 5 small petals above a cup-shaped leathery base. The stamens are fused into 5 bundles, each bundle comprising 16-18 stamens. The fruits are closely clustered with each fruit 3-5 mm across and opening by 3 valves to release the tiny seeds.

It is native to eastern Australia and commonly grown in WA gardens but now considered a potential environmental weed. It flowers mainly in spring and summer.

White or rarely pink.

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, persistent.

Petals - 5, free and overlapping, short egg shaped, 3-5 mm long,

Stamens - 16-18 per bundle, longer than petals, joined in 5 bundles opposite the petals. Claw 5-6 mm long.

Anthers - Versatile, not erect, 2 parallel cells, release pollen through lengthwise slit.


Dry, woody, shortly cylindrical capsule, 3-5 mm diameter with no stalk. Orifice 2-4 mm diameter. 3 valved. Seed released through slits at the top (midway between partitions) when ripe.

5 Sepals, free, connected to the floral tube.

5 Petals free.

Ovary inferior or half inferior.

Ovules few to many per cell.

Stamens in 5 bundles opposite the petals, longer than the petals

Life cycle:




By seed.

May regrow from the stump if damaged.

Flowering times:

Summer in NSW.

Seed Biology and Germination:

Vegetative Propagules:

May regrow from stump.




Population Dynamics and Dispersal:

Spread by seed. Many will coppice when the stem is cut.

Tend to hold their seed in the canopy.

Origin and History:

Native to eastern Australia.

Often on headlands and coastal ranges.


Temperate. Mediterranean.


Plant Associations:

Heath communities.



Ornamental, gums, fuel, shelter.


Not recorded as being naturalised in WA but of concern to local environmental groups.

Weedy and naturalised in parts of Victoria.


Not recorded as toxic.


Management and Control:

Manual removal is usually effective.

As Bracelet Honey Myrtle has not yet been confirmed as naturalised in WA, confirmation of its identity should be obtained before destroying plants.


Eradication strategies:

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 neat glyphosate(450g/L) or a mix of 1 part Access in 60 parts diesel.

Small trees can be spray overall until just wet with a mix of 100 mL glyphosate(450g/L) plus 1 g metsulfuron(600g/kg) plus 25 mL Pulse® in 10 L water. Triclopyr and triclopyr plus picloram mixes are also effective.

Mechanical removal is also effective.

Herbicide resistance:

None reported.

Biological Control:

Unlikely because it is an Australian native species.
