Flowering Gums

Eucalypts are iconic Australian trees.
The most readily recognisable characteristics of Eucalyptus species are the
 distinctive flowers and fruit (capsules or "gumnuts").
 Flowers have numerous fluffy stamens which may be white, cream, yellow, pink or red;
 in bud the stamens are enclosed in a cap known as an operculum
which is composed of the fused sepals or petals or both.

Eucalyptus (From Greek, ευκάλυπτος meaning "well covered") is a diverse genus of trees (and a few shrubs),
 the members of which dominate the tree flora of Australia.
 There are more than 700 species of Eucalyptus, mostly native to Australia,
 with 12 species found in adjacent parts of New Guinea and Indonesia and 1 in The Phillipines.

The term "gum tree" is derived from the habit of some eucalypt species to exude a sticky, gum-like substance from the trunk.
 This is by no means a general characteristic but "gum tree" has become a common generic term for most eucalypts.

Eucalypts are the essence of the Australian flora.
 Their range extends from sub-alpine areas to wet coastal forests, temperate woodlands and the arid inland.
