Description
Melaleuca sphaerodendra is shrub or small tree growing to a height of 10 m (30 ft) with its branchlets densely covered with hairs. The leaves are 7–19 mm (0.3–0.7 in) long, 2–5 mm (0.08–0.2 in) wide, narrow oval to egg-shaped, rounded at the end and have 3 to 5 parallel veins. When young, the leaves are covered with hairs similar to those on the branchlets but become glabrous as they mature.
The flowers are white or cream and occur on the ends of the branches which continue to grow after flowering. The petals are 1–2.2 mm (0.04–0.09 in) long and the stamens are arranged in five bundles around the flower, with 2 or 3 stamens per bundle. Flowering occurs mainly from July and September and is followed by the fruit which are woody capsules 2.2 mm (0.09 in) long.
Taxonomy and naming
Callistemon gnidioides was first formallydescribed in 1934 by André Guillaumin, then transferred to the genus Melaleuca as Melaleuca sphaerodendra in 1998 by Lyndley Craven and J.W. Dawson in the journal Adansonia. The specific epithet (sphaerodendra) is from the Ancient Greek σφαῖρα (sphaîra) meaning “ball" or "globe" and δένδρον (déndron) meaning “tree” referring to the roughly spherical crown of the tree. There are two varieties of this species:
