Eucalyptus cosmophylla, commonly known as cup gum, bog gum or scrub gum, is a species of small tree or mallee that is endemic to South Australia. It usually has smooth bark and lance-shaped adult leaves, flower buds arranged in groups of three, white flowers and cup-shaped, cylindrical or hemispherical fruit.

Description

Eucalyptus cosmophylla is generally a multi-stemmed mallee growing to a height of Шаблон:Cvt, but sometimes a single-stemmed to Шаблон:Cvt with smooth, pale grey bark with white/pink areas and is sheds in plates. Young plants and coppice regrowth have stems that are more or less square in cross-section and juvenile leaves that have a petiole. They are elliptic at first, later egg-shaped, Шаблон:Cvt long and Шаблон:Cvt wide. Adult leaves are thick, the same dull grey-green on both sides, Шаблон:Cvt long and Шаблон:Cvt wide on a petiole Шаблон:Cvt long. The flower buds are arranged in groups of three on an unbranched peduncle Шаблон:Cvt long, the individual buds sessile or on a pedicel up to Шаблон:Cvt long. Mature buds are oval to pear-shaped, Шаблон:Cvt long and Шаблон:Cvt wide. They are green to yellow with a rounded or conical to beaked operculum usually shorter than the hypanthium. Flowering occurs between July and November and the flowers are white to cream-coloured with all anthers being fertile. The fruit is a woody, cup-shaped, cylindrical or hemispherical capsule, Шаблон:Cvt long and Шаблон:Cvt wide. The fruit generally has two ribs, a thick rim and broad valves with the tips usually just below the rim. The brown seeds are polyhedral and have narrow wings along the main edges.

Taxonomy and naming

Eucalyptus cosmophylla was first formally described in 1855 by Ferdinand von Mueller from specimens collected "on stony places in the Lofty and Bugle Ranges" and the description was published in Transactions and Proceedings of the Victorian Institute for the Advancement of Science. The specific epithet (cosmophylla) is derived from the Ancient Greek words kosmos meaning "ornament", "decoration" or "dress"Шаблон:Rp and phyllon meaning "leaf".Шаблон:Rp

Distribution and habitat

Cup gum grows near the sea in open shrubland, open forest and heath, usually in soils of low fertility. It is found in the southern Lofty Ranges, Fleurieu Peninsula and on Kangaroo Island.
