Description

Eucalyptus argillacea is a tree that typically grows to a height of Шаблон:Convert with rough, grey, fibrous bark on its trunk and branches. The adult leaves are elliptic to lance-shaped or egg-shaped, light green to greyish green, Шаблон:Convert long and Шаблон:Convert wide on a petiole Шаблон:Convert long. The flower buds are arranged in groups of between three and seven on a peduncle Шаблон:Convert long, the individual buds on a pedicel Шаблон:Convert long. The mature buds are pear-shaped, oval or spindle-shaped, Шаблон:Convert long and Шаблон:Convert wide with a conical to beaked operculum Шаблон:Convert long and Шаблон:Convert wide. Flowering occurs from April to July or from October to December and the flowers are creamy white. The fruit is a conical capsule, Шаблон:Convert long and Шаблон:Convert wide.[1][3][4]

This species is similar to other box-type eucalypts found in tropical areas including E. tectifica, E. distans and E. obconica.[5]

Taxonomy and naming

Eucalyptus argillacea was first formally described in 1918 by William Vincent Fitzgerald and the description was publish in Joseph Maiden's book A Critical Revision of the Genus Eucalyptus from specimens collected by Fitzgerald in 1905 from around the base of Mount House.[6][7] The specific epithet (argillacea) is a Latin word meaning "clayey",[8] referring to the soil at the type location.[3]

Distribution and habitat

Mount House box is found along watercourses and on plains where it grows in alluvium and heavy clay soils. Populations are found only in the Kimberley region of Western Australia.[1][9] George M. Chippendale (1988) recognized its occurrence also in Northern Territory and northern Queensland, synonymizing E. leucophylla Шаблон:Small[10] (now considered to be a separate taxon whose type locality is Queensland)[11] and citing specimens G.M. Chippendale 2171 (now its precise determination withdrawn),[12] R.E. Winkworth 1051, B. Hyland 6283 and L. Pedley 2056 (all of the last three currently re-determined as E. chlorophylla Шаблон:Small).[13][14][15]
