Eucalyptus argillacea
species of eucalyptus
Eucalyptus argillacea, commonly known as Mount House box, or northern grey box is a tree that is endemic to northern Australia. It has rough, fibrous bark, lance-shaped adult leaves, flower buds usually in groups of seven, creamy white flowers and conical fruit.
Description
Eucalyptus argillacea is a tree that typically grows to a height of 4 to 14 metres (13 to 46 ft) 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, 50–140 mm (2.0–5.5 in) long and 7–35 mm (0.3–1 in) wide on a petiole 5–23 mm (0.20–0.91 in) long. The flower buds are arranged in groups of between three and seven on a peduncle 3–15 mm (0.1–0.6 in) long, the individual buds on a pedicel 2–5 mm (0.08–0.2 in) long. The mature buds are pear-shaped, oval or spindle-shaped, 6–10 mm (0.24–0.39 in) long and 4–6 mm (0.2–0.2 in) wide with a conical to beaked operculum 2–3 mm (0.079–0.12 in) long and 3–4 mm (0.12–0.16 in) wide. Flowering occurs from April to July or from October to December and the flowers are creamy white. The fruit is a conical capsule, 6–10 mm (0.24–0.39 in) long and 4–6 mm (0.16–0.24 in) wide.
This species is similar to other box-type eucalypts found in tropical areas including E. tectifica, E. distans and E. obconica.
Taxonomy and naming
Eucalyptus argillacea was first formally described in 1918 by William Vincent Fitzgerald and the description was published 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.
The public source identifies “Eucalyptus argillacea” as species of eucalyptus. This brief keeps that definition visible, then builds a research path around Eucalyptus, argillacea and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Eucalyptus argillacea”, the useful work is to connect “species of eucalyptus” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q15397376. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1918 and 1905.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
