It has broad egg-shaped to elliptical leaves, white flowers usually borne singly on short side shoots, and fruit that remains on the plant until it dies.

Description

Leptospermum myrtifolium is a shrub that typically grows to a height of {{cvt|1-3|m}}. It has thin, rough bark that is shed in flaky layers on the older stems and young stems that are softly-hairy at first. The leaves are broadly egg-shaped to elliptical, {{cvt|5–10|mm}} long and {{cvt|2–5|mm}} wide, tapering to a thin petiole about {{cvt|1|mm}} long. The flowers are borne singly, sometimes in pairs, on short side shoots, and are white and {{cvt|7–10|mm}} wide. There are broad reddish brown bracts at the base of the flower bud but which fall off well before the flower opens. The floral cup is mostly glabrous, {{cvt|2–3|mm}} long on a thin pedicel about {{cvt|1|mm}} long. The sepals are broadly egg-shaped, about {{cvt|2|mm}} long, the petals {{cvt|3–3.5|mm}} long and the stamens {{cvt|1.5–2|mm}} long. Flowering mainly occurs from January to February and the fruit is a hemispherical capsule {{cvt|4–6|mm}} wide that remains on the plant until it dies.{{cite journal |last1=Thompson |first1=Joy |title=A revision of the genus Leptospermum (Myrtaceae) |journal=Telopea |date=1989 |volume=3 |issue=3 |pages=409–410}}{{cite web |last1=Lyne |first1=Andrew |title=Leptospermum myrtifolium |url=https://vicflora.rbg.vic.gov.au/flora/taxon/e67bc098-7731-4287-866e-ccc306e9bbb3 |publisher=Royal Botanic Gardens, Victoria |accessdate=30 April 2020}}

Taxonomy and naming

Leptospermum myrtifolium was first formally described in 1825 by Augustin Pyramus de Candolle in his book Prodromus Systematis Naturalis Regni Vegetabilis{{cite book |last1=de Candolle |first1=Augustin Pyramus |title=Prodromus Systematis Naturalis (Volume 3) Regni Vegetabilis |date=1828 |publisher=Sumptibus Sociorum Treuttel et Würtz |location=Paris |page=228 |url=https://www.biodiversitylibrary.org/item/7152#page/239/mode/1up |accessdate=1 May 2020}} from an unpublished description by Franz Sieber.{{cite web|title=Leptospermum myrtifolium|url= https://id.biodiversity.org.au/instance/apni/526080 |publisher=APNI|accessdate=1 May 2020}} The specific epithet (myrtifolium) is from Latin words meaning "myrtle-leaved".{{cite book |author=Francis Aubie Sharr|title=Western Australian Plant Names and their Meanings |date=2019 |publisher=Four Gables Press |location=Kardinya, Western Australia |isbn=9780958034180 |page=258}}
