Leucopogon microphyllus

Leucopogon microphyllus is a bushy or spreading shrub that typically grows to a height of up to {{cvt|1|m}}, its branchlets with fine, bristly hairs. The leaves are egg-shaped leaves, sometimes with the narrower end towards the base, {{cvt|2.2–7.3|mm}} long and {{cvt|1.4–2.5|mm}} wide on a petiole up to {{cvt|0.5|mm}} long. The leaves are more or less glabrous, the upper surface convex and the lower surface with more or less parallel veins. The flowers are arranged in erect spikes of mostly four to nine {{cvt|5–11|mm}} long with bracteoles {{cvt|1.3–1.8|mm}} long at the base. The sepals are {{cvt|2.3–2.7|mm}} long, the petals white and joined at the base to form a tube {{cvt|1.1–1.8|mm}} long with lobes {{cvt|1.5–2.6|mm}} long and softly-hairy inside. Flowering occurs in most months but mainly from August to October, and the fruit is an oblong drupe {{cvt|1.2–1.5|mm}} long.{{cite web |last1=Powell |first1=Jocelyn M. |title=Leucopogon microphyllus |url=https://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Leucopogon~microphyllus |publisher=Royal Botanic Garden Sydney |access-date=30 May 2023}}{{cite journal |last1=Benson |first1=Doug |last2=McDougall |first2=Lyn |title=Ecology of Sydney Plants 3: families Cabombaceae to Eupomatiaceae |journal=Cunninghamia |date=1995 |volume=4 |issue=2 |pages=373–374 |url=https://www.rbgsyd.nsw.gov.au/getmedia/050a0f06-8c1a-4708-8858-b6d2e40fe5c3/Volume-4(2)-1995-Cun4Ben217-431.pdf.aspx |access-date=30 May 2023}}

This species was first formally described in 1797 by Antonio José Cavanilles who gave it the name Perojoa microphylla in his Icones et Descriptiones Plantarum.{{cite web|title=Perojoa microphylla|url= https://id.biodiversity.org.au/instance/apni/515680|publisher=APNI|accessdate=30 May 2023}}{{cite book |last1=Cavanilles |first1=Antonio J. |title=Icones et descriptiones plantarum |volume=4 |date=1797 |page=29 |url=https://bibdigital.rjb.csic.es/viewer/9682/?offset=#page=33&viewer=picture&o=bookmark&n=0&q= |access-date=30 May 2023}} In 1810, Robert Brown transferred the species to Leucopogon as L. microphyllus in his Prodromus Florae Novae Hollandiae et Insulae Van Diemen.{{cite web|title=Leucopogon microphyllusa|url= https://id.biodiversity.org.au/instance/apni/543895|publisher=APNI|accessdate=30 May 2023}}{{cite book |last1=Brown |first1=Robert |title=Prodromus florae Novae Hollandiae et Insulae Van-Diemen, exhibens characteres plantarum |date=1810 |location=London |page=543 |url=https://www.biodiversitylibrary.org/item/21871#page/412/mode/1up |access-date=30 May 2023}} The specific epithet (microphyllus) means "small-leaved".{{cite book |last1=Sharr |first1=Francis Aubi |last2=George |first2=Alex |title=Western Australian Plant Names and Their Meanings |date=2019 |publisher=Four Gables Press |location=Kardinya, WA |isbn=9780958034180 |page=252 |edition=3rd}}

In 1868, George Bentham reduced Leucopogon pilibundus A.Cunn. ex DC. to Leucopogon microphyllus var. pilibundus in Flora Australiensis, and the new name, and that of the autonym are accepted by the Australian Plant Census:

The autonym (var. microphyllus) grows in heath and forest on ridges and hillsides, and is widespread on the coasts and tablelands of New South Wales and the Australian Capital Territory, extending into south-eastern Queensland. It is found at sea level to altitudes of up to {{cvt|1200|m}}. The variety pilibundus grows in open forest and woodland on ridges and on rocky creek banks on near-coastal areas and tablelands of New South Wales, the Australian Capital Territory and north-eastern Victoria, with a disjunct population near Lerderderg Gorge. It grows at altitudes of {{cvt|800–1200|m}}.
