'''''Bursaria longisepala''''' is a species of flowering plant in the family Pittosporaceae and is endemic to New South Wales. It is a spiny, sprawling shrub with narrowly elliptic leaves clustered around spiny side-shoots, flowers with relatively large sepals, five spreading white petals and five stamens, and concave fruit.
==Description== ''Bursaria longisepala'' is a spiny, sprawling shrub that typically grows to a height of less than {{cvt|1|m}}, some stands retaining juvenile characteristics. Young plants have clustered, thin, more or less sessile elliptic leaves {{cvt|8–12|mm}} long and {{cvt|1.0–1.5|mm}} wide with toothed edges. Adult plants have sessile, dark green, narrowly elliptic leaves {{cvt|6–9|mm}} long and {{cvt|1–3|mm}} wide clustered around spiny side-shoots. The flowers are arranged singly, in pairs or in small groups at the ends of branchlets, each flower on a pedicel {{cvt|2–5|mm}} long. The sepals are larger in this species than in others of the genus, green or cream-coloured, {{cvt|3.5–4.0|mm}} long, free from each other and spreading from the base. The five petals are white and spread from the base, {{cvt|6–8|mm}} long. Flowering mainly occurs in summer and the fruit is a concave capsule {{cvt|5–6|mm}} long and {{cvt|5–8|mm}} wide.<ref name="FoA">{{cite web |title=''Bursaria longisepala'' |url=https://profiles.ala.org.au/opus/foa/profile/Bursaria%20longisepala |publisher=Australian Biological Resources Study, Department of Agriculture, Water and the Environment: Canberra |access-date=5 November 2021}}</ref><ref name="RBGS">{{cite web |last1=Conn |first1=Barry J. |title=''Bursaria longisepala'' |url=https://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Bursaria~longisepala |publisher=Royal Botanic Garden Sydney |access-date=5 November 2021}}</ref>
==Taxonomy== ''Bursaria longisepala'' was first formally described in 1926 by Karel Domin in the journal ''Bibliotheca Botanica'' from specimens he collected in the Blue Mountains in 1910.<ref name=APNI>{{cite web|title=''Bursaria longisepala''|url= https://id.biodiversity.org.au/instance/apni/480858|publisher=APNI|access-date=5 November 2020}}</ref>
==Distribution and habitat== This bursaria mostly grows on south-facing cliffs and in disturbed areas in forest and woodland and is mainly found in the Blue Mountains and sometimes on the central coast of New South Wales.<ref name="FoA" /><ref name="RBGS" />
