Daviesia ulicifolia

Daviesia ulicifolia is a rigid, openly-branched shrub that typically grows to a height of up to {{cvt|2.5|m}} and has spiny branchlets. Its phyllodes are narrow elliptic, narrow egg-shaped, rarely egg-shaped, {{cvt|5–35|mm}} long and {{cvt|0.5–6|mm}} wide and sharply pointed with a prominent midrib on the upper surface. The flowers are arranged singly or in pairs, sometimes in groups of up to seven, in leaf axils on a peduncle up to {{cvt|3|mm}} long, the rachis up to {{cvt|1.1|mm}} long, each flower on a pedicel {{cvt|0.5–5|mm}} long. The sepals are {{cvt|2–4|mm}} long, the five lobes about {{cvt|0.5–1|mm}} long. Flower colour varies with subspecies, the standard petal broadly egg-shaped with a notched tip, {{cvt|3–6|mm}} long, {{cvt|3–10|mm}} wide, and usually yellow or orange-yellow with a red ring surrounding a yellow centre. The wings are {{cvt|4–6|mm}} long, yellow and dark red, the keel {{cvt|4–5|mm}} long and maroon to red. Flowering occurs from August to October, depending on elevation and latitude, and the fruit is a flattened triangular pod {{cvt|5–8|mm}} long.{{cite journal |last1=Crisp |first1=Michael D. |last2=Cayzer |first2=Lindy |last3=Chandler |first3=Gregory T. |last4=Cook |first4=Lyn G. |title=A monograph of Daviesia (Mirbelieae, Faboideae, Fabaceae) |journal=Phytotaxa |date=2017 |volume=300 |issue=1 |pages=37–44 |doi=10.11646/phytotaxa.300.1.1|doi-access=free }}{{cite web |title=Daviesia ulicifolia |url=http://anpsa.org.au/plant_profiles/daviesia-ulicifolia/ |publisher=Australian Native Plants Society (Australia) |access-date=21 May 2022}}{{Cite web|url=https://www.anbg.gov.au/cpbr/cd-keys/peakey/key/The%20Pea%20Key/Media/Html/davi_ulic_text.html|title=Daviesia ulicifolia|website=www.anbg.gov.au|access-date=2019-12-08}}{{cite web |last1=Crisp |first1=Michael D. |title=Daviesia ulicifolia |url=https://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Daviesia~ulicifolia |publisher=Royal Botanic Garden Sydney |access-date=21 May 2022}}{{cite web |title=Daviesia ulicifolia |url=http://www.flora.sa.gov.au/cgi-bin/speciesfacts_display.cgi?form=speciesfacts&name=Daviesia_ulicifolia |publisher=State Herbarium of South Australia |access-date=21 May 2022}}

Daviesia ulicifolia was first formally described by English botanist Henry Cranke Andrews in 1803 in The Botanist's Repository for New, and Rare Plants.{{cite web|title=Daviesia ulicifolia|url= https://id.biodiversity.org.au/instance/apni/501328|publisher=APNI|access-date=21 May 2022}}{{cite book |last1=Andrews |first1=Henry C. |title=The botanist's repository, for new and rare plants |date=1803 |location=London |page=305 |url=https://www.biodiversitylibrary.org/item/109765#page/33/mode/1up |access-date=21 May 2022}} The specific epithet (ulicifolia) means "gorse-leaved", referring to the distribution of this leucopogon, compared to others in the genus.{{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=331 |edition=3rd}}

In 1997, Gregory T. Chandler and Michael Crisp described six subspecies of D. ulicifolia in Australian Systematic Botany, and the names are accepted by the Australian Plant Census:

Gorse bitter-pea is widely distributed in Australia, where it grows in open forest in all six states, but not the Northern Territory.

• Subspecies aridicola grows in arid areas of the Great Victoria Desert and Murchison bioregions of Western Australia, in a broad area of South Australia,{{cite web |title=Census of South Australian Plants |url=http://www.flora.sa.gov.au/cgi-bin/census_display.cgi?datasource=general-public&family=&genus=Daviesia&species=ulicifolia&style=book&format=HTML&submit=Search&synonym=1 |publisher=State Herbarium of South Australia |access-date=21 May 2022}} and in the far south-west of New South Wales.
• Subspecies incarnata grows in hilly or mountain areas in the Mount Lofty Ranges of South Australia and in a few isolated places further south.
• Subspecies pilligensis grows in heathy woodland and open forest from south-eastern Queensland to the western slopes of New South Wales, especially in the Pilliga Scrub.
• Subspecies ruscifolia grows in forest from central New South Wales and the Australian Capital Territory to the Grampians National Park in Victoria, and in Tasmania.
• Subspecies stenophylla is mostly found in coastal areas, often in disturbed habitats from the wet tropics of far north Queensland to the Central Coast of New South Wales.
• Subspecies ulicifolia mostly grows in forest and is widespread from south-eastern Queensland, through most of Victoria to south-eastern South Australia and Tasmania.
