Leucopogon fletcheri is a species of flowering plant in the heath family Ericaceae and is endemic to south-eastern continental Australia. It is a densely-branched shrub with sharply-pointed oblong leaves, and pendent, tube-shaped white flowers in pairs in upper leaf axils.

Description

Leucopogon fletcheri is a densely-branched shrub that typically grows to a height of up to 1.8 m (5 ft 11 in) and has rough-textured branchlets. Its leaves are oblong to linear and sharply pointed, 3.7–8 mm (0.15–0.31 in) long and 1.4–3.1 mm (0.055–0.122 in) wide on a petiole up to 0.3 mm (0.012 in) long. The flowers are white and pendent, arranged singly, in pairs or threes in upper leaf axils on a peduncle up to 1.5 mm (0.059 in) long, with bracteoles 1.2–1.6 mm (0.047–0.063 in) long at the base. The sepals are 2.6–4.7 mm (0.10–0.19 in) long, the petal tube 2.6–4.8 mm (0.10–0.19 in) long and softly hairy above the middle, the lobes 2.4–3.8 mm (0.094–0.150 in) long. Flowering occurs from August to October and the fruit is a glabrous, egg-shaped to elliptic drupe 3.0–5.3 mm (0.12–0.21 in) long.[2]

Taxonomy

Leucopogon fletcheri was first formall described in 1897 by Joseph Maiden and Ernst Betche in the Proceedings of the Linnean Society of New South Wales from specimens collected near Springwood by Joseph James Fletcher in September 1887.[3][4]

In 1993, Jocelyn Marie Powell and G.Robertson described subspecies brevisepalus in the journal Telopea and the name, and that of the autonym, are accepted by the Australian Plant Census:[5]

  • Leucopogon fletcheri Maiden & Betche subsp. brevisepalus[6] typically grows to a height of 0.3–1.0 m (1 ft 0 in – 3 ft 3 in), has leaves 3.7–7.8 mm (0.15–0.31 in) long and 1.7–3.1 mm (0.067–0.122 in) wide, a petal tube 2.6–3.9 mm (0.10–0.15 in) long, the lobes 2.4–3.1 mm (0.094–0.122 in) long and fruit 3.0–3.4 mm (0.12–0.13 in) long.[5]
  • Leucopogon fletcheri subsp. fletcheri Maiden & Betche[7] typically grows to a height of 1.5–1.8 m (4 ft 11 in – 5 ft 11 in), has leaves 4.5–8.0 mm (0.18–0.31 in) long and 1.4–1.9 mm (0.055–0.075 in) wide, a petal tube 3.5–4.8 mm (0.14–0.19 in) long, the lobes 2.8–3.8 mm (0.11–0.15 in) long and fruit 4.7–5.0 mm (0.19–0.20 in) long.[5]

Distribution and habitat

This leucopogon grows in woodland in New South Wales, the Australian Capital Territory, and in montane and subalpine areas of eastern Victoria where it is known as Styphelia fletcheri subsp. brevisepala.[2][5][8] Subspecies fletcheri grows in woodland and shrubland, but is restricted to the area between St Albans and Annangrove in north-western Sydney.[2][5][9]

Conservation status

Leucopogon fletcheri is listed as "endangered" under the New South Wales Government Biodiversity Conservation Act 2016. The main threats to the subspecies include habitat loss and fragmentation, inappropriate fire regimes and weed invasion.[9]

Taxonomy

Leucopogon esquamatus was first formally described in 1810 by Robert Brown in his Prodromus Florae Novae Hollandiae.[1][2] The specific epithet (esquamatus) means "without scales", possibly to distinguish it from other similar plants with scale-like leaves.[3]

Distribution and habitat

Swamp beard-heath usually grows in swampy heath, sometimes in forest or at the base of sandstone cliffs and is found in New South Wales south from Brooms Head near Angourie to poorly-drained near-coastal heath as far west as Marlo in north-eastern Victoria. It also grows on sandy headlands on Flinders and Cape Barren Islands in Tasmania.[4][5][6]
