Goodenia heterophylla is a species of plant in the family
Goodeniaceae and is
endemic to eastern Australia. It is an erect to trailing, more or less woody
herb or shrub with linear to egg-shaped stem-leaves and
racemes or
thyrses of yellow flowers.
Description
Goodenia heterophylla is an erect to trailing, more or less woody herb or shrubby plant that grows to a height of up to 40 cm (16 in). The leaves on the stem are linear to egg-shaped, 10–40 mm (0.39–1.57 in) long and 2–10 mm (0.079–0.394 in) wide and
sessile, sometimes with toothed or lobed edges. The leaves at the base of the plant are
ephemeral. The flowers are arranged in leafy racemes or thyrses up to 300 mm (12 in) long on a
peduncle 6–15 mm (0.24–0.59 in) long with linear
bracteoles 2–4 mm (0.079–0.157 in) long. Each flower is on a
pedicel 4–7 mm (0.16–0.28 in) long with linear to lance-shaped
sepals 2–4 mm (0.079–0.157 in) long. The
corolla is up to 12 mm (0.47 in) long, the lower lobes up to 5 mm (0.20 in) long with wings up to 1.5 mm (0.059 in) wide. Flowering mainly occurs from August to May and the fruit is a broadly oval
capsule up to 3 mm (0.12 in) long.[3][4][5][6]
Goodenia heterophylla subsp. eglandulosaCarolin,[9] an ascending to erect herb that differs from the
autonym in lacking
glandular hairs and having serrated, egg-shaped leaves;[10][11][12]
Goodenia heterophylla Sm. subsp. heterophylla[13] (the autonym), an ascending to erect herb with usually egg-shaped leaves 15–30 mm (0.59–1.18 in) long and 3–8 mm (0.12–0.31 in) wide, usually serrated, the foliage with simple and glandular hairs;[14][15]
Goodenia heterophylla subsp. montana Carolin,[16] an erect, more or less woody herb that differs from the autonym in having linear to narrow oblong leaves 15–25 mm (0.59–0.98 in) long and 2–3 mm (0.079–0.118 in) wide with smooth edges that are turned downwards, the foliage covered with woolly or cottony hairs;[17][18]
Goodenia heterophylla subsp. teucriifolia (
F.Muell.) Carolin,[19] formerly known as Goodenia teucriifolia F.Muell., a low-lying to spreading herb with flat, egg-shaped leaves 10–40 mm (0.39–1.57 in) long and 5–15 mm (0.20–0.59 in) wide with serrated edges and that is endemic to Queensland.[20]
Distribution and habitat
This goodenia grows in forest and woodland, often on sandstone. Subspecies eglandulosa occurs in coastal and tableland areas of New South Wales from near
Wauchope to
Jervis Bay in New South Wales.[12][11] Subspecies heterophylla is mostly found between
Gloucester and
Lithgow in New South Wales but sometimes also in north eastern Victoria.[15][14][21] Subspecies montana is found in forest between Lithgow and the
Nerriga area[18][17] and subsp. teucriifolia is restricted to the
Glass House Mountains area in Queensland.[20]
