Verticordia muelleriana is a species of flowering plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is an openly branched shrub with relatively large, egg-shaped to circular leaves and long spikes of deep maroon coloured flowers in spring and early summer.
Verticordia muelleriana is a shrub which grows to a height of up to 2 m (7 ft) with a single main branch with a few side branches. Its leaves are egg-shaped to almost circular, 3–7 mm (0.1–0.3 in) long and have thin edges.[2]
The flowers are arranged in spikes along the branches, opening in sequence from the lowest flowers, each flower on a stalk about 1 mm (0.04 in) long. The floral cup is top-shaped, 3.5 mm (0.1 in) long, glabrous and slightly rough with green appendages about 1 mm (0.04 in) long. The sepals are a deep maroon colour, spreading, 4–5 mm (0.16–0.20 in) long and have 8 or 9 feathery lobes and two large, hairy, ear-like appendages. The petals are a similar colour, erect, 5 mm (0.2 in) long, 3.5 mm (0.1 in) wide with a fringe a further 2 mm (0.08 in) and also have small, hairy, ear-like appendages. The style is 7 mm (0.3 in) long, curved, and densely hairy near the tip. Flowering time is from September to January.[2]
Taxonomy and naming
Verticordia muelleriana was first formally described by Ernst Pritzel in 1904 from a specimen he collected between Watheroo and Coorow and the description was published in Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pflanzengeographie.[1][3] The specific epithet (muelleriana) honours Ferdinand von Mueller.[2]
The names of two subspecies are accepted by the Australian Plant Census:
- Verticordia muelleriana subsp. minor A.S.George which has sepals 3.5 mm (0.1 in) long and petals 4 mm (0.16 in)s long, including a fringe 0.5 mm (0.02 in) long.[4][5]
- Verticordia muelleriana E.Pritzl. subsp. muelleriana that has sepals and petals 5 mm (0.20 in) long, including a fringe 1.5 mm (0.06 in)s long;[4][6]
When Alex George reviewed the genus Verticordia in 1991, he placed this species in subgenus Eperephes, section Pennuligera along with V. chrysostachys, V. lepidophylla, V. aereiflora, V. dichroma, V. x eurardyensis, V. comosa, V. argentea, V. albida, V. fragrans, V. venusta, V. forrestii, V. serotina, V. oculata, V. etheliana and V. grandis.[4]
Distribution and habitat
This verticordia grows in sand, sometimes with lateritic gravel, usually with other species of Verticordia in woodland and shrubland. It occurs between Coomberdale and Watheroo[2] in the Avon Wheatbelt, Geraldton Sandplains and Jarrah Forest biogeographic regions.[7][8]
