Hypocalymma is a genus of evergreen shrubs in the myrtle family Myrtaceae described as a genus in 1840. [1] [2] The entire genus is endemic to southern Western Australia. [3]
The following is a list of formally described Hypocalymma species and subspecies accepted by the Australian Plant Census as at August 2020: [4]
Myrtaceae, the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pōhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group. All species are woody, contain essential oils, and have flower parts in multiples of four or five. The leaves are evergreen, alternate to mostly opposite, simple, and usually entire. The flowers have a base number of five petals, though in several genera, the petals are minute or absent. The stamens are usually very conspicuous, brightly coloured, and numerous.
Darwinia, sometimes commonly known as mountain bells or simply bells, is a genus of about 70 species of evergreen shrubs in the family Myrtaceae, endemic to southeastern and southwestern Australia. The majority are native to southern Western Australia, but a few species occur in South Australia, New South Wales and Victoria. The genus was named in honour of Erasmus Darwin, grandfather of Charles Darwin by Edward Rudge in 1816. Most darwinias grow to a height of between 0.2 and 3 m, and many are prostrate shrubs. Most have small, simple leaves and the flowers are often grouped together, each flower with five red, white or greenish petals and ten stamens. In many species, the flowers are surrounded by large, colourful bracts, giving rise to their common names.
Chamelaucium, also known as waxflower, is a genus of shrubs endemic to south western Western Australia. They belong to the myrtle family Myrtaceae and have flowers similar to those of the tea-trees (Leptospermum). The most well-known species is the Geraldton wax, Chamelaucium uncinatum, which is cultivated widely for its large attractive flowers.
Thryptomene is a genus of flowering plants in the family Myrtaceae and is endemic to Australia. Plants in the genus Thryptomene are shrubs with small leaves arranged in opposite pairs and white or pink flowers. About forty-seven species of Thryptomene, occurring in all Australian states and the Northern Territory, have been formally described.
Calytrix is a genus of about 83 species of flowering plants, commonly known as star flowers, in the family Myrtaceae and is endemic to Australia. Plants in the genus Calytrix are small to large shrubs with small, spreading and more or less round leaves, the flowers arranged singly in leaf axils. The flowers are bisexual with 5 overlapping sepals with a long awn, and many stamens.
Scholtzia is a genus of flowering plants in the family Myrtaceae, which are endemic to the south-west of Western Australia. The genus was first described by Schauer in 1843, who named it in honour of the physician Heinrich Scholtz. The type species is Scholtzia obovata.
Hypocalymma xanthopetalum, commonly known as yellow myrtle, is a species of flowering plant in the myrtle family Myrtaceae, and is endemic to the south-west of Western Australia. It is a low-growing to erect or sprawling shrub with sessile, oblong leaves, and pale to bright yellow flowers with 80 to 135 stamens.
Hypocalymma angustifolium, commonly known as white myrtle, or pink-flowered myrtle, is a species of flowering in the myrtle family Myrtaceae, and is endemic to the south west region of Western Australia. The Noongar peoples know the plant as koodgeed or kudjidi. It is an erect, multi-stemmed shrub with narrowly linear leaves, white or pale pink flowers.
Hypocalymma robustum, commonly known as Swan River myrtle, is a species of flowering plant in the myrtle family Myrtaceae, and is endemic to the south-west of Western Australia. It is an erect, multistemmed shrub or shrublet with linear to narrowly oblong leaves and pink flowers arranged in pairs in leaf axils, with 35 to 60 stamens.
Chamelaucieae is a tribe of flowering plants within the family Myrtaceae, mostly from Australia, with a few species in New Caledonia and south-east Asia.
Hypocalymma cordifolium is a species of flowering plant in the myrtle family Myrtaceae, and is endemic to the south west of Western Australia. It is usually an low-growing shrub, but is sometimes erect, with winged stems, heart-shaped leaves arranged in opposite pairs, white or pale pink flowers mostly arranged in pairs in leaf axils, and fruit containing pearly white or pale brown seeds.
Hypocalymma gardneri is a species of flowering plant in the myrtle family Myrtaceae, and is endemic to the south west of Western Australia. It is a widely spreading subshrub, with linear leaves and yellow flowers arranged in pairs in leaf axils, with 80 to 105 stamens in several rows.
Hypocalymma jessicae, commonly known as Barrens myrtle, is a species of flowering plant in the myrtle family Myrtaceae, and is endemic to the south west of Western Australia. It is an erect, spreading shrub, with narrowly egg-shaped leaves with the narrower end towards the base, and pale to bright pink flowers mostly arranged in pairs in leaf axils, with 35 to 100 stamens in several rows.
Hypocalymma melaleucoides, commonly known as Fitzgerald myrtle, is a member of the family Myrtaceae and is endemic to the Fitzgerald River National Park in the south of Western Australia. It is a spreading shrub with linear leaves that are round in cross-section, and bright pink flowers, with 35 to 55 stamens in several rows.
Hypocalymma minus is a species of flowering plant in the myrtle family Myrtaceae, and is endemic to the south west of Western Australia. It is a low-growing shrub, with heart-shaped leaves arranged in opposite pairs, white or pale pink flowers usually arranged singly in leaf axils with 10 to 20 stamens in one or two rows.
Hypocalymma puniceum, commonly known as large myrtle, is a species of flowering plant in the myrtle family Myrtaceae, and is endemic to the south-west of Western Australia. It is a spreading shrub with linear leaves and bright pink flowers arranged singly in leaf axils, with 35 to 55 stamens in several rows.
Hypocalymma scariosum is a species of flowering in the myrtle family Myrtaceae, and is endemic to the south of Western Australia. It is an erect, apparently short-lived, glabrous shrublet, with grooved linear leaves, and cream-coloured or sometimes yellow flowers with 12 to 20 stamens.
Hypocalymma sylvestre commonly known as Chittering myrtle, is a species of flowering in the myrtle family Myrtaceae, and is endemic to a restricted part of the south-west of Western Australia.
