Commersonia is a genus of twenty-five species of flowering plants in the family Malvaceae. Plants in this genus are shrubs or trees, occurring from Indochina to Australia and have stems, leaves and flowers covered with star-like hairs. The leaves are simple, often with irregularly-toothed edges, the flowers bisexual with five sepals, five petals and five stamens and the fruit a capsule with five valves. The genus underwent a revision in 2011 and some species were separated from Commersonia, others were added from Rulingia. [2] [3] [4] [5]

Taxonomy

The genus Coommersonia was first formally described in 1775 by Johann Reinhold Forster and his son Georg Forster in the book Characteres generum plantarum and the first species they described was Commersonia echinata, now known as Commersonia bartramia . [6] [7]

A revision of the genus in 2011 added 3 newly described species, as well as 14 species previously included in Rulingia , and transferred a number of species to the newly created genus Androcalva . [8]

The genus is named after Philibert Commerson (1727–73), a French naturalist who sailed with the Bougainville expedition in 1766 and died on Mauritius. [2]

<i>Leptospermum</i> Genus of shrubs

Leptospermum is a genus of shrubs and small trees in the myrtle family Myrtaceae commonly known as tea trees, although this name is sometimes also used for some species of Melaleuca. Most species are endemic to Australia, with the greatest diversity in the south of the continent, but some are native to other parts of the world, including New Zealand and Southeast Asia. Leptospermums all have five conspicuous petals and five groups of stamens which alternate with the petals. There is a single style in the centre of the flower and the fruit is a woody capsule.

<i>Darwinia</i> (plant) Genus of flowering plants

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.

Sterculiaceae was a family of flowering plant based on the genus Sterculia. Genera formerly included in Sterculiaceae are now placed in the family Malvaceae, in the subfamilies: Byttnerioideae, Dombeyoideae, Helicteroideae and Sterculioideae.
