The genus name is spelled Brachycome by some authors. Henri Cassini published the name Brachyscome in 1816, forming it from the classical Greek brachys ("short") and kome ("hair"), a reference to the very short pappus bristles. Because the combining form of brachys in Greek compound words is brachy-, Cassini later corrected the spelling to Brachycome. Australian taxonomists still debate whether Cassini's corrected spelling is admissible under the International Code of Botanical Nomenclature. A proposal to conserve Brachycome was rejected in 1993 by the ICBN's Committee for Spermatophyta.
These are annual and perennial herbs and small shrubs. Species have a basal rosette of leaves and/or leaves alternately arranged on the stem. The blades are entire or divided. The flower heads are solitary or borne in small corymbs. The head has a row of ray florets in shades of white, blue, pink, or mauve, and yellow disc florets.
The genus is distinguished from other genera in tribe Astereae mainly by the structure of the fruit. These achenes or cypselas are roughly club-shaped but usually incurved and flattened. They often have a membranous rim or wing around the edge that is sometimes wavy or fringed. The pappus is less than one millimeter long in most species.
Brachyscome species are found in a wide range of habitats. They occupy rainy coastal and mountainous regions as well as dry central Australia.
One of the annual plains species, Brachyscome dichromosomatica, is remarkable for its low chromosome count. In this species n=2, though some plants have 1, 2 or 3 additional large B chromosomes. The genus has an unusually large range of chromosome counts, from n=2 to n=18.
