Through Perennial, Flowering plant and Species
Perhaps the best-known (and most popular in cultivation) genera from the family are the unusual Anigozanthos and Macropidia, both commonly called "kangaroo-paw" or "kangaroo's paw" due to their fuzzy flowers. These genera are hugely popular in both private gardens and public landscaping projects in Mediterranean climate regions, such as in Chile, northwestern Mexico (Baja California), Southern California (and the Bay Area) and Western Australia, among other locations; the kangaroo-paws are valued for their hardiness, adaptability and low irrigation requirements, once established.
Taxonomy
The Haemodoraceae were first described by Robert Brown in 1810, and bear his name as the botanical authority. An alternative name has been Haemodoreae
The fourth Angiosperm Phylogeny Group classification of 2016 (unchanged from the earlier APG systems of 2009, 2003 and 1998), also recognizes this family and places it in the order Commelinales, in the clade commelinids, in the monocots. The family of the Haemodoraceae then includes about sixteen sub-tropical or tropical genera found in the southern hemisphere, two in North America and three known cultivated genera in Europe.

Description
Haemodoraceae is characterized by distichous leathery leaves, which are alternate, succulent, rather large and often ensiform, with entire margins and parallel veins. The leaves are enclosed by a sheath with free margins and alternate, distichous (= in two vertical ranks).
The plants are hermaphroditic. Pollinators are primarily insects, but also birds or sometimes a small mammal. The wooly-haired flowers grow at the end of a leaflet stalk, in cymes (with lateral branches), panicles or racemes.
The family is represented in Southwest Australia by extreme diversity, including around six genera that only occur in that region. The endemic species include the kangaroo paws, Anigozanthos and Macropidia, and the most speciose genus of the family, Conostylis.
