'''''Cussonia''''' is a genus of plants of the family Araliaceae, which is native to the Afrotropics. It originated in Africa and has its center of distribution in South Africa and the Mascarene Islands<!--apparently not Madagascar-->. Due to their striking habit, they are a conspicuous and easily recognizable group of plants. Their genus name commemorates the botanist Pierre Cusson.<ref name="gav">{{cite web |last1=Gavhi |first1=Peter |last2=Harris |first2=Shireen |last3=Reynolds |first3=Yvonne |title=Cussonia paniculata Eckl. & Zeyh. | date = October 2002 |url=https://www.plantzafrica.com/plantcd/cussoniapan.htm |website=PlantZAfrica.com|publisher=SANBI |accessdate=25 April 2017}}</ref> The Afro-Malagasy and Asian ''Schefflera'', and Afrotropical ''Seemannaralia'' genera are related taxa that share several of its morphological characteristics, among which the leaves borne on the end of branches, inflorescences carried on terminal branches or stems, and reduced leaf complexity in developing inflorescences.<ref name="dev">{{cite journal|last1=de Villiers |first1=Bernard J. |last2=Tilney|first2=Patricia M. |last3=van Wyk |first3=Ben-Erik |title=The taxonomic significance of leaf anatomical characters in Cussonia and related genera (Araliaceae)|journal=Botanical Journal of the Linnean Society |date=2010 |volume=164 |issue=3 |pages=246–263 |url=http://ben-erikvanwyk.com/247%20-%202010,%20De%20Villiers,%20Tilney,%20Van%20Wyk,%20Cussonia%20leaf%20anatomy.pdf |accessdate=25 April 2017 |doi=10.1111/j.1095-8339.2010.01085.x|doi-access=free }}</ref>
==Range and habitat== They occur in grasslands, woodlands and forests, from sea level to over 2,000 metres in altitude. Geographically, they are indigenous to sub-Saharan Africa, Yemen in the Arabian Peninsula and the Comoro Islands.<ref name="dev"/>
==Habit and morphology== They are squat to lanky shrubs and trees with a palm-like habit. Their leaves are typically grouped in umbrella-shaped arrangements at the tips of long erect branches. The leaves are carried on long petioles, and have conspicuous stipules. The leaves are very variable in shape, often palmately compound (''cf.'' subgenus ''Paniculata'' <small>Strey</small>)<ref name="dev"/> with leaflets likewise variable in shape, but also simple or palmate. Their usually dense inflorescences are often spiked, and their small flowers usually have 5 greenish petals.<ref name="hyd">{{cite web |last1=Hyde |first1=M.|display-authors=et al |title=''Cussonia'' |url=http://www.zimbabweflora.co.zw/speciesdata/genus.php?genus_id=1032 |website=Flora of Zimbabwe |publisher=zimbabweflora.co.zw |accessdate=25 April 2017}}</ref> Their stems and underground parts are succulent,<ref name="dev"/> and their bark is often corky.<ref name="tho">{{cite book |last1=Thomas |first1=Val |last2=Grant |first2=Rina |last3=van Gogh |first3=Joan |title=Sappi tree spotting: Kwazulu-Natal and Eastern Cape |date=2004 |publisher=Jacana |location=Johannesburg |isbn=9781770090385 |pages=78–79}}</ref> These plants are best grown from seed.
