}}Schizolaena hystrix is a tree in the family Sarcolaenaceae. It is endemic to Madagascar. The specific epithet {{lang|la|hystrix}} is from the Latin meaning "spiny", referring to the porcupine-like appearance of the involucre.[3]DescriptionSchizolaena hystrix grows as a large tree up to {{convert|35|m|-1}} tall. Its leaves are coriaceous.[3] The spiny involucre is fleshy and is thought to attract lemurs, bats and birds who in turn disperse the tree's seeds.Distribution and habitatSchizolaena hystrix is known only from the northeastern regions of Sava, Alaotra-Mangoro, Analanjirofo and Atsinanana.[2] Its habitat is humid evergreen forests from sea-level to {{convert|1500|m|-3|abbr=on}} altitude.ThreatsSchizolaena hystrix is threatened by deforestation and by threats to the lemur. Deforestation due to shifting agriculture is occurring outside protected areas. However, 9 of 14 subpopulations of the tree are within protected areas. Threats to lemurs would in turn affect the tree's reproduction due to the their role in seed dispersal.References1. ^1 2 {{Tropicos | 17 | 28800065 | Schizolaena hystrix | | | accessdate = 29 Oct 2016 }}
