|genus = Goniothalamus |species = velutinus |authority = Airy Shaw }}Goniothalamus velutinus is a species of plant in the family Annonaceae. It is native to Borneo.[1] Herbert Airy Shaw,[2] the English botanist who first formally described the species, named it after the dense velvety (velutinus in Latin) hair on its branchlets and the midrib of the leaves.[3] Bioactive compounds extracted from its bark have been reported to have antioxidant activities using in vitro tests, anti-biofilm activity in tests with Streptococcus mutans and Proteus mirabilis, and cytostatic activity in tests with cultured human cancer cells.[4][5] DescriptionIt is a tree reaching 6 meters in height. Its leaves are 40-42 by 8.5-10 centimeters and have rusty-brown, velvety hair on their midribs. Its small branches are covered in dense velvety hair. It has green flowers. Its 3 sepals are triangular, 7 by 4 millimeters. Its 6 petals are arranged in two rows of 3. The outer petals are 1.8 centimeters by 8 millimeters. The inner petals are 1.2 centimeters by 6 millimeters. It has numerous stamens. Reproductive biologyThe pollen of G. velutinus is shed as permanent tetrads.[6] References1. ^{{cite web |url= http://www.plantsoftheworldonline.org/taxon/urn:lsid:ipni.org:names:73273-1 |title= Goniothalamus velutinus Airy Shaw|author= |date=n.d. |website=Plants of the World Online |publisher=The Trustees of the Royal Botanic Gardens, Kew |access-date=February 5, 2019}} {{Taxonbar|from=Q15359588}}2. ^{{cite journal |last1=Radcliffe-Smith |first1=A |last2=Harley |first2=R.M. |date=1987 |title= H.
