description

Summary In the monogeneric family Ctenolophonaceae extrastaminal discs are developed, whose parenchyma and marginally stomata bearing epidermis appear to be adenoid. The discs are extensively vascularized by phloematic branches derived from bundles of the adnate stamens. The flowers are unshowy, simply constructed and without special nectar protecting structures. Pollinators are still unknwon, but nectar-exploiting bees and flies probably predominate. The Ctenolophonaceae are closely connected with Humiriaceae. Presumed affinities with Malpighiaceae are questioned.
