Ticodendron incognitum is the only species of Ticodendron, and the only member of the family Ticodendraceae. It is most closely related to the family Betulaceae.

It was discovered only in 1989 in Costa Rica, having been overlooked previously due to its habitat in poorly researched cloud forests and its very 'ordinary' appearance; further research showed its range extends from southern Mexico (Veracruz, Oaxaca, Chiapas), south through Central America to Panama.[http://apps.kew.org/wcsp/namedetail.do?name_id=205750 Kew Checklist of Selected Plant Families]Nelson Sutherland, C.H.

It is a tree, 20–30 m tall, superficially resembling an alder in appearance, with alternate, simple leaves 5–12 cm long with a serrated margin. It is generally dioecious, with separate male and female plants.{{cite book|doi=10.1007/978-3-662-02899-5_72|chapter=Ticodendraceae|title=Flowering Plants · Dicotyledons|year=1993|last1=Kubitzki|first1=K.|pages=594–596|isbn=978-3-642-08141-5}}

Fossil record

Ferrignocarpus bivalvis fossil fruits, from the Middle Eocene of Oregon and the Early Eocene London Clay flora of southern England, correspond closely in morphology and anatomy to fruits of extant Ticodendron.{{cite journal |title=Fruits of Ticodendraceae (Fagales) from the Eocene of Europe and North America |first=Steven R. |last=Manchester |journal=International Journal of Plant Sciences |volume=172 |issue=9 |pages=1179–87 |date=November 2011 |doi=10.1086/662135 |s2cid=84609421 }}
