}}Utrechtiaceae is an extinct family of trees related to modern conifers.[1] This family dates back to the late Carboniferous and early Permian.[2]DescriptionThey were forest trees with almost horizontal standing leafy lateral shoots and with vertical tribes.They were generally small trees.[2] At least with Utrechtia piniformis the side shoots are in whorls.[3] Like other Voltzialean plants they had compact ovulate cones bearing bilateral bract-scale complexes. The leaves are scale-like, arranged spirally and only a few millimeters long. GeneraUtrechtiaceae include the following selected genera:[1][2]- Ernestiodendron Florin, 1934
- Lebachiella S.V. Meyen, 1997
- Ortiseia R. Florin, 1964
- Moyliostrobus C.N. Miller & J.T. Brown, 1973 : known from the Lower Permian of Texas (Moyliostrobus texanum).
- Otovicia
- Utrechtia G.W. Rothwell & G. Mapes, 2003
