Prehistoric angiosperm genera

dubious genus of prehistoric plant named based on fragments of petrified wood

left|thumb|Fossil cast of A. liaoningensis Archaefructus is an extinct genus of herbaceous aquatic seed plants with three known species. Fossil material assigned to this genus originates from the Yixian Formation in northeastern China, originally dated as late Jurassic but now understood to be approximately 125 million years old, or early Cretaceous in age. Even with its revised age, Archaefructus has been proposed to be one of the earliest known genera of flowering plants. thumb Because of its age, lack of sepals and petals, and the fact that its reproductive organs (carpels and stamens), are

Palaeoraphe is an extinct genus of palms, represented by one species, Palaeoraphe dominicana from early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola, in the modern-day Dominican Republic. ==Discovery and naming== The genus is known from a single, diameter, full flower. The holotype is currently deposited in the collections of the Oregon State University in Corvallis, Oregon, as number "Sd–9–158", where it was studied and described by Dr George Poinar. Dr Poinar published his 2002 type description for Palaeoraphe in the Botanical Journal of the Linnean Society

Palmoxylon, also called petrified palmwood, is an extinct genus of palm named from petrified wood found around the world.

Montsechia is an extinct genus of aquatic plants containing the species Montsechia vidalii, described from Spain. M. vidalii lived about 130 million years ago, during the Barremian age, and appears to be the earliest known flowering plant macrofossil. It has affinities with the modern genus Ceratophyllum. It has been placed in the ceratophyllalean family Montsechiaceae.

Saxonipollis saxonicus is an extinct plant species. It was possibly carnivorous. It is known only from fossilised pollen found in Eocene deposits of East Germany.

Meliorchis caribea is an extinct, early to middle Miocene orchid known only from a packet of pollen attached to the wing of a stingless bee, Proplebeia dominicana, trapped in Dominican amber. It was the first fossil orchid ever described, and allowed for a revised estimate of the time of origin of the Orchidaceae to the Mesozoic. Morphology of the pollinium suggests that M. caribea is closely related to the modern genus Ligeophila.

Fischeripollis is a genus of extinct plants in the family Droseraceae. Several species have been formally described and another has been temporarily designated Fischeripollis sp. A.
