botryopterid

Definitions

Any extinct primitive fern of the genus Botryopteris.

Examples

“The botryopterids (Botryopteriaceae) include⟳ three or four genera, all based on stem anatomy, with fruiting organs known also in one genus.”

“To date⟳ it has been assumed that most Middle and Upper Pennsylvanian botryopterids produced sporangial aggregations similar to B. globosa and that all botryopterid species of this age produced Punctatisporites-like spores.”
