Classification of gymnosperms by gifford and foster?
In early classification schemes, the gymnosperms (Gymnospermae) were regarded as a "natural" group. There is conflicting evidence on the question of whether the living gymnosperms form aclade.[1][2]The fossil record of gymnosperms includes many distinctive taxa that do not belong to the four modern groups, including seed-bearing trees that have a somewhat fern-like vegetative morphology (the so-called seed ferns or pteridosperms.)[3]When fossil gymnosperms such asBennettitales, Caytonia and the glossopterids are considered, it is clear that angiosperms are nested within a larger gymnosperm clade, although which group of gymnosperms are their closest relatives remains unclear. For the most recent classification on extant gymnosperms see Christenhusz et al. (2011)[4]Classification:'SUBCLASS CYCADIDAEORDER CYCADALESFamily Cycadaceae: CycasFamily Zamiaceae: Dioon, Bowenia, Macrozamia, Lepidozamia, Encephalartos, Stangeria,Ceratozamia, Microcycas, Zamia.SUBCLASS GINKGOIDAEORDER GINKGOALESFamily Ginkgoaceae: GinkgoSUBCLASS GNETIDAEORDER WELWITSCHIALESFamily Welwitschiaceae: WelwitschiaORDER GNETALESFamily 'Gnetaceae: GnetumORDER EPHEDRALESFamily Ephedraceae: EphedraSUBCLASS PINIDAEORDER PINALESFamily Pinaceae: Cedrus, Pinus, Cathaya, Picea, Pseudotsuga, Larix, Pseudolarix,Tsuga, Nothotsuga, Keteleeria, AbiesORDER ARAUCARIALESFamily Araucariaceae: Araucaria, Wollemia, AgathisFamily Podocarpaceae: Phyllocladus, Lepidothamnus, Prumnopitys, Sundacarpus,Halocarpus, Parasitaxus, Lagarostrobos, Manoao, Saxegothaea, Microcachrys,Pherosphaera, Acmopyle, Dacrycarpus, Dacrydium, Falcatifolium, Retrophyllum, Nageia,Afrocarpus, PodocarpusORDER CUPRESSALESFamily Sciadopityaceae: SciadopitysFamily Cupressaceae: Cunninghamia, Taiwania, Athrotaxis, Metasequoia, Sequoia, Sequoiadendron, Cryptomeria, Glyptostrobus,Taxodium, Papuacedrus, Austrocedrus, Libocedrus, Pilgerodendron, Widdringtonia, Diselma, Fitzroya, Callitris, Actinostrobus,Neocallitropsis, Thujopsis, Thuja, Fokienia, Chamaecyparis, Cupressus, Juniperus, Calocedrus, Tetraclinis, Platycladus, MicrobiotaFamily Taxaceae: Austrotaxus, Pseudotaxus, Taxus, Cephalotaxus, Amentotaxus, Torreya
