Home›Conifers and Other Gymnosperms›Taxonomy›CycadopsidaTaxaCycadopsidaClassReference and ClassificationVerifiedCycadopsida is the class of cycads, seed plants making up the division Cycadophyta, with a stout woody trunk topped by a crown of large, stiff, evergreen, feather shaped leaves. Cycads are dioecious, meaning each plant is either male or female, and range from a few centimeters to several meters in trunk height, growing slowly and living long lives. Though they superficially resemble palms or ferns, they are not closely related to either, and rely on specialized pollinators, usually a particular beetle, though sometimes a thrips or moth.FactsCycadopsidaConnectionsIn the Other AtlasesSourcesComments (0)Reader Challenges (0)FactsTaxonomic RankWell-attestedClass 2Member Count BandWell-attested100 to 1000 Species 3Era First AppearedWell-attestedDevonian 4ClassificationLiving or ExtinctWell-attestedYes 1CycadopsidaFilter Results4 entriesCommon GroupAllCycads (Cycadales) (4)Everyday GroupAllCycads (Cycadales) (4)HabitatAllTropical Dry Forest (1)Where It LivesAllBahamas (1)Bangladesh (1)Brazil (1)Burkina Faso (1)Colombia (1)Cuba (1)Cyprus (1)Democratic Republic of the Congo (1)Gabon (1)Georgia (1)India (1)Iran (1)Japan (1)Libya (1)Marshall Islands (1)Mexico (1)North America (1)Norway (1)Seychelles (1)South Africa (1)South Asia (1)Taiwan (1)United States (1)Conservation StatusAllEndangered (1)Least Concern (1)Near Threatened (1)DietAllPhotosynthetic Autotroph (4)System (Realm)AllTerrestrial (4)Living or ExtinctAllYes (4)Relationship to PeopleAllEaten or Drunk by People (3)Used in Traditional Medicine (2)CITES AppendixAllAppendix II (4)NatureServe RankAllG3 Vulnerable (1)GNR Unranked (1)EcosystemAllEverglades (1)Show ResultsBrowseCompareSelect all 4Chestnut DioonCycadopsidaCoontieCycadopsidaQueen SagoCycadopsidaSago PalmCycadopsidaConnectionsParent Taxon OfChestnut Dioon, Species Well-attested Source GBIF Backbone Taxonomy: Dioon eduleCoontie, Species Well-attested Source Wikidata: Coontietier 2Queen Sago, Species Well-attested Source Wikidata: Queen SagoSago Palm, Species Well-attested Source Wikidata: Sago PalmIn the Other AtlasesFound InAustraliaAlso in Geography Atlas: where this subject is found.Sources1.
