Definitions

1. Pertaining to a botanical classification of plants that exhibit palm-like characteristics but belong to a more ancient group called gymnosperms that reproduce through cones
2. Referring to a type of plant related to cycads, recognized for their large, woody structures, distinctive foliage resembling ferns, and slow growing nature
3. Relating to a group of plants known for their resemblance to palms and ferns, characterized by woody stems, cone production, and ancient origins within gymnosperms

Etymology: "Cycadaceous" is a plain formation: it takes the family name "Cycadaceae", the botanical name for the cycad family, and adds the English adjective-forming suffix "-ous", meaning "having the qualities of" or "belonging to". The family name is itself a Latinized scientific coinage built on the genus "Cycas", which comes from the Greek "kykas", a name for a palm-like plant. Cycads are often mistaken for palms because of their crowns of large, feathery leaves, but they are gymnosperms, a group that bears its seeds openly on cones rather than enclosed in fruit. Because the word is a technical taxonomic adjective, its history is essentially the history of the scientific names behind it. The "-aceae" ending marks a family in plant classification, and English botanists attached "-ous" to such family names to make adjectives for describing members of that group. The result is a word used mostly in botany texts, where it lets a writer say that a plant or fossil belongs to the cycad family without naming the family outright.
