The Arecaceae are a botanical family of perennial trees, climbers, shrubs, and acaules commonly known as palm trees (owing to historical usage, the family is alternatively called Palmae).
Blechnum (hard fern) is a genus of between 150–220 species of ferns with a cosmopolitan distribution, in the family Blechnaceae in the eupolypods II clade of the order Polypodiales.
Botany, also called plant science(s), plant biology or phytology, is the science of plant life and a branch of biology.
Cycads are seed plants with a long fossil history that were formerly more abundant and more diverse than they are today.
A fern is a member of a group of vascular plants that reproduce via spores and have neither seeds nor flowers.
Fern sports are plants that show marked change from the normal type or parent stock as a result of mutation.
Frond dimorphism refers to a difference in ferns between the fertile and sterile fronds.
The following is a defined list of terms which are used to describe leaf morphology in the description and taxonomy of plants.
A leaf is an organ of a vascular plant and is the principal lateral appendage of the stem.
Ophioglossales (lit. 'snake-tongue ') are a small group of pteridophyte plants.
In botany, the petiole is the stalk that attaches the leaf blade to the stem.
Pinnation (also called pennation) is the arrangement of feather-like or multi-divided features arising from both sides of a common axis.
In botany and dendrology, a rhizome (from script "mass of roots", from rhizóō "cause to strike root") is a modified subterranean stem of a plant that sends out roots and shoots from its nodes.
A sorus (pl. sori) is a cluster of sporangia (structures producing and containing spores) in ferns and fungi.
A sporangium (pl., sporangia) (modern Latin, from Greek σπόρος (sporos) ‘spore’ + αγγείον (angeion) ‘vessel’) is an enclosure in which spores are formed.
In botany, a stipe is a stalk that supports some other structure.
Vernation (from vernal meaning spring, since that is when leaves spring forth in temperate regions) is the formation of new leaves or fronds.
