Plant Classification
By: Chloe King
Bryophyta
Common Name: Mosses
Scientific Name: Bryophyta
Group: Seedless nonvascular
Characteristics: Small, low to the ground, no true leaves, and have rhizoids
Habitat: Moist habitats, can live in harsh conditions
Reproduce: They rely on free-standing water to allow their sperm to swim to and fertilize
eggs.
Examples: Goniomitrium acuminatum, Sphagnum wilfii , Papillaria haitensis
Interesting Info: Among the first plants to colonize in early stages of primary succession.
Hepatophyta
Common Name: Liverwort
Scientific Name: Hepatophyta
Group: Seedless nonvascular
Characteristics: Thallose or leafy form, 2 mm to 25 cm
Habitat: Damp environments
Reproduce: Eggs are produced on umbrella-like structures. They rely on free-standing water to
allow their sperm to swim to and fertilize eggs.
Examples: Porella platyphylla, Conocephalum conicum, and Riccia fluitans
Interesting Info: Liverwort refers to thallose liverworts, which look like the lobes of a liver flat on
the ground.
Anthocerophyta
Common Name: Hornworts
Scientific Name: Anthocerophyta
Group: Seedless nonvascular
Characteristics: grow low to the ground, flat body with little green horns
Habitat: Tropical forests and along streams
Reproduce: Little green horns rising above the flat plant body produces spores. They rely
on free-standing water to allow their sperm to swim to and fertilize eggs.
Examples: Dendroceros crispus, Ceratophyllum demersum, and Schistochila
appendiculata
Interesting Info: New Zealand has the world’s longest leafy liverwort.
Lycophyta
Common Name: Club Mosses
Scientific Name: Lycophyta
Group: Seedless vascular
Characteristics: small, lack flowers, and grow off the ground
Habitat: Lowland mixed forest and boggy areas
Reproduce: Sexually by spores. Depends on water for reproduction.
Examples: Lycopodium cernuum, Lycopodium volubile, and Lycopodium laterale
Interesting Info: Not true mosses. They belong to the oldest living group of vascular
plants.
Pterophyta
Common Name: Ferns
Scientific Name: Pterophyta
Group: Seedless vascular
Characteristics: Lack true roots and leaves and have large leaves called fronds
Habitat: Tropics and subtropics
Reproduce: Depends on water for reproduction.
Examples: Staghorn Fern, Boston Fern, and Lady Fern
Interesting Info: Has 12,000 species today,
Cycadophyta
Common Name: Cycads
Scientific Name: Cycadophyta
Group: Cone-bearing seed
Characteristics: Look like palm trees and large leaves
Habitat: Tropical areas in Americas, Asia, Africa, and Australia
Reproduce: Reproduce without free-standing water. Seeds nourish and protect plant
embryos. Seeds allow plants to disperse to new places.
Examples: Sea Sago, Royal Sago, and King Sago
Interesting Info: Many cycads species are endangered due to their slow growth and loss
of habitat
Ginkophyta
Common Name: Ginkgo
Scientific Name: Ginkgophyta
Group: Cone-bearing seed
Characteristics: Fan-shaped leaves and branches with numerous shoots
Habitat: China
Reproduce: Reproduce without free-standing water. Seeds nourish and protect plant embryos.
Seeds allow plants to disperse to new places.
Example: Ginko biloba
Interesting Info: The oldest loving species of seed plants. It's used in urban landscaping.
Coniferophyta
Common Name: Conifers
Scientific Name: Coniferophyta
Group: Cone-bearing seed
Characteristics: needlelike leaves
Habitat: High altitudes, mountains
Reproduce: Reproduce without free-standing water. Seeds nourish and protect plant embryos.
Seeds allow plants to disperse to new places.
Examples: Pines, redwood, spruce, cedar, fir, and juniper
Interesting Info: They supply most of the timber for paper, cardboard, housing lumber, and
plywood
Anthophyta
Common Name: Flowering plants
Scientific Name: Anthophyta
Group: Flowering seed
Characteristics: broad leaves, have pollen, and has flower
Habitat: Adapt to most environments
Reproduce: Flowers protect a plants gametes and fertilized eggs. Fruit is the mature ovary
of a flower.
Examples: Prickly pear, Water lily, Dwarf mistletoe
Interesting Info: They comprise about 90 percent of the Kingdom Plantae
