Want to learn more about plants in both the aquatic and terrestrial areas of Oregon? This page provides a comprehensive and alphabetical list of the plants currently catalogued on the Oceanscape Network. Check back frequently as this list will change and grow over time.

Angiosperms

Angiosperms are plants which produce flowers and seeds which are enclosed within the female reproductive organs. This is a very large group of plants and encompasses grasses, herbs, shrubs and many types of trees. Angiosperms are the most advanced form of plant life on Earth.

American Beach Grass | Bigleaf Maple | California Black Oak | Coastal Strawberry | Columbia Lily | Common Camas | Common Evening Primrose | Devil’s Club | Early Blue Violet | European Beach Grass | Evergreen Huckleberry | Farewell To Spring | Gorse Weed | Hairy Manzanita | Lewis’s Monkeyflower | Marine Eelgrass | Oregon Ash | Oregon Grape | Oregon Iris | Oregon White Oak | Ox-Eyed Daisy | Pacific Dogwood | Pacific Rhododendron | Pickleweed | Red Alder | Red Columbine | Salal | Salmonberry | Sea Rocket | Silverweed | Small Cranberry | Vine Maple | Western Skunk Cabbage

Bryophytes

Bryophytes are a type of simple plant which include mosses and liverworts. These types of plants lack flowers and roots and reproduce by releasing spores into the air which are carried to other places on the wind. These are the most primitive forms of plant life on Earth.

NONE CURRENTLY LISTED.

Charophytes (Green Algae)

These fresh water aquatic plants were some of the first to develop on Earth, with fossilized examples extending back as far as the Silurian Period or 443 to 419 million years ago. Many species of these Charophytes are now extinct but modern examples are common in rivers, lakes, estuaries, streams and wetlands. Charophytes include green algae and stoneworts.

Sea Lettuce

Fungi

Fungi are a group of single celled and multi-cellular organisms. This abundant group of plants can include mushrooms, toadstools, molds, yeasts and other species which develop within soils, on decomposing organic matter or in symbiosis with other plant species. Fungi reproduce through the release of spores.

NONE CURRENTLY LISTED.

Gymnosperms

Gymnosperms produce seeds in an unprotected ovary, cone or fruit. This differentiates them from Angiosperms where the seeds are protected within the body of the plant. Gymnosperms include conifers, cycads and ginkgo.

Coast Redwood | Douglas-fir | Port Orford Cedar | Shore Pine | Sitka Spruce | Western Hemlock | Western Redcedar

Rhodophyta (Red Algae)

A very ancient form a plant life, Rhodophytes include most marine algae including sea weeds. There are currently 6,000 known species of these plants, most of which occur in the ocean with a handful of freshwater species. These plants reproduce sexually and can be microscopic or form large colonies.

Encrusting Coralline Algae

Phaeophyta (Brown Algae)

This is the largest and most complex marine algae group on Earth, comprising some 1,800 known species. Like terrestrial plants, Brown Algae uses chlorophyll used to absorb sunlight needed for photosynthesis. Brown Algae includes many types of kelp and sargassum.

Bull Kelp | Feather Boa Kelp | Sargassum | Sea Palm

Vascular Plants

Common throughout the forests of the Pacific Northwest, vascular plants include all ferns and are non-flowering plants with large, feather-like leaves. An internal system of vessels conducts water and nutrients throughout these plants. They can reproduce both sexually and through the release of spores.

Bracken Fern | Western Sword Fern |
