12 Foundations of Biology — Organisms to Ecosystems Trees and Shrubs: This is a list of both native and non-native trees and shrubs. 1. Maidenhair tree/ Ginkgo biloba (Ginkgoaceae). This is a gymnosperm, not an angiosperm. The Ginkgo tree is easy to identify because of the unique shape of its leaves and the rank odor of its seeds. Despite its broadleaf character, this plant is more closely related to pine and spruce trees than F owering broadleaved plants. This plant is considered to be a “living fossil” and was thought to be extinct until it was found in Japan in the 17th century. Chinese literature refers to the gingko tree as early as the 11th century. 2. Yew/ Taxus canadensis (Taxaceae). The yew is a gymnosperm s with seeds that look like fruits, but unlike edible ginkgo seeds, yew seeds are poisonous and contain a dangerous heart depressant. 3. American beech/ Fagus grandifolia (±agaceae). The light gray bark of the beech is smooth and resembles an elephant’s knee. Unlike most trees, the beech retains its thin bark even in old age, making it susceptible to fungal infection. 4. White pine/ Pinus strobus (Pinaceae). This is a gymnosperm, s not an angiosperm. If you look closely at the needles on a pine tree, you will notice that they occur in bundles of ² ve. Pines are divided into two groups, soft and hard pines, based on their fascicle (bundle) number. The soft pines contain ² ve needles to a fascicle, the hard pines contain two or three needles per fascicle. 5. Southern Magnolia/ Magnolia grandi± ora (Magnoliaceae). Magnolias have a great ornamental value, feature showy F owers, and are relatively free from insect diseases. 6. Tulip tree/ Liriodendron tulipifera (Magnoliaceae). It is the leaf’s shape (like a tulip) that most easily identi² es this member of the Magnolia family, although the name tulip actually comes from the tulip-like F owers that grow on this tree.
