Lab #3

This lab we walked around campus and identified various trees, plants, and shrubs. Also one hallucinogenic plant that people die from.


Trees:
Sycamore(Platanus Occidentalis)- An American sycamore tree can often be easily distinguished from other trees by its mottled exfoliating bark, which flakes off in great irregular masses, leaving the surface mottled, and greenish-white, gray and brown.

Crape Myrtle(Lagerstroemia)-Most species of Lagerstroemia have sinewy, fluted stems and branches with a mottled appearance that arises from having bark that sheds throughout the year. 

Ginkgo Tree(Ginkgo Biloba)-The tree is widely cultivated and introduced, since an early period in human history, and has various uses as a food and traditional medicine.

 Shrubs:


Angel's Trumpet(Brugmansia)-Brugmansia are long-lived, woody trees or bushes, with pendulous, not erect, flowers, that have no spines on their fruit

Rhododendron ( Rhododendron maximum)-R. maximum is an evergreen shrub growing to 4 m (13 ft), rarely 10 m (33 ft), tall. The leaves are 9-19 cm (3-8 in) long and 2-4 cm (0.75-1.5 in) broad. The flowers are 2.5-3 cm (1 in) diameter, white, pink or pale purple, often with small greenish-yellow spots.

Hydrangea(Hydrangea Macriohylla)- In climates where hydrangea flowers, place in a mixed shrub border or at the back of a flower bed. Its rich foliage and large size make it a wonderful background for white or light colored flowers, even tall growing perennials and annuals.

Plants:

Mexican Petunia(Ruellia Brittonianiana)- The Mexican petunia is a tender evergreen perennial that forms colonies of stemmy stalks standing 3 ft (0.9 m) in height and of indeterminate width. The strong semi-woody stalks are distinctly vertical in aspect and hold attractive dark green, leaves oppositely at the nodes.

Aloe(aloe vera)-The species is frequently cited as being used in herbal medicine. Many scientific studies on the use of extracts of Aloe vera have been undertaken, some of them conflicting.

Poison Ivey(Toxicodendron radicans)- better known as poison ivy (older synonyms are Rhus toxicodendron and Rhus radicans), is a poisonous North American plant that is well known for its production of urushiol, a clear liquid compound found within the sap of the plant that causes an itching rash in most people who touch it. The plant is not a true ivy (Hedera).
