Study Notes
Plant Terminology Overview
- Terminology relates to plant anatomy and classification.
- Important to understand leaf morphology, plant habits, and life cycles.
Clintonia uniflora
- Leaf margin is smooth and entire.
- Leaf venation is parallel, characteristic of monocots.
- Classified as a eudicot (not a monocot).
Rubus parviflorus
- This plant typically has a biennial life span.
- Habit is erect and may become woody over time.
- Leaf shape is palmately lobed, resembling a hand with fingers.
Sambucus cerulea
- Commonly known as blue elderberry.
- Leaf complexity is compound, featuring multiple leaflets.
- Habit is often shrub-like, reaching several meters in height.
Galium triflorum
- Leaf arrangement is whorled, with leaves around the stem.
- Prostrate growth means it grows horizontally along the ground.
- Trichomes are hair-like structures that can serve various functions, including protection.
Pinus ponderosa
- This tree falls under the category of gymnosperms, which produce seeds without flowers.
- Needles are found in bundles of three.
- Needles are long and flexible, with a distinctive yellowish-green color.
Corylus cornuta
- Leaf margin is serrated, characterized by sharp notches.
- Leaf venation is palmate, with veins radiating from a central point.
- Leaf arrangement is alternate, with leaves positioned staggered along the stem.
Centaurea stoebe
- This plant is often classified as a biennial, completing its life cycle over two years.
- Plant habit is erect and branching, frequently reaching heights of 1 meter.
- Described as invasive, meaning it spreads aggressively and outcompetes native species.
Symphoricarpos albus
- Leaf arrangement is opposite, with pairs of leaves at each node.
- Leaf complexity is simple, featuring single leaf structures.
- Leaf shape is broadly oval to elliptic, with entire margins.
Prunus virginiana
- Leaf arrangement is alternate, with leaves spaced along the stem.
- Leaf complexity is simple, consisting of a single leaf blade.
- Lenticels are small, raised pores on stems helping with gas exchange.
Populus tremuloides
- This species is an angiosperm, characterized by flowering and seed production.
- The petiole is flattened, allowing leaves to flutter in the wind for maximum sunlight.
- Dioicous means this plant has separate male and female individuals for reproduction.
