Lysimachia latifolia (broadleaf starflower) is a perennial herbaceous plant of the ground layer of forests in western North America. Herbaceous plants are vascular plants that have no persistent woody stems above ground. [1] [2] This broad category of plants includes many perennials, and nearly all annuals and biennials. [3]
Herbaceous: Non woody stems which die at the end of the growing season. Internode: An interval between two successive nodes. It possesses the ability to elongate, either from its base or from its extremity depending on the species.

Most vines are flowering plants. These may be divided into woody vines or lianas, such as akebia wisteria, kiwifruit, and common ivy, and herbaceous (nonwoody) vines, such as morning glory. One odd group of vining plants is the fern genus Lygodium, called climbing ferns. [10] The stem does not climb, but rather the fronds (leaves) do.
In herbaceous plants, it occurs in the vascular bundles which are often arranged like beads on a necklace forming an interrupted ring inside the stem. In woody plants, it forms a cylinder of unspecialized meristem cells, as a continuous ring from which the new tissues are grown.
Bark is present only on woody plants - herbaceous plants and stems of young plants lack bark. Tree cross section diagram. From the outside to the inside of a mature woody stem, the layers include the following: [20]
