Plant morphology share the same basic structure and development as leaves in other plants, and therefore cactus spines are homologous to leaves as well. This aspect of plant morphology overlaps with the study of plant evolution and paleobotany. Secondly, plant morphology observes both the vegetative (somatic) structures of plants, as well as the reproductive structures. The vegetative structures of vascular plants includes the study of the shoot system, composed of stems and leaves, as well as the root system. The reproductive structures are more varied, and are usually specific to a particular group of plants, such as flowers and seeds, fern sori,
Comptonia (plant) Comptonia (plant) Comptonia is a monotypic genus (containing only Comptonia peregrina) in the family Myricaceae, order Fagales. It is native to eastern North America, from southern Quebec south to the extreme north of Georgia, and west to Minnesota. The common name is sweetfern or sweet-fern, a confusing name as it is not a fern. It is a deciduous shrub, growing to tall. The leaves of the plant are linear to lanceolate, long and broad, with a modified dentate, pinnately lobed margin; they give off a sweet odor, especially when crushed. The flowers are imperfect, meaning that no one flower has
