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,
Fabiana (plant) Fabiana (plant) Fabiana is a genus of flowering plants in the nightshade family, native to dry slopes in western South America. They are evergreen shrubs or subshrubs, with needle-like leaves and profuse tiny tubular flowers in summer. The common name is false heath because the leaves superficially resemble those of the distantly related heaths. The species "F. imbricata" is cultivated as a common horticultural plant and a common herbarium specimen. Members of the genus grow within 16◦ and 51◦ latitude in the arid mountainous regions of South America between 1000–4900 m above sea level. The "Fabiana" genus has been studied
