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,
Eucharis (plant) Eucharis (plant) Eucharis is a genus of about 15-20 species of Neotropical plants in the Amaryllis family, native to Central America and South America, from Guatemala south to Bolivia. Some species have become naturalized in Mexico, the West Indies, and scattered tropical islands. The English name Amazon lily is sometimes used for all species in the genus (as well as other genera), but is particularly used for "Eucharis amazonica" and "Eucharis" × "grandiflora", which are often confused. "Eucharis" is a perennial with a bulb in diameter. The broad-stalked leaves are long and broad. The large showy white flowers are borne
