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,
Kefersteinia (plant) Kefersteinia (plant) Kefersteinia is a genus of flowering plants from the orchid family, Orchidaceae. It has about 40-50 species, widespread across much of Latin America. The genus was named for Keferstein of Kröllwitz, an orchidologist. Plants of the genus are small sympodial orchids closely related to "Chondrorhyncha", growing tall. Orchids have a long or short rhizome and lack pseudobulbs. Linear to lanceolate leaves form a fan shape, articulated to a sheath at their base. Single flowered inflorescences rise from the base or between leaves, often multiple at a time. Flowers are thin and translucent, with similar petals and sepals. The
