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,
Hyacinth (plant) bulbs, each producing around four to six linear leaves and one to three spikes or racemes of flowers. In the wild species, the flowers are widely spaced with as few as two per raceme in "H. litwinovii" and typically six to eight in "H. orientalis", which grows to a height of . Cultivars of "H. orientalis" have much denser flower spikes and are generally more robust. The genus name "Hyacinthus" was attributed to Joseph Pitton de Tournefort when used by Carl Linnaeus in 1753. It is derived from a Greek name used for a plant by Homer, (), the flowers
