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,
Nolina microcarpa a rosette of many narrow leaves each up to long but only wide. The grasslike leaf blades are thick, rough, and serrated. There is no aboveground stem; the leaves grow from a woody underground caudex. When the plant flowers it produces a scape up to tall. The inflorescence is a panicle of flowers with tiny white tepals. The species is dioecious, with male and female flowers on separate plants; occasionally there are flowers with both male and female parts functional. The fruit is a papery, three-sided capsule about half a centimeter long and wide. This plant grows in dry habitat
