Edible plant stems are one part of plants that are eaten by humans. Most plants are made up of stems, roots, leaves, flowers, and produce fruits containing seeds. Humans most commonly eat the seeds, fruit, flowers, leaves, roots, and stems (e.g. [asparagus] of many plants. There are also a few edible petioles such as celery or rhubarb.
Cymopterus multinervatus is a species of flowering plant in the carrot family known by the common name purplenerve springparsley. It is a perennial herb native to the southwestern United States, including the desert regions. It is stemless, producing leaves and inflorescence at ground level from a taproot. The leaves are erect on petioles of a few centimeters in length, with a fleshy blade dissected into waxy multilobed leaflets. The inflorescence arises on a stout purple or greenish peduncle up to about 14 centimeters tall. At the top is a rounded cluster of purple flowers sheathed in purple-veined bracts.
In botany, a scape is a peduncle arising from a subterranean or very compressed stem, with the lower internodes very long and hence few or no bracts except the part near the rachis or receptacle. Typically it takes the form of a long, leafless flowering stem rising directly from a bulb, rhizome, or similar subterranean or underwater structure.
Pinguicula moranensis is a perennial rosette-forming insectivorous herb native to Mexico and Guatemala. A species of butterwort, it forms summer rosettes of flat, succulent leaves up to 10 centimeters (4 in) long, which are covered in mucilaginous (sticky) glands that attract, trap, and digest arthropod prey. Nutrients derived from the prey are used to supplement the nutrient-poor substrate that the plant grows in. In the winter the plant forms a non-carnivorous rosette of small, fleshy leaves that conserves energy while food and moisture supplies are low. Single pink, purple, or violet flowers appear twice a year on upright stalks up to 25 centimeters long.
Nekemias arborea, commonly known as pepper vine, is native to the Southeastern United States, Texas, and New Mexico. It spreads rapidly, climbing up trees and bushes. It prefers moist soils such as stream banks, and disturbed areas.
Cymopterus purpurascens is a species of flowering plant in the carrot family known by the common name widewing springparsley. It is native to much of the western United States, including the desert regions. It is a perennial herb, often stemless, producing leaves and inflorescence from ground level or from a fibrous basal stalk. The waxy, fleshy leaves have blades divided into multilobed leaflets and are borne on short petioles. The inflorescence is a rounded cluster of flowers held on a peduncle which may be erect and several centimeters tall or nearly nonexistent. The purple flowers are sheathed in dark-veined white bracts.
Cymopterus aboriginum is a species of flowering plant in the carrot family known by the common name Indian springparsley.
Cymopterus gilmanii is a species of flowering plant in the carrot family known by the common name Gilman's springparsley.
Dudleya farinosa is a species of succulent plant in the family Crassulaceae known by several common names, including bluff lettuce, powdery liveforever, and powdery dudleya. A coastal plant of northern California and southern Oregon, it is typically found on oceanic bluffs just directly above the reach of the waves. Its appearance is characterized by lotus-like rosettes of beveled leaves, and in summer the plant erects a tall pink to red stem densely covered in foliage, topped with branches adorned with pale yellow flowers. The green or white rosettes of this plant can be seen covering stretches of rocky coast and nearby islets.
Sclerosperma is a monoecious genus of flowering plant in the palm family found in Africa where three species are known. Having no obvious relatives, it does resemble the Madagascar native Marojejya though a detailed study of Madagascar's palms is required to determine if any true relationship exists. The lack of relatives, and its interesting qualities, indicate, at one time, the existence of a diverse African palm flora. The name is from two Greek words meaning "hard" and "seed".
Sommieria is a monotypic genus of flowering plant in the palm family endemic to New Guinea where they grow in rain forest understory. The sole species is Sommieria leucophylla. They resemble the Asterogyne palms but are most closely related to those members of Heterospathe with short stems and sparsely branched inlforescences. The name honors Stephen Sommier, European botanist.
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue. The stem can also be called halm or haulm.
Ipomoea heptaphylla, sometimes known as Wright's morning glory in the United States, is a species of morning glory. It is incorrectly classified as I. wrightii in American publications, but is incorrectly known as I. tenuipes in Africa and India. It is an annual or short-lived perennial vine which climbs using twining stems, and has pink or purple flowers. The leaf shape is somewhat variable, with individuals possessing compound leaves palmately divided into five leaflets, and lanceolate-leaved individuals occurring in neighbouring populations. The name heptaphylla actually means 'seven-leaved'. This plant has a very extensive distribution, from Texas and adjacent states in the southeastern USA to Misiones in northern Argentina, the Greater Antilles of the Caribbean, India, Sri Lanka and East and Southern Africa. Despite its wide distribution it is uncommon throughout its range. The rediscovery of the presence of the species in India after an absence of over half a century was published in 2014. The species appears to favour dry subtropical to tropical habitats.
Microseris elegans is a species of flowering plant in the family Asteraceae known by the common name elegant silverpuffs. It is native to California and Baja California, where it grows in the valleys, foothills, and coastal mountain ranges. Its habitat includes grassland, sometimes near vernal pools, and especially clay soils.
Scoliopus bigelovii is a species of flowering plant in the lily family known by several common names, including California fetid adderstongue, Bigelow's adderstongue, slinkpod, and brownies. It is native to California, where it is known from the Santa Cruz Mountains, parts of the San Francisco Bay Area and North Coast Ranges. It has also been collected just over the border in Oregon. It occurs in old-growth forest in the understory of redwoods. It grows in mossy, moist places, often in shade.
Vancouveria planipetala is a species of flowering plant in the barberry family known by the common names redwood inside-out flower and redwood ivy.
Roscoea cautleyoides is a perennial herbaceous plant occurring in the Sichuan and Yunnan provinces of China. The scientific name is also spelt Roscoea cautleoides. Most members of the ginger family (Zingiberaceae), to which it belongs, are tropical, but R. cautleyoides, like other species of Roscoea, grows in much colder mountainous regions. It is sometimes grown as an ornamental plant in gardens.
Aristolochia contorta, commonly known as northern pipevine, also known as birthwort, is a climbing perennial shrub.
Pandanus drupaceus is a species of plant in the family Pandanaceae, endemic to Mauritius.
Passiflora bogotensis is a climbing plant native to Colombia, in the genus Passiflora. It can also be found in Venezuela.
