Question: Which plant has more spikes projecting from its stems: Fouquieria or Alfalfa?

full_context: Document 1: Fockea edulis: Fockea edulis is a species of plant in the Apocynaceae family that is native to South Africa and Namibia. A common name is Hottentot bread due to the milky, somewhat sweetish flavour of the edible root which is sometimes gathered from the wild for local use. The plant's latex is said to be poisonous. In Afrikaans the plant is called Bergbaroe, Bergkambroo, Kambaroo, Kambroo, Kambro, or Hotnotswaatlemoen. In Khoi it is called !Koo, !Ku, or !Kuu. A semi-deciduous perennial caudiciform with fat, twisted grey roots, it grows in warmer drier areas, dry savannah and rockery. In the wild, the caudex is partially or totally buried and tends to grow faster this way up to 60 cm in diameter. Fockeas are dioecious, so a male plant and a female plant are needed to produce seeds. The flowers are whitish-green, not very showy but lightly scented, small (0.6-1.5 cm wide) vygie-like flowers surrounded by a large, thick, spider-like calyx. The flowers are pollinated by fruit flies. The plant produces grey-greenish pods. The thin vine branches may reach a length of up to 4 meters, and climb on any type of available support. The leaves are green, entire and oblong. Although it shows decreased activity in the January – April period, it never goes into complete dormancy and always carries some leaves. Plants cannot tolerate more than occasional light frosts with temperatures dropping as low as -2°C. This species is of easy cultivation and hardy when kept reasonably dry and watered only enough to keep the tuber from shriveling.
Document 2: Oxystylis: Oxystylis is a monotypic genus of flowering plants currently considered a part of the cleome family containing the single species Oxystylis lutea, which is known by the common name spiny caper. It is native to the Mojave Desert straddling the border between California and Nevada. It grows in rocky and sandy desert habitat, often on alkaline soils. This is an annual herb producing an erect, branching stem which may reach 1.5 meters in height. The leaf is made up of three thick, firm leaflets 2 to 6 centimeters long, borne on a stout, straight petiole. The inflorescence is a dense head of flowers clustered about the stem at the leaf axils, each flower with four small yellow petals. The fruit is a small white or purple nutlet bearing the spine-like remnant of the flower receptacle.
Document 3: Fouquieria: Fouquieria is a genus of 11 species of desert plants, the sole genus in the family Fouquieriaceae. The genus includes the ocotillo ("F. splendens") and the boojum tree or cirio ("F. columnaris"). They have semisucculent stems with thinner spikes projecting from them, with leaves on the bases spikes. They are unrelated to cacti and do not look much like them; their stems are proportionately thinner than cactus stems and their leaves are larger.
Document 4: Euphorbia: Euphorbia is a very large and diverse genus of flowering plants, commonly called spurge, in the spurge family (Euphorbiaceae). "Euphorbia" is sometimes used in ordinary English to collectively refer to all members of Euphorbiaceae (in deference to the type genus), not just to members of the genus. Some euphorbias are commercially widely available, such as poinsettias at Christmas. Some are commonly cultivated as ornamentals, or collected and highly valued for the aesthetic appearance of their unique floral structures, such as the crown of thorns plant. Euphorbias from the deserts of Southern Africa and Madagascar have evolved physical characteristics and forms similar to cacti of North and South America, so they (along with various other kinds of plants) are often incorrectly referred to as "cacti". Some are used as ornamentals in landscaping, because of beautiful or striking overall forms, and drought and heat tolerance.
Document 5: Medicago falcata: Medicago falcata is a plant species of the genus "Medicago". It is native to the Mediterranean basin, but is found throughout the world. It forms a symbiotic relationship with the bacterium "Sinorhizobium meliloti", which is capable of nitrogen fixation. Its common names include yellow lucerne, sickle alfalfa, yellow-flowered alfalfa, yellow alfalfa, sickle medick and yellow medick.
Document 6: Stillingia spinulosa: Stillingia spinulosa is a species of flowering plant in the euphorb family known by the common name annual toothleaf. It is native to the southwestern United States where it occurs in the creosote scrub of the deserts. It is an annual or perennial herb producing a clump of thick, leafy stems approaching a meter in maximum height. The alternately arranged leaves have shiny pointed oval blades 2 to 4 centimeters long and up to 1.2 centimeters wide which are lined with sharp teeth. The inflorescence is a stout spike of flowers 1 to 2 centimeters long. The plant is monoecious, and each spike has several male flowers at the tip and 1 or 2 fruit-bearing female flowers below these. Neither type of flower has petals. The ovary of the female flower develops into a three-lobed greenish capsule about half a centimeter wide. There is a tiny rough-surfaced seed in each of the three chambers of the fruit.
Document 7: Schlumbergera: Schlumbergera is a small genus of cacti with six species found in the coastal mountains of south-eastern Brazil. Plants grow on trees or rocks in habitats that are generally shady with high humidity, and can be quite different in appearance from their desert-dwelling cousins. Most species of "Schlumbergera" have stems which resemble leaf-like pads joined one to the other and flowers which appear from areoles at the joints and tips of the stems. Two species have cylindrical stems more similar to other cacti. In Brazil, the genus is referred to as "Flor de Maio " (May flower), reflecting the period in which they flower in the Southern Hemisphere.
Document 8: Clover: Clover or trefoil are common names for plants of the genus Trifolium (Latin, "tres" "three" + "folium" "leaf"), consisting of about 300 species of plants in the leguminous pea family Fabaceae. The genus has a cosmopolitan distribution; the highest diversity is found in the temperate Northern Hemisphere, but many species also occur in South America and Africa, including at high altitudes on mountains in the tropics. They are small annual, biennial, or short-lived perennial herbaceous plants. Clover can be evergreen. The leaves are trifoliate (rarely quatrefoiled (Four-leaf clover), cinquefoil, or septfoil), with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers; the small, few-seeded pods are enclosed in the calyx. Other closely related genera often called clovers include "Melilotus" (sweet clover) and "Medicago" (alfalfa or Calvary clover).
Document 9: Alfalfa: Alfalfa , Medicago sativa also called lucerne, is a perennial flowering plant in the pea family Fabaceae cultivated as an important forage crop in many countries around the world. It is used for grazing, hay, and silage, as well as a green manure and cover crop. The name alfalfa is used in North America. The name lucerne is the more commonly used name in the United Kingdom, South Africa, Australia, and New Zealand. The plant superficially resembles clover (a cousin in the same family), especially while young, when trifoliate leaves comprising round leaflets predominate. Later in maturity, leaflets are elongated. It has clusters of small purple flowers followed by fruits spiralled in 2 to 3 turns containing 10–20 seeds. Alfalfa is native to warmer temperate climates. It has been cultivated as livestock fodder since at least the era of the ancient Greeks and Romans. Alfalfa sprouts are a common ingredient in dishes made in South Indian cuisine.
Document 10: Arachis: Arachis is a genus of about 70 species of annual and perennial flowering plants in the pea family (Fabaceae), native to South America, and was recently assigned to the informal monophyletic "Pterocarpus" clade of the Dalbergieae. At least one species, the peanut ("Arachis hypogaea"), is a major food crop species of global importance; some of the other species are cultivated for food to a small extent in South America. Other species such as "A. pintoi" are cultivated worldwide as forage and soil conditioner plants, with the leaves providing high-protein feed for grazing livestock and a nitrogen source in agroforestry and permaculture systems.
Document 11: Cuscuta approximata: Cuscuta approximata is a species of dodder known by the common name alfalfa dodder. It is native to Eurasia and Africa, but it is also found in North America, where it is an introduced species and uncommon noxious weed. It is a parasitic vine which climbs other plants and takes nutrition directly from them via a haustorium. The dodder resembles a pile of light yellow to orange-red straw wrapped tightly around its host plant. It is mostly stem; the leaves are reduced to scales on the stem's surface, since they are not needed for photosynthesis while the dodder is obtaining nutrients from its host. It bears clusters of tiny yellowish bell-shaped flowers which are only about 3 millimeters wide. The dodder reproduces by seed, with each plant capable of producing over 10,000 seeds at once. This plant is a weed of alfalfa, clover, and tomatoes, as well as other crop plants and native flora. This species is sometimes treated as a subspecies of "Cuscuta epithymum".
Document 12: Astragalus: Astragalus is a large genus of about 3,000 species of herbs and small shrubs, belonging to the legume family Fabaceae and the subfamily Faboideae. It is the largest genus of plants in terms of described species. The genus is native to temperate regions of the Northern Hemisphere. Common names include milkvetch (most species), locoweed (in North America, some species) and goat's-thorn ("A. gummifer", "A. tragacanthus"). Some pale-flowered vetches are similar in appearance, but vetches are more vine-like.
Document 13: Peucephyllum: Peucephyllum is a monotypic genus of flowering plants containing the single species Peucephyllum schottii. Its common names include pygmy cedar, Schott's pygmy cedar, desert fir, and desert pine. It is not a cedar, fir, or pine, but a member of the aster family, Asteraceae. It is a leafy evergreen shrub with glandular, resinous foliage. It flowers in yellow flower heads which have only disc florets. The fruits are woody, bristly seeds with a pappus. This plant is native to the deserts of Arizona, California, Nevada, and Utah in the United States and Baja California and Sonora in northern Mexico.
Document 14: Trifolium repens: Trifolium repens, the white clover (also known as Dutch clover, Ladino clover, or Ladino), is a herbaceous perennial plant in the bean family Fabaceae (Previously referred to as Leguminosae). It is native to Europe and central Asia. One of the most widely cultivated types of clover, it has been widely introduced worldwide as a forage crop, and is now also common in most grassy areas (lawns and gardens) of North America and New Zealand. The species includes varieties often classed as small, intermediate and large, according to height, which reflects petiole length. The term “white clover” is applied to the species in general, “Dutch clover” is often applied to intermediate varieties (but sometimes to smaller varieties), and “ladino clover” is applied to large varieties.
Document 15: Adelphocoris lineolatus: Adelphocoris lineolatus, is commonly known as the Lucerne bug or the alfalfa plant bug, and belongs to the family Miridae. It is an agricultural pest causing vast amounts of damage to numerous crops, but primarily to alfalfa crops around the globe.
