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

Context paragraphs:
Salvia longispicata: Salvia longispicata is a perennial shrub native to southwestern Mexico, growing between 1000 and elevation.  The specific epithet "longispicata" gives the impression that the plant has "long spikes", but instead refers to the many projecting clusters of short flowering spikes that resemble small ears of corn.

Phrynosomimus: Phrynosomimus is an extinct genus of iguanian lizard from the Late Cretaceous of Mongolia belonging to the extinct family Priscagamidae.  The type species Phrynosomimus asper was named in 1996.  Fossils have been found in the Barun Goyot and Djadochta formations and include several complete skulls.  "Phrynosomimus" has a short, triangular skull with bony spikes projecting from the back, stemming from the squamosal and parietal bones.  These spikes give it a similar appearance to the modern horned lizard "Phrynosoma" and inspire its name, which means ""Phrynosoma" mimic".  Like other priscagamids it has an acrodont dentition, meaning that its teeth grow from the margins of the jaws rather than their inner surfaces, as is the case for the pleurodont dentitions of most lizards.

Heterodera medicaginis: Heterodera medicaginis (Alfalfa cyst nematode) is a plant pathogenic nematode which is cited as an invasive species.  It is closely allied to "Heterodera daverti", "H. glycines" and "H. sonchophila" in the H. schachtii-group.  The only known host plant of this obligate parasite is the important crop alfalfa or lucerne, "Medicago sativa".

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.

Uromyces medicaginis: Uromyces striatus is a plant pathogen causing rust in "Medicago".  Alfalfa ("Medicago sativa") rust caused by "Uromyces striatus" is an important disease in many areas and is damaging to alfalfa grown for seed.

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.

Carex obnupta: Carex obnupta is a species of sedge known by the common name slough sedge.  It is native to western North America from British Columbia to California where it grows abundantly in wet, often saline habitat such as wetlands.  The plant produces upright, angled stems approaching 1.2 meters in maximum height, growing in beds or colonies from rhizome networks.  The inflorescence is a cluster of flower spikes accompanied by a long leaflike bract.  The pistillate spikes and sometimes the staminate spikes dangle on peduncles.  The fruit is coated by a hard, tough, shiny perigynium which is generally dark in color.

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".

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.

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.
