Question: Are Clover and Echinopsis both types of cactus?

Context paragraphs:
Echinopsis: Echinopsis is a large genus of cacti native to South America, sometimes known as hedgehog cactus, sea-urchin cactus or Easter lily cactus.  One small species, "E. chamaecereus", is known as the peanut cactus.  The 128 species range from large and treelike types to small globose cacti.  The name derives from "echinos" hedgehog or sea urchin, and "opsis" appearance, a reference to these plants' dense coverings of spines.

Psychoactive cactus: Many cacti are known to be psychoactive, containing phenethylamine alkaloids such as mescaline However, the two main ritualistic (folkloric) genera are "Echinopsis", of which the most psychoactive species is the San Pedro cactus ("Echinopsis pachanoi", syn.  "Trichocereus pachanoi"), and "Lophophora", with peyote ("Lophophora williamsii") being the most psychoactive species.  Several other species pertaining to other genera are also psychoactive, though not always used with a ritualistic intent.

Echinopsis scopulicola: Echinopsis scopulicola is a type of cactus native to Bolivia, which contains psychedelic compounds.  Many claim this species contains mescaline, which was until recently unconfirmed due to the lack of official research, but a study published in September 2010 by the International Society for Ethnopharmacology placed it in the top third of the results for their samples.  This included 14 taxa/cultivars of the subgenus Trichocereus of the genus Echinopsis, with Scopulicola noted to contain 0.82% mescaline/dry weight in the outer green layer.

Echinopsis pachanoi: Echinopsis pachanoi (syn.  Trichocereus pachanoi) — known as San Pedro cactus — is a fast-growing columnar cactus native to the Andes Mountains at 2000 – in altitude.  It is found in Argentina, Bolivia, Chile, Ecuador and Peru, and it is cultivated in other parts of the world.  Uses for it include traditional medicine and traditional veterinary medicine, and it is widely grown as an ornamental cactus.  It has been used for healing and religious divination in the Andes Mountains region for over 3,000 years.  It is sometimes confused with its close relative "Echinopsis peruviana" (Peruvian torch cactus).

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).

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.

Echinopsis silvestrii: Echinopsis silvestrii is a species of cactus from Argentina.  It should not be confused with "Echinopsis chamaecereus", formerly known as "Chamaecereus silvestrii".

Echinopsis peruviana: Echinopsis peruviana (syn.  Trichocereus peruvianus), Peruvian torch cactus, is a fast-growing columnar cactus native to the western slope of the Andes in Peru, between about 2000 - above sea level.  It contains the psychoactive alkaloid mescaline as well as other alkaloids, although reported levels vary considerably and do not approach the concentrations found in "Echinopsis pachanoi".

Achuma (Bolivia): Achuma (Aymara for a large cactus plant, "(Echinopsis lageniformis)", "(Echinopsis pachanoi)" or other species, also the name of a drink, also spelled "Achoma") is a mountain in the northern part of the Kimsa Cruz mountain range in the Bolivian Andes, about 4960 m high.  It is situated in the La Paz Department, Loayza Province, Cairoma Municipality.  The peaks of Achuma lie north-west to north of the mountain Taruja Umaña and south of Janq'u Willk'i.  There are two small lakes north of the mountain.  They are named Allqa Quta ("two-colored lake", "Alca Kkota") and Ch'iyar Quta ("black lake", "Chiar Kkota").

Echinopsis chamaecereus: Echinopsis chamaecereus is a species of cactus from Argentina.  Synonyms include "Chamaecereus silvestrii" and "Lobivia silvestrii".  It has been called the "peanut cactus", although other authors use this name only for "Echinopsis silvestrii", a different species.
