Lophophora
Encyclopedia
Lophophora is a genus
of spineless, button-like cacti
native to the southwestern United States
(Texas
and New Mexico
) through Northeast Mexico
and South to Querétaro
in central Mexico.
The species are extremely slow growing, sometimes taking up to thirty years to reach flowering age (at the size of about a golf ball, excluding the root) in the wild. Cultivated specimens grow considerably faster, usually taking between three to ten years to reach from seedling to mature flowering adult. The slow rate of reproduction and over-harvesting by collectors render the species under threat in the wild.

. The name is derived from the two Ancient Greek
words λοφος (lophos, the crest of a hill or helmet) and φορεω (phoreo, to carry). Lophophora has been reported to comprise everything from one species, L. williamsii with varieties, to the four species L. diffusa, L. fricii, L. diffusa ssp. viridescens, and L. williamsii. Most modern authorities consider Lophophora to be a genus of two species, L. diffusa
and L. williamsii. Recent DNA sequencing
studies (Butterworth et al. 2002) have shown that L. diffusa and L. williamsii indeed are distinct species. DNA evidence from the alleged species L. fricii and L. viridescens would allow for more accurate classification.
Below is given a key for the currently accepted species along with the "species" and varieties that must be considered synonymous. Detailed arguments for this classification can be found in Peyote: The Divine Cactus (Anderson 1996, pp. 210-219).
Several people have reported that this cactus is psychoactive if ingested, though the experience is not unlike peyote. This species looks almost identical to peyote, though it is legal to possess in the United States.
. While L. diffusa is known for having psychoactive effects, these effects are described not so much as "visionary", like peyote
, but rather a delirious high such as those associated with the use of Datura
and Belladonna. The stem is used as a spiritual hallucinogen, and is applied topically as a galactogogue, or lactation
aid .
Seedlings grow most rapidly when enclosed in a sealed terrarium environment, having been germinated in trays of shallow sand covered with plastic wrap with several small pin sized holes in the plastic wrapping. This may seem strange for a cactus, but Lophophora seedlings are adapted to germinate and grow during the seasonal monsoons. Plants grown this way can reach 5 cm (2 in) diameter in just over a year and can be removed from their hyper-humid environment and will typically reach flowering size in just under three years.
Lophophora are closely related to the genera Ariocarpus
, Aztekium
, and Obregonia and like its relatives possesses a large taproot system with the majority of the plant's mass underground for water storage. Lophophora is more tolerant of soil types than its relatives, and typically grows in areas which have decomposed limestone
present in the soil. In cultivation, Lophophora does best in a fast draining mineral based soil which is about 2/3 sand. Abundant water is beneficial in the summer months when the temperatures are over 90 degrees and exposed to full sunlight for maximum growth, but must be allowed to dry out completely between waterings. They should also be fertilized twice a year. Over fertilizing will typically result in the Lophophora developing cracks and splitting. At times, some varieties of Lophophora will develop a corky material on the plant body if exposed to pesticides or insecticidal soap. This corky condition will usually heal in a manner very similar to human skin if the plants are exposed to full sunlight.
When overwatered during the winter months, Lophophora plants can succumb to soil-borne fungus infections. Pyroclay (Pyrophyllitic Clay) is an effective preventative and soil additive which increases their resistance. Due to the large amount of alkaloids produced by this plant and stored in its tissues, Lophophora roots (not the green part of the plant above ground) are highly alkaline and are known to harbor Clostridium botulinum
bacteria and should not be used for human consumption and have been found to contain botulinum toxin
in nature.
Lophophora are free flowering in cultivation and although they can withstand temperatures into the 10's during winter they do not require a cold shocking in order to initiate flowering. Lophophora plants in habitat typically flower after rainstorms which have been preceded by a period of high temperatures and dry conditions. Plants in cultivation can be encouraged to flower by subjecting the plants to high temperatures, direct sunlight, and withholding water for several weeks, then watering heavily which will usually initiate flowering.

Cultivation
Lophophora species easily adapt to cultivation. Although a cactus, most of the range this genus is found is within a subtropical climate for some portion of the year. In habitat plants in this genus are subject to seasonal monsoons within their range and the plants live in areas where they may be underwater for several weeks during heavy rains and can tolerate a lot of water when the temperatures are above 100 degrees. These plants are heat adapted and grow rapidly when exposed to temperatures of 110 to 120 degrees and watered heavily in the summer. In habitat, plants from areas which experience seasonal monsoons and high temperatures such as southern Texas can reach flowering size in five years. During the fall and winter months, the plants receive almost no water in habitat and are subjected to temperatures which can drop into the upper 20's during the winter. The plants should not be watered during the winter rest or watered sparingly when they begin to shrink and wrinkle only enough to keep them turgid. Lophophora plants must be kept completely dry if they are subjected to temperatures below 40 degrees as watering plants and subjecting them to below freezing temperatures will typically result in the death of the plant.Seedlings grow most rapidly when enclosed in a sealed terrarium environment, having been germinated in trays of shallow sand covered with plastic wrap with several small pin sized holes in the plastic wrapping. This may seem strange for a cactus, but Lophophora seedlings are adapted to germinate and grow during the seasonal monsoons.
