This photo documentation of plants associated with Lophophora is still in mid-assembly and has much work left to do.
  In the course of field work 2009-present day, a total of seven sites containing Lophophora populations have been explored with this project in mind using kt's camera; three of those were in Tamaulipan thornscrub and four in the Chihuahuan Desert. Those form the present basis of this project. Dr. Terry has examined many more populations in Texas and Mexico that are not presently a part of this floristic assessment.

  At all of those sites just mentioned there were at least one Acacia species, at least one Condalia species, some nature of at least one crust community, an Echinocactus species, at least one Echinocereus species, Jatropha dioica, Koeberlinia spinosa, at least one Leucophyllum species, assorted lichens, a Mammillaria species, at least one Opuntia species, Opuntia leptocaulis and at least one Yucca species.

  Castela texana, a Coryphantha, an Ephedra, Guaiacum, a Prosopis, Schaeferia, a Tiquilia, a Thymophylla and a Viguiera were observed at all but one site each and may possibly have been overlooked at the exceptions mentioned.

  Agave lechuguilla, Euphorbia antisyphilitica, Larrea tridentata and a Mimosa species were present at all four West Texas sites. Karwinskia humboldtiana was present at all South Texas sites that included Lophophora as well as on all three additional properties we visited in South Texas that lacked Lophophora. 

  All of the plants mentioned also grow many places lacking any Lophophora.
