Origin and HistoryPermalink

P. moctezumae was discovered in 1994 during the investigations on the ecological impact of the future building of the Zimapan dam on the Moctezuma canyon. For memory, this is also during the same investigations that was discovered Pinguicula elisabethiae and published later in 1999.

Location / MapPermalink

• Pinguicula moctezumae can be found in the canyon of the Rio Moctezuma, state of Hidalgo and in Queretaro state (Rio Moctezumae is the frontier between Queretaro state and Hidalgo State), not far the city of San Joaquin, Municipality of Cadereyta.

HabitatPermalink

According to the Author, Pinguicula moctezumae grows on calcium carbonate concretions, in the stream bed or walls with water drainings, on wet limestone slope (I think it is Tufa) at altitudes of 900 to 1100m.

tufa : calcium carbonate A chemical sedimentary rock composed of calcium carbonate, formed by evaporation as a surficial, spongy, porous, semifriable incrustation around the mouth of a hot or cold spring or seep, or along a stream carrying calcium carbonate in solution, and exceptionally as a thick, bulbous, concretionary or compact deposit in a lake or along its shore. It may also be precipitated by algae or bacteria.	Pinguicula moctezumae Photo : Vic Brown - April 2003 -
Wonderfull view on the National Parc of "Los Marmoles" near Zimapan in Hidalgo State. Los Mármoles (National Park) San Vicente gorge, almost 610 meters deep, and Cangando Mountain at 3,018 meters are the principal attractions of this 57,875 acre park. Forests of pine, juniper and wild walnut cover the gorge and mountains, and various animals and birds inhabit the area.
