Hallo, Dieter,
ich lehne mich hier an den Werken von Halbinger & Soto: "Orchidea Mexico, Laelia of Mexico" - wohl führend zu dem Thema
Das Verbreitungsareal von L. speciosa ist recht breit im Norden Mexicos: " DISTRIBUTION: Endemic in the Sierra Madre Occidental, Oriental, the Transverse Volcanic Belt, and the southem part of the Mexican Plateau. LaeLia speciosa can be found in a very large area in Mexico, in the states of Durango, Zacatecas, Aguascalientes, Jalisco, Guanajuato, Michoacán, Querétaro, Hidalgo, San Luis Potosí, and Tamaulipas"
Zum Klima Seite 32, letzter Absatz - ab Ende Mai/Juni bis Oktober ".... humid winds mean daily, heavy rainfall.......".
weiter Seite 140 " HABITAT: The plants grow on oaks (almost always on Q. deserticoLa and Q. Laeta) in open, deciduous, stunted forests at an altitude of 1900 to 2500 meters. They withstand severe drought from December to June and tolerate short periods below O°C temperatures. Annual rainfall is from 700 to 1000 mm..."
Grüße
Laetitia
