Cattleya warscewiczii 40; the haploid chromosome number as "n" = 20. "C. warscewiczii" hybridizes naturally with "C. aurea / dowiana", producing "C. x hardyana". "C. warscewiczii" has also been used extensively in Cattleya hybridization, to produce large-flowered hybrid Cattleyas. Cattleya warscewiczii Cattleya warscewiczii (The "Warscewicz's Cattley's orchid"), a labiate "Cattleya", is a species of orchid. It was first collected by Józef Warszewicz in Colombia in 1848-49 and formally described by Heinrich Gustav Reichenbach in 1855. "C. warscewiczii" exhibits a typical Cattleya sympodial habit. Pseudobulbs are 8-16" (20-40 cm) long, unifoliate, cylindrical or cigar-shaped, grooved. Flowers are 7-11" (17.5-27.5 cm) across, largest in
Invasive species in Mexico and the Aquatic. Less affected ecosystems are Sarco Scrub, Misty, and Savannah, followed by Low Evergreen Forest (UNIBIO, s.a.). Today the threat has increased and incidences of invasive plants in Mexico is caused by two factors. Firstly, the increase of invasive plants is attributed to a parallel increase in disturbed areas in the country, caused by logging and a growing number of abandoned pastures. The second is the introduction of exotic species to the territory by human activity, either voluntarily or involuntarily. Of the exotic species in Mexico, only a small percentage becomes invasive, which occurs when the plant is
