Cattleya warscewiczii 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 the genus, showy, fragrant. In culture the flowering is in summer on that year`s spring growth. Strong light and good air movement are required. The diploid chromosome number of "C. warscewiczii" has been determined as 2"n" =
Portia labiata the draglines of equal-sized females and then pitted some of them in contests. Other females avoided the draglines of the victors, and spent the majority of their time on draglines of the losers. Similar tests showed that females of "P. fimbriata" from Australia and "P. schultzi" from Kenya do not avoid draglines of a powerful fighter. In "P. labiata" and in some other species, contests between males usually last only 5 to 10 seconds, and only their legs make contact. When hunting, mature females of "P. labiata", "P. africana", "P. fimbriata" and "P. schultzi" emit olfactory signals that reduce the
