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
Portia labiata from Queensland showed the same patterns of responses between the sexes. Among "P. labiata" and some other "Portia"s, when adults of the same species but opposite sexes recognise each other, they display at 10 to 30 centimetres. Males usually wait for 2 to 15 minutes before starting a display, but sometimes a female starts a display first. A female "P. labiata" that sees a male may approach slowly or wait. The male then walks with erect and displaying by waving his legs and palps. If the female does not run away, she gives a propulsive display first. If the male
