Leptotes (plant) are mounted on plaques of vegetal fiber or tree cork. Watering and fertilizer must be more frequent during active growth periods and less during dormant periods. Ideal growth conditions require an intermediate temperature and exposure to filtered sunlight. In April 1833, an unknown species from the Serra dos Órgãos mountains of Brazil blossomed in the greenhouse of Mrs. Arnold Harrison, an English collector of orchids homaged in diverse descriptions of noted species such as "Bifrenaria harrisoniae" and "Cattleya harrisoniana". A short time later, Mrs. Harrison sent a drawing and cutting of this plant to the botanist John Lindley, who verified
Portia labiata specimens. The following table shows the hunting performance of adult females. In addition to "P. labiata", the table shows for comparison the hunting performances of "P. africana", "P. schultzi" and three regional variants of "P. fimbriata". A female "P. labiata" often hangs a capture web from pliant stems and leaves of shrubs and lower branches of trees, rather than from rocks and tree trunks. Males of "Portia" do not build capture webs. A female "P. labiata" more often pursues small jumping spiders and web spiders than larger prey. While it more often catches small jumping spiders than larger ones, it
