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 is about equally effective with all sizes of web spiders up to twice "P. labiata"′s size. A female "P. labiata" is effective against insects up to twice "P. labiata"′s size when the insect is stuck in a non-salticid's web, and against insects not in webs and up to "P. labiata"′s size, while "P. labiata" seldom pursues or catches a larger insect in the open. A female "P. labiata" very seldom pursues or catches a larger insect in her own web, and is slightly less effective against smaller insects in "P. labiata"′s web than in other situations. Males are less efficient
