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 spiders, none of which are as dangerous to "P. labiata". The Los Baños variant has a slightly wider repertoire of tactics. In the Philippines, "P. labiata" does not prey on ants, but is preyed on by the ants "Oecophylla smaragdina" and "Odontomachus" sp. (species uncertain), and a solitary "Odontomachus" has been seen attacking a "P. labiata". In a test the ant "Diacamma vagans" usually killed single-handed a "P. labiata". "P. labiata" is one of 17 species in the genus "Portia" as of May 2011. This species has been named "Sinis fimbriatus" (Hasselt, 1882; misidentification), "Linus labiatus" (Thorell, 1887), "Linus dentipalpis"
