Abstract
Janusia guaranitica (A.St.-Hil.) A.Juss. has cleistogamous flowers with only one stamen and two carpels, which are produced before the chasmogamous flowers and often in great numbers. According to Lorenzo (1981), the ovules of both types of flowers in J. guaranitica are identical. Three specimens of J. guaranitica found on public streets in Araras, in the state of São Paulo, Brazil, were transplanted into a Garden on the Universidade Federal de São Carlos, campus Araras, located in an area with remnants of Semidecidual Seasonal Forest. The J. guaranitica specimens produced well-formed fruits from cleistogamous flowers before transplanting. We believe that the general conditions of the garden to which the specimens were transplanted probably did not influenced seed abortion, since they coincide with the conditions reported by Sebastiani (2010) for the occurrence of J. guaranitica, that is occurrence in several phytophysiognomies, including Semideciduous Seasonal Forest and disturbed areas, in rocky, sandy or clayey soils, at altitudes between 150 and 1.700m.
