The first specimens of V. rosulatula were collected by the conservationist and alpinist André Ilha in 2009, who found it near the top of the rock “O Gordo”, in Córrego do Ouro, county of Guaratinga, Bahia, near the border with Minas Gerais. The specimens introduced in cultivation never flowered. Only recently, flowering specimens were found, this time in the not distant county of Jacinto, Minas Gerais. As in the previous collection, V. rosulatula was observed growing exclusively on unaccessible nearly vertical rock wall in the north region of Minas Gerais state, close to the border with the state of Bahia, where breath-taking inselberg formation prevails in the scenery, in domain of the Atlantic Forest biome, although most of the primitive forest of the region has been devastated in the past decades, with only few small forest fragments left. This new species lives under full sunexposed sites or sometimes in more or less shaded watersheds. Despite V. rosulatula is not truly caulescent, it presents a somewhat elongated stem due to continuous vegetative propagation in those shaded places. —SeeLeme 2012a
