Description
editTibouchina nigricans is a short, unbranched shrub with a dark purple hypanthium and calyx lobes. T. nigricans is similar to T. aegopogon and T. johnwurdackiana as these species each have only a single stem, although there are distinguishing differences in the trichomes and indumentum of the leaves and hypanthium.[4]
Distribution and habitat
editThis species is found in the states of Goiás and Distrito Federal in Brazil. It prefers open grassland including the campo sujo and cerrado rupestre. It has been found at elevations between 1,100 and 1,200 metres (3,600 and 3,900 ft). T. nigricans is only known from four collections. It has recently been found in Parque Nacional de Brasília and Serra dos Pireneus.[4]
