Roraima : Caracaraí , Viruá National Park , elevation 67 m , 1º29’11’’N , 61º02’41’’W , 26 November 2009 , fr., Cabral et al. 20 ( INPA ) ; Ibid. , elevation 60 m , 1º27’01’’N , 61º00’48’’W , 2 December 2009 , fr., Cabral et al. 91 ( INPA ) . Taxonomic notes :—It is possible to differentiate Tovomita spruceana from T. umbellata Bentham (1843: 367) only by vegetative characters. Tovomita spruceana has shorter internodes and leaf lamina and a longer petiole than T. umbellata . When in floral buds, Tovomita spruceana is distinguished by T. umbellata by its oblong floral buds with rounded apex (vs. ovate floral buds with acute apex in T. umbellata ).
