Garzon Venegas, J., Gonzalez, F. & Velez Puerta, J.M. Burmeistera minutiflora (Campanulaceae-Lobelioideae), a new species from the high Andes of Antioquia (Colombia) with the smallest flowers in the genus. Anales Jard. Bot. Madrid 69(2): 243-246. Burmeistera minutiflora (Campanulaceae-Lobelioideae), a new species of sect. Barbatae, is here described, illustrated, and keyed out with respect to other species of the genus with small flowers (i.e. corolla tube <1 cm long). The new species is a small herb that grows in the understory of remnants of cloud montane forests of the Western cordillera of Antioquia, Colombia. The dimensions of the corolla and the berries correspond without doubts to the smallest size of reproductive structures in the genus. The small floral size contrasts with the colorful, bright red and yellow corollas.
