Type. Frequent in scrub savanna, Araracuara, Rio Caqueta, 5 Sep 1959, Amazonas, Colombia, B. Maguire. C. K. Maguire & A. Fernandez 44129 (holotype NY, isotype US). Paratype. Araracuara Savannas, 6 Sep 1959, 44173.
Specimens of subsp. wurdackii are readily distinguished from the Caqueta variant by their coarser, longer, fewer leaves, fewer scapes (1 or 2, in subsp. eaquetensis commonly 3-5), and persistently densely tomentose, narrower bracts, which in the Colombian variant are broader and become at length somewhat glabrescent.
