MATERIAL EXAMINED: Andre 3477 (K, TYPE; US, photo) Colombia near Ipiales, ca. 2900 m, 1876. COLOMBIA.
NOTES: This species although not yet reported for Ecuador is certain to be found there. The type collection site is just north of the Colombia-Ecuador border. The plant is most striking for its very broad spikes, which appear to be nearly as broad as long and which spread out sharply from the rhachis.
