Discussion
The two disparate populations, subsp. wurdackii on Neblina and subsp. chimantensis on Chimanta-tepui, are at once recognized to represent a common species, characterized by essentially identical habit and floral morphology. The Neblina population has become a plant of less robust habit, relatively few peduncles, and slightly larger spicules and flowers. The Chimanta population is more robust, productive of relatively larger numbers and somewhat coarser peduncles, and perceptibly smaller flowers. The closest relative of S. wurdackii is; S. pauciflora Gleason of Cerro Duida.
