Lehnert, Marcus, 2011, Species of Cyathea in America related to the western Pacific species C. decurrens, Phytotaxa 26, pp. 39-59 : 55-56

38. Cyathea vaupensis (Windisch) Lehnert , comb. et stat. nov. Basionym: Sphaeropteris macrosora (Baker) Windisch var. vaupensis Windisch (1973: 374) . Type:— COLOMBIA. Vaupés: Cerro Isibukuri, Río Kanari, Comisaria del Vaupés, Schultes & Cabrera 13407 (holotype GH).

Distribution and habitat: — Colombia, Venezuela, Guyana, Suriname, French Guiana, Ecuador, Peru, Brazil, in moist forests on terra firme between 75– 500 m.

Remarks: —Easily recognized and distinguished from Cyathea macrosora by its ample cover of persistent, clearly bicolorous petiole scales, which reach along at least the lower half of the rachises. Cyathea

vaupensis is recognized here at the species level, because its differences with C. macrosora are even more evident than those of C. macrosora var. reginae , which has already been accepted at the species level as C. traillii .
