Malme (I.c.) wrote of A. pervaginata, "A. grandis Griseb., cui quoad folia similis, peraffinis. Differt praecipue scapo multo altiore et paribus quatuor vaginarum instructo." The collection from Cerro Parti, Cowan & Wurdack 31146, cited above, has scapes provided with 3-5 pairs of bracts, and exceeds in height those of Ducke 18967.
