BOTANICAL NAME: Costus guanaiensis
SUBGENUS:Costus
GROUP:1-bracts with appendage

SECONDARY SOURCES:Manual de Plantas de Costa Rica Vol II, 2003, Missouri Botanical Garden
LAST UPDATED:
NOTES AND DISTINGUISHING CHARACTERISTICS:In Flora Neotropica No. 8, Maas classifies 4 varieties keyed as follows:
var. guanaiensis (s Colombia, e Peru, w Bolivia and Costa Rica - Sheaths hirsute to strigose and lower side of leaves ferrugineous-villose, upper side strigose to glabrous
var. asplundii, later reclassified by Maas as a separate species, C. asplundii (Ecuador) - Sheaths hirsute to strigose and lower side of leaves strigose, upper side glabrescent
var. macrostrobilus - Sheaths puberulous, villose or glabrous and upper side of leaves strigose, somewhat scabrid to touch
var. tarmicus - Sheaths puberulous, villose or glabrous and upper side of leaves glabrous to puberulous
NOTE: this is also closely associated (by key) with an unnamed C. aff. claviger species that Maas described.
NOTE 2: In Flora Neotropica No. 18, Maas mentions a Costa Rican specimen that matches Costus bracteatus which is syn. of C. guanaiensis var. guanaiensis, except for having strongly plicate leaves.
NATURAL DISTRIBUTION:Rain forests, riverbank forests or swamps in Central America, n and w South America, sea level to 1600 meters.
