BOTANICAL NAME: Costus juruanus
FORMAL SCIENTIFIC NAME: Costus juruanus K.Schum.
STATUS :Accepted
CONTINENT: Neotropical

P. J. M. Maas in Flora Neotropica.- Listed as "insufficiently known species", confused with Costus productus. "it is very difficult to interpret Schumann's C. juruanus, as the original material was destroyed in 1943. The "type-photograph" (from Jurua-Mirim instead of the "mittleren Jurua" as indicated in Schumann's original description) gives good details of the ligule and leaves, but the infl. is completely invisible, hidden by one of the uppermost leaves. As I have already confused this type-material with the present C. productus, I hesitate to interpret it a second time. I therefore prefer to put this name in the list of insufficiently known species.

Schumann describes this species and places in subgenus Eucostus - Das Pflanzenreich IV, 1904.
