Type.

ECUADOR. [without precise locality], 1859, Jameson s.n. [#59] (holotype: P (P00740364 [image!])).

Comments.

Known only from the type collected in Ecuador, the identity of this taxon remains ambiguous. Calamagrostis spruceana bears similarities to C. macrophylla , C. secunda and C. macrostachya due to its open inflorescence, short hairs of the callus, rachilla hairs not reaching the apex of the palea and awn inserted slightly above the middle of the lemma ( Sodiro 1930: 70; Zulma Rúgolo de Agrasar, pers. comm.).
