This little-known species is based on an over-mature specimen in which the florets have been shed. It appears close to Melica grandiflora, but is excluded from that species by the unequal, acute glumes. The type has not been seen, but is reported to have swollen basal internodes, which are not otherwise found in E Asian Melica species. A second gathering cited in the protologue is a specimen of M. turczaninowiana.
