Description

Leaves

Festuca nigrescens is perennial, caespitose, and densely clumped. Butt sheaths are persistent, investing on the base of the culm, along with fibrous dead sheaths. The culms grow from 30 - 90 centimeters long. The leaf sheaths are tubular, with flat margins glabrous on their surface. Ligules are an eciliate membrane. The leaf blades are filiform, conduplicate, and are 0.4 to 0.7 millimeters wide. Leaf blades are either dark green or glaucous. The venation of the leaf blades have 5 - 7 vascular bundles, along with strands of sclerenchyma below the veins (some are above the veins). The leaves are smooth, or scabrous, and rough adaxially.[1]

Inflorescence

The inflorescence is in open panicles, which are 4-10 centimeters long. The panicle branches are scabrous. The spikelets are solitary, whereas the fertile spikelets are pedicelled.[1]
