Carex rugulosa, also known as the thick-nerve sedge or the slender-culm thick-nerve sedge,[1] is a tussock-forming perennial in the family Cyperaceae. It is native to the eastern parts of Asia.[2]
The rhizomous sedge has a prostrate stem, known as a stolon that runs along or slightly below the surface of the ground. It is able to produce new plants from buds found at the tip or nodes. The stems, or culms, of the sedge are typically 50 to 80 cm (20 to 31 in) in length with a triangular cross-section. The culms are smooth toward the bottom and become rougher toward the top. The base is often surrounded by red-brown coloured sheaths that deteriorate into a fibrous mass over time.[3] The leaves are almost as long as the culms and have flat, stiff and sheathed leaf-blades that are 3 to 5 mm (0.12 to 0.20 in) wide. There are clusters of leafy bracts beneath in inflorescences. The inflorescences consist of four to six spikes that have a narrowly lanceolate shape and are 1 to 3.5 cm (0.39 to 1.38 in) in length.[3]
Taxonomy
The species was first described by the botanist Georg Kükenthal in 1903. It has one synonym, Carex smirnovii[2]
