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 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]
The species was first described by the botanist Georg Kükenthal in 1903. It has one synonym, Carex smirnovii [2]
The range of the plant extends from Tuva in Russia in the north west down to the northern part of Central China in the south west, through the Korean Peninsula to Japan in the east. [2] It can grow in along the lower reaches of rivers and in brackish marshes forming dense stands. [4]
Carex hirta, the hairy sedge or hammer sedge, is a species of sedge native across Europe. It has characteristic hairy leaves and inflorescences, and is the type species of the genus Carex.
Carex pilulifera, the pill sedge, is a European species of sedge found in acid heaths, woods and grassland from Macaronesia to Scandinavia. It grows up to 30 cm (12 in) tall, with 2–4 female spikes and 1 male spike in an inflorescence. These stalks bend as the seeds ripen, and the seeds are collected and dispersed by ants of the species Myrmica ruginodis.
Carex eburnea, known as ivory sedge, ebony sedge, and bristleleaf or bristle-leaved sedge, is a small and slender sedge native to North America, from Alaska and Newfoundland south to central Mexico.
