Carex dickinsii |
Carex dickinsii, also known as Dickins' sedge [1] or chao xian tai cao in pinyin, [2] is a tussock-forming species of perennial sedge in the family Cyperaceae. It is native to parts of Japan, Taiwan and south-eastern China. [3]
The sedge has a rhizome and forms slender stems that arise from underground. It forms 20 to 70 cm (7.9 to 27.6 in) long culms that have a triangular cross-section and have a rough texture on top and are smooth underneath. The culms have yellow to brown coloured sheaths at there base. The stiff and flat leaves have a width of 4 to 8 mm (0.16 to 0.31 in) and are the same length or longer than the culms. The leaves have sheathed and transverse nodes that are compartmentalied between the veins. It has leaflike bracts that appear in a whorl underneath the inflorescences. The flower spikes usually occur in groups of three with a lateral female spike and a club shapeed terminal male spike that is 1.5 to 2 cm (0.59 to 0.79 in) in length. [4]
The species was first described by the botanists Adrien René Franchet and Ludovic Savatier in 1878 as a part of the work Enumeratio Plantarum in Japonia Sponte Crescentium [2]
It has one synonym; Carex coreana described by Liberty Hyde Bailey in 1889. [3]
The sedge is found in temperate areas of eastern Asia, from Japan in the north, Korea and the Fujian province of Chine in the south. [3]
