Zoysia matrella (L.) Merr., commonly known as Manila Grass, is a species of mat-forming, perennial grass native to temperate coastal southeastern Asia and northern Australasia, from southern Japan (Ryukyu Islands), Taiwan, and southern China (Guangdong, Hainan) south through Thailand, Indonesia, Malaysia and the Philippines to northern Australia (northeast Queensland), and west to the Cocos Islands in the eastern Indian Ocean.
Other common names include Korean grass, Manila templegrass, siglap grass (after an area in Singapore), temple grass, Mascarene grass, harishiba, hierba Manila (Spanish), Japanese carpet, jukut kakawatan hijau (Sundanese), rebha sekem-sekeman (Madurese), burikit (on Seram), rumput siglap (Malay), damong-alat, barit-baritan (Tagalog), malakuwerdas (Pangasinan), ya-nuannoi (Thai).
Botanical synonyms include Agrostis matrella (basionym), Osterdamia matrella, Z. pungens, and Z. tenuifolia (now distinguished as Zoysia matrella var. pacifica).
Two varieties are distinguished by some authors:
It forms extensive, velvety, green mats, spreading vigorously by stolons, or occasionally by rhizomes, once established. Z. matrella grows in low elevation preferring sandy soils where other grasses establish poorly. The stems are slender and prostrate, ranging from 5-25 cm in length. The leaves are alternate, produced at 1.5-3 cm intervals along the stem; they are slender, 2-10 cm long and 1-3 mm broad. The flowers are greenish, produced on erect racemes 6-35 mm long with a single 2-3.5 mm flower in each spikelet.
The variety of common names attests to its widespread occurrence in these regions along with its usefulness as a cultivated grass in diverse areas. It is naturalised in many places, as in Hawaii, and can become weedy, like many plant species with desirable horticultural characteristics.
