Cynodon dactylon (L.) Pers.
Indian doab (Cynodon dactylon) is a long-lived, perennial grass that is native to Africa, Europe and Asia. It was introduced to New Zealand as a pasture grass and was first recorded in the wild (naturalised) in 1846. The plant forms dense mats from creeping stolons and rhizomes and has narrow grey-green leaves. It flowers from December to April, producing slender seed heads with three to seven finger-like spikes radiating from the top of the stem, which develop into small seeds. It tolerates drought, heat, grazing and a wide range of soil types. It reproduces by seed and vegetatively from stolons and rhizomes. Seeds are dispersed by water, animals and human activities. Stolons and rhizomes are spread by soil movement, cultivation and other human activities, and fragments readily produce new plants.
