Anthosachne sacandros is a species of true grass in the tribe Triticeae. It is endemic to open habitats in the Marlborough Region of New Zealand.[3] It grows on limestone cliffs, bluffs and river terraces, from elevations of 0–900m. It flowers from October–February, and fruits from December–May.
It is a medium-size, tufted, perennial grass. It is a long-awned Anthosachne, with spikelets appressed to the rachis, and with involute leaf-blades. It is most similar toA. falcis, from which it can be distinguished by its erect growth form, and long, thin, ribbed and glaucous leaf blades, with a dense weft of hairs at the leaf blade–ligule junction.[4]
Threats
Anthosachne sacandros is listed as At Risk - Naturally Uncommon by the New Zealand Threat Classification System. Its threats are poorly known, and there is little information about population size or trends.[5]
Flora in the Marlborough Region is threatened by introduced species such as the common brushtail possum, and plants such as Lycium ferocissimum and Pinus contorta. Fire, floods and erosion are common in the Marlborough Region, and can potentially impact range restricted species like A. sacandros.[6]
