Isachne australis, Br.
This species is plentiful in swampy places and by river-sides, from the North Cape to Upper Waikato, occurring sparingly from that district to Lake Taupo.
It is a slender species, affording a heavy yield of excellent herbage, which is greedily eaten alike by horses, cattle, and sheep. Its value was fully realized during the early settlement of the Waikato, where in many situations it was almost the only species available during the summer months.
For cool moist lands, especially those liable to occasional inundation, it must be considered a grass of the highest value, and should be generally cultivated in these situations. On the margins of rivers it assumes a sub-fluitant habit, and in some parts of the Waikato may be pulled from the water-margin in immense quantities. It is not adapted for cultivation in the South Island.
