Streaked Arrowgrass

Triglochin striata

This grass-like plant grows from a rhizome or underground plant stem capable of producing the shoot and root systems of a new plant. In the photo you can see the series of leaf shoot rising from this stem. The righthand side of the photo shows a part of the flower stem with some of the small flowers and fruits.
It is found in the Salt Marsh Community of plants, so either it was transported to its present site or is surviving from a time when the lake level was some metres higher.
This is possibly why it is very small compared with descriptions of the healthy plants. The flower spike is said to be 1 cm wide, but the spike on this plant is barely half that size.
