Serrated Tussock – Be on the Lookout

 

Serrated Tussock

ONE OF OUR WORST WEEDS.

We have it in the Tamar Valley, we just need to get rid of it!

Contact Tamar NRM 6323 3310 if you want further identification tips emailed or posted. But if you think you have it don’t transport it to get an ID. It’s better to ring DPIPWE 1300 368 550 or Tamar NRM 6323 3310 to have it identified in situ.

 Here is a great video clip

IDENTIFICATION TIPS:

  1. Leaf bases of serrated tussock are more tightly packed and more slender than those of other tussocks and are never purple or blue-green, but a whitish colour.
  2. In summer when most other grasses have dried off to a straw-colour, the young serrated tussock plants still retain their bright green colour, except for the tips which are bleached.
  3. At the junction of leaf sheath and blade most grasses carry a small flap known as a ‘ligule’. In the case of serrated tussock this is white, papery, rounded at the tip and never hairy.
  4. The upward-pointing barbs on the leaf blade, which gives them their rough or serrated texture, are minute and almost invisible to the naked eye. If the leaves appear at all hairy, the plant is not serrated tussock.
  5. The seed head breaks off whole. The previous year’s seed heads do not generally remain on the plant.
  6. Flowering and seeding heads are a dark purple due to the colour of the two ‘glumes’ surrounding the seed.
  7. Seed of serrated tussock is unlike the seed of any of the other tussock grasses with which it is likely to be confused.
  8. For help in identifying serrated tussock, search the Dennis Morris Weeds and Endemic Flora Database for serrated tussock illustrations.
