Brachypodium sylvaticum - Wood False-brome

Wood False-brome
Have you seen Brachypodium sylvaticum  in flower this late in the year?

We found Brachypodium sylvaticum - or to use its English name - Wood False Brome  - still in flower  - well fruit rather -  on our Fungus Foray earlier this October at Clapham Woods -

The Woods are on limestone so the soil is basic -you can see Dog's Mercury in the photo too - another plant which likes basic soil.

How can you recognise Brachypodium sylvaticum?

There are lots of features making Wood False-brome easily recognisable

  • It usually grows in woods (or in base-rich grassland close to woods)
  • The shoots grow in tufts
  • The shoots are very slender at the base
  • The blades are
    narrow at the base,
    very wide in the middle
    and then taper
  • The blades droop

  • The blades and sheaths are to some extent hairy
  • There are NO AURICLES (as in the similar Hairy Brome, which grows with it in  woodland habitats)
  • The tufts can look yellowish in spring

  • The inflorescence is a drooping spike or raceme - the spikelet stalks are about 1 mm long.
