Grasses or Poaceae

Two common grasses in a local meadow: Yorkshire Fog (Holcus lanatus) and Sweet vernal grass (Anthoxanthum odoratum)

The family of Poaceae (number 177, or  the last family in Stace’s  and most other modern Floras) has 5 Sub-families and 16 tribes.

It is by far the largest family in the temperate world as grasses flourish in nearly every habitat!

Stace does mention many obvious non-natives which have naturalized in several places, as well as crop plants which have been grown in the B.I. for many centuries.

Many people find grasses hard to identify and this is mostly due because of their small parts, which often need  be looked at through magnifying glasses and of course they are mainly all green!

However with a bit of practise and knowledge into which diagnostics to look for, they are not too difficult. It can get adictive as the flowers are often beautiful!

I use colour coding for easy reading! Blue background is general interesting info (although I hope you find it all interesting!!). Green is about all the uses except for medicinal uses or if there is a warning in which case I use a pink background. Amber coloured background is for all the cereal grasses this time.

Here a gallery of pictures by Mike Poulton of various grasses from different habitats.
