Today I want to tell about Flora in USA Great Britain and Kazahstan.At first sight(с первого взгляда) , I thought that there are practically no Flora.But I was mistaken.There are a lot of Flora there.I will name some.
In Usa there are a lot  of berrys, some dwarf willows and there are birchs.
And some cereals
In Great Britain there are a lot of forests and beautiful flowers.For example wild daffodil, lilies, purple orchids and primroses. 
In Kazahstan there are a lot of forests too.But Flora is not very big because half a countrie is sand.Also there are some flowers.
Thank you for you attention!
