Dr M’s series of posts on the Top 20 families of flowering plants kicked off with the three largest families globally: Asteraceae, Orchidaceae and Fabaceae.
However in Britain the size order of the top-twenty families has been documented by UK botanist David Streeter in his recent Wild Flower Guide and these three families are not (quite) the top three in Britain.
Below is David Streeter’s top-twenty plant families which Dr M will cover in this series, listed in order of their speciosity in Britain.
David Streeter’s Top 20 Flowering Plant Families in order of species number in Britain (bold and itallics means family already posted by Dr M, click on the family name for more information):

Lots more gorgeous plants to look forward to in this series!
