Grasses and Horsetails

Grasses can be very tricky to identify, but I'm working on them. This is Meadow Foxtail - Alopecurus pratensis.


And this is Sweet Vernal Grass - Anthoxanthum odoratus. More to follow.


There is a small patch of the hedgerow where I have four different Horsetails within about 15m of each other. I already showed the Equisetum arvense. This is Marsh Horsetail - Equisetum palustre:


Note: small number of smooth ridges round the stem and white-edged teeth.


This is Water Horsetail - Equisetum pluviatile:


Note: more numerous ridges with black teeth.


The fourth version is the hybrid between Field Horsetail and Water Horsetail - Equisetum x. litorale. If I can get some illustrative shots of this I'll put them up.
