The mouse has given us numerous names, such as mouse-ear (_Hieracium pilosella_), mouse-grass (_Aira caryophyllea_), mouse-ear scorpion-grass (_Myosotis palustris_), mouse-tail (_Myosurus minimus_), and mouse-pea.
The term rat-tail has been applied to several plants having a tail-like inflorescence, such as the _Plantago lanceolata_ (ribwort plantain).
The term toad as a prefix, like that of dog, frequently means spurious, as in the toad-flax, a plant which, before it comes into flower, bears a tolerably close resemblance to a plant of the true flax.

The frog, again, supplies names, such as frog's-lettuce, frog's-foot, frog-grass, and frog-cheese; while hedgehog gives us such names as hedgehog-parsley and hedgehog-grass.
Connected with the dragon we have the name dragon applied to the snake-weed (_Polygonum bistorta_), and dragon's-blood is one of the popular names of the Herb-Robert.

The water-dragon is a nickname of the _Caltha palustris_, and dragon's-mouth of the _Digitalis purpurea_.
Once more, there is scorpion-grass and scorpion-wort, both of which refer to various species of Myosotis; snakes and vipers also adding to the list.

Thus there is viper's-bugloss, and snake-weed.

In Gloucestershire the fruit of the _Arum maculatum_ is snake's-victuals, and snake's-head is a common name for thefritillary.
