Among further animal prefixes may be noticed the wolfs-bane (_Aconitum
napellus_), wolf's-claws (_Lycopodium clavatum_), wolf's-milk
(_Euphorbia helioscopia_), and wolfs-thistle (_Carlina acaulis_). 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. There is the
snake-skin willow and snake's-girdles;--snake's-tongue being a name
given to the bane-wort (_Ranunculus flammula_).
