A common critique levelled at Culpeper's Herbal was how many plants he neglected to describe... which was sometimes part of the fun!
Chestnut: It were as needless to describe a tree so commonly known as to tell a man he had gotten a mouth.
Crowfoot: Abundance are the sorts of this herb, that to describe them all would tire the patience of Socrates himself, but because I have not yet attained to the spirit of Socrates, I shall but describe the most usual.
Dragons are so well known to every one that plants them in their gardens, they need no description; if not, let them look down to the lower end of the stalks, and see how like a snake they look.
Elder: I hold it needless to write any description of this, since every boy that plays with a pop-gun will not mistake another tree instead of Elder.
Garlic: The offensiveness of the breath of him that has eaten garlic, will lead you by the nose to the knowledge hereof, and (instead of a description) direct you to the place where it grows in gardens.
Honeysuckle is a plant so common, that every one that has eyes knows it, and he that has none, cannot read a description, if I should write it.
Nettles are so well known, that they need no description; they may be found by feeling, in the darkest night.
Wormwood I shall not describe, for every boy that can eat an egg knows it.
