“If a tree dies, plant another in its place.”

I demand of you, and of the whole world, that you show me a generic character by which to distinguish between Man and Ape. I myself most assuredly know of none.

We admit as many genera as there are different groups of natural species of which the fructification has the same structure.

Fragments of the natural method must be sought with the greatest care. This is the first and last desideratum among botanists. Nature makes no jumps. All taxa show relationships on all sides like the countries on a map of the world.

Linnea- A plant of Lapland, lowly, insignificant, disregarded, flowering but for a brief space – from Linnaeus who resembles it.

In natural science the principles of truth ought to be confirmed by observation.

A herbarium is better than any illustration; every botanist should make one.

A professor can never better distinguish himself in his work than by encouraging a clever pupil, for the true discovers are among them, as comets amongst the stars.

If you do not know the names of things, the knowledge of them is lost, too.

Natural bodies are divided into three kingdomes of nature: viz. the mineral, vegetable, and animal kingdoms. Minerals grow, Plants grow and live, Animals grow, live, and have feeling.

It is not God, but people themselves who shorten their lives by not keeping physically fit.

A practical botanist will distinguish at the first glance the plant of the different quarters of the globe and yet will be at a loss to tell by what marks he detects them.

The species and the genus are always the work of nature [i.e. specially created]; the variety mostly that of circumstance; the class and the order are the work of nature and art.

The plant kingdom covers the entire earth, offering our senses great pleasure and the delights of summer.

Blessed be the Lord for the beauty of summer and spring, for the air, the water, the verdure, and the song of birds.

No one has been a greater botanist or zoologist. No one has written more books, more correctly, more methodically, from personal experience. No one has more completely changed a whole science and started a new epoch.

It is the genus that gives the characters, and not the characters that make the genus.

Excess of grief for the dead is madness; for it is an injury to the living, and the dead know it not.

The life of the dead is placed on the memories of the living. The love you gave in life keeps people alive beyond their time. Anyone who was given love will always live on in another’s heart.

For the whole life of a philosopher is, as the same philosopher says, a meditation on death.

We’re all going to die, but does that mean we have to be buried alive?

There is no class that cannot be wiped out if a sufficient number of its members are murdered.

Territory matters, and there is little difference between territorial rights and social status. It is often a matter of life and death.

We have been dying since we got here and forgot to enjoy the view – live fully.

Life is a disease: sexually transmitted, and invariably fatal.
