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

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.

Stones grow, plants grow, and live, animals grow live and feel.

When all the thoughts are concerning one thing and the person loses interest in other things, the melancholy begins.

We get death threats, kidnapping threats. The press criticizes my weight. It’s just the English way.

Many men on the point of an edifying death would be furious if they were suddenly restored to health.

I don’t think any person in America should die because they are too poor to live.

Live as tho death is not the inevitable end.

This is good for you. Death is a thing of beauty, and it needs to be executed in such a way that does it justice.

Death is not the biggest fear we have; our biggest fear is taking the risk to be alive – the risk to be alive and express what we really are.

How exhausting it must be to fear death, when you can simply howl at the moon.

I’ve noticed that about your people, Doctor. You find it easier to understand the death of one than the death of a million. You speak about the objective hardness of the Vulcan heart, yet how little room there seems to be in yours.
