Richard Schultes: I had made a tremendous collection of plants, and the airplane that was going to take me out [of the jungle was the same one that] took me in. After a while in the early days, I had to go in over land and over by canoe and so forth. Later, I could fly in with hydroplanes. I would make an agreement with the pilot that on such-and-such a day — let’s say two months, three months later, weather permitting — he’d be there. I’d have to put out a bed sheet, so he could see I was there before he landed. But when the day came, there was no plane. It was a beautiful day, and he had always come on the day expected, but I said, “Maybe he’s had some more urgent thing to do.” So I waited and waited. I couldn’t go more than a quarter of a mile away from that house in the forest because with the canopy of the top trees you can’t hear the planes early enough to run back and put out that sheet. So I often say that that half-mile area — a quarter mile each way around that house — is the most thoroughly studied botanical area in the world. There isn’t a moss that escaped my eye!
