Neve saw the dirt when the traveler signed the declaration. A dark crescent remained beneath his smallest fingernail, carefully protected while the other nails had been trimmed close.
"Hand, please."
He closed it.
The plant beside him looked perfectly legal. Its roots lay in sterile gel, its leaves were clean, and a laboratory certificate identified it as a harmless food variety. He had paid more for the certificate than most travelers paid for their luggage.
Neve could see that too. She had processed enough declarations to recognize the narrow, exhausted anger of somebody who had complied with every rule and expected compliance to be sufficient.
"The hand."
He held it over the collection tray.
The port admitted plants that could grow in the settlement's controlled systems. It excluded living soil. Three years earlier a harmless terrestrial fungus had established itself in a hydroponic compartment and clogged the nutrient membranes. Nothing poisonous happened. People merely lost three harvests in a place where replacement food took months to arrive.
Neve had helped clear the compartment. She did not need a training film to explain what invisible companions could do.
She took the sample. The traveler watched the little dark crescent leave his nail.
"It will live," he said, nodding at the plant. "It will make leaves. You can keep it for years and think I was lying."
"What won't it do?"
"Flower."
His name was Olan. The plant came from a family of food vines cultivated beneath a different spectrum. Its roots needed a microbial partner to produce the compound that triggered flowering. The sterilization service had removed that partner while making the plant fit to travel. The certificate described germination, leaf development and absence of toxins. It did not promise fruit.
He had kept a little of the old soil under his nail because he had nowhere else to put it that would survive inspection.
Neve returned the plant to the tray. He mistook the movement for confiscation and reached for it. She put her hand in his way, and for a few seconds they stood like that, both embarrassed by the shape of the encounter.
She could destroy the soil and admit the plant. She could reject both. The third option was a controlled cultivation study, something usually reserved for commercial importers with time to wait and rooms at the port hotel.
Olan's ship left in six days.
"It takes longer than that," she said.
He looked at the departure board beyond the inspection glass.
He was going to join a food cooperative on the outer habitat. They had work for him, a berth and space for the vine. He had told them it would bear the fruit he knew how to cook. They could buy protein and sugars anywhere. They had invited him to bring something they did not already have.
Neve called the quarantine supervisor. There was a free growth chamber, but the study required daily care and separate handling of every tool and runoff container. Her department could provide observation time. It could not become a gardener for every confiscated root.
Olan offered to do the work. They gave him a temporary access card that admitted him only to the quarantine corridor, its washroom and the chamber. He slept in a hired bunk near the freight terminal.
In the first few days, the sterile control cutting grew faster than the inoculated one. Olan came out of the chamber carrying his notes as if he expected Neve to use the difference against him. She reminded him that they were waiting for flowers, not a race between leaves.
His departure arrived. The cooperative offered to hold the berth until another ship could take him. He sent his other luggage onward and watched the loading crane swallow it into the vessel he should have boarded.
He was angry with Neve that afternoon. She let him be angry. She had chosen to remain in the port; he had chosen between delays she could name but did not have to bear.
The partner culture proved unable to grow in the settlement's common nutrient medium. That reduced one risk. It did not settle all the others. Neve added the result to the study and kept the chamber closed.
On the twenty-ninth day, Olan called her before her shift. A pale bud had opened between two leaves. The sterile cutting remained vigorous and flowerless beside it.
Neve went down in her coat. They stood on opposite sides of the chamber glass, each able to see the small thing the other had been waiting for.
The eventual permit named both organisms. It required a contained growing bed and periodic runoff checks. Olan read it twice, including the cost. He did not call it fair. He asked the cooperative whether they could manage the bed and what work remained available when he arrived.
The next passage was eleven weeks away. Neve found him in the terminal, calculating bunk charges on the back of the permit. He had placed the plant's photograph beside the figures.
She sat down to help him compare routes. He turned the permit over to make room for the fares.
