In Poul Anderson's Psychotechnic History:
I have yet to read "Green Thumb" but an internet book review reveals that it is about human beings who colonize a planet, then suspect that one of its species is intelligent;
"Virgin Planet" reveals that the Stellar Union Coordination Service has a base on the planet Nerthus and that Carsten was a planetary explorer or discoverer;
The Peregrine reveals that Nerthus is Carsten's Star III;
"The Pirate" reveals that Nerthus was humanly colonized before it was realized that it already had intelligent life.
These clues generate a high probability that "Green Thumb" is about Carsten on Nerthus. I still know nothing about the other uncollected story, "The Acolytes."
