Answer: No. its not possible to stick the specimen without pressing it .
Explanation:
the specimen should be pressed well with heavy books, or objects.. this is because, it helps to take out the water/ fluid inside the specimen.. and so it dries up. If it i not dried up properly.... the specimen cannot b stored. Many microorganisms may develop... and destroy ur specimen and the herbarium sheets...both.
