I want to know the answer to the following question:
In what year to Candolle introduce the Candollean system?
All the background I'm provided with is that "The Candollean system reflected his ideas of the progression of morphological complexity and the later classification by Bentham and Hooker, which was influential until the mid-19th century, was influenced by Candolle's approach.". Is that enough to answer the question?
Answer: no
