In the death of this gentleman who, on September 10th passed away in his eighty-fourth year, we lose one of the greatest botanists of our age. His name is connected with so many plants, that in this way alone he will be familiar to most of our readers outside of immediate botanical circles. He was connected with Dr. Hooker, some years ago, to prepare a work describing all the Genera known, and this he fortunately lived to see completed. Thus, the "Genera Plan-turum," by Bentham and Hooker, will truly remain a monument of learning and patient industry.
