Bentham's Method. Eucalyptus caesia 'Silver Princess', Western Australian Botanical Garden, Kings Park, Perth, Australia
Sad father James Drummond - see earlier posting - was the first collector (1847) of this beautiful Eucalyptus from the Wheatland area around what is today Perth. It was named Eucalyptus caesia (gray- or silver-barked eucalypt) by George Bentham (1800-1884) in 1867 when he - in England, and basing himself partly on the Drummonds's work - was making an important inventory of the flowers of Australia between 1863 and 1878.
George was a favorite nephew of the famous utiliitarian philosopher Jeremy Bentham (1748-1832). Jeremy made George his heir which gave the latter the means to live and work independently.
It is said that George's botanical work was influenced by the fact that he adopted his uncle's philosophical/scientific method. He was no doubt influenced by the man because he was Jeremy's secretary from 1826 onwards. But I'm not (yet) sure how that influence exactly reflects on George's botanical work.
The sky was bright when I took this photo and it blacked out my first attempts. Then I used a flash...
