Charles Ledger

Ledger did a great service to the world, as millions of cinchona trees grown in India and Java sprang originally from the seeds he collected.

•

Ledger, however, found a better variety for producing quinine, now known as Cinchona ledgeriana, and in 1865 under great difficulties collected several pounds of seed and sent them to his brother George Ledger in London.

•

In 1883 Ledger went to Sydney again and in 1884 took a farm 20 miles (30 km) from Goulburn, New South Wales.

•

Some seeds and plants had been introduced into Europe and Asia by Hugh Algernon Weddell in 1848, and Sir Clements Markham went later to Peru, and Bolivia, and succeeded in acclimatizing trees in Asia and the Dutch East Indies.
