Barry Ruderman form Raremaps.com posted this map in the wild on one of the glass houses at Kew Gardens during the Orchid Festival last year. The Wallace Line is a boundary line drawn by Alfred Wallace an English biologist in 1859 that separates the biogeographical regions of Australia and Southeast Asia and where he observed stark contrasts in the species of fauna on each side of the line. If you are interested the Orchid Festival at Kew takes place in February.
