Growing now in only high and inaccessible areas, such as the Ramtops, Counting pines are one of the few known examples of 'borrowed evolution'. A counting pine seed coming to rest anywhere on the Disc picks up the most effective genetic code, and grows into whatever best suits the climate, usually usurping the local plants.
The other notable feature of this remarkable plant is that it produces, at eye-height, numbers detailing its precise age. Its chain of reasoning is as follows; being dimly aware that humans can tell a tree's age by counting its rings, it has reasoned this must be why humans cut trees down.
Unfortunately, within a year they were driven almost to extinction by the house number-plate industry.
This plant has appeared in Reaper Man.
