The cones of limber pine are typical of a 5-needle pine in that they are longer than broad. However, the limber pine cone is chunky. The tips (apophyses) of the scales are thick and have heavy drops of white resin. It is easy to identify this species by cone.
NOTE: The thickened exposed part of each cone scale is called the apophysis. The umbo is the terminal protuberance on the tip of the apophysis. The umbo may be prickled or just slightly raised or pointed.
