The Pine which is here figured was discovered by 
J. Jeffrey in the Shasta Valley in North California when 
collecting for an Edinburgh association in 1852. Seeds 
were sent by him to Edinburgh in the same year, and in a 
circular to the subscribers issued by Andrew Murray it is 
explained that these were distributed by the committee 
under the names given to them by various botanists, the 
figures and descriptions of the cones, leaves and seeds of the - 
Jung, 1909.
