General Description. 
T HE specimen on which the following account is based was 
grown for about thirty years in the Botanic Garden, which 
later became the White City, at Manchester; it was then trans¬ 
planted to the Cambridge Botanic Garden, whence it was sent for 
our examination. Its approximate age was 120 years, and it had 
flowered only once under observation, at Manchester, when a 
female cone was produced. When cut down it was a small tree 
of 65 cms. in height, and 80 cms. in circumference including the 
leaf-bases, with which the trunk was thickly beset. Surrounding 
the apex was a crown of pinnate leaves, each about 135 cms. long. 
At 5 cms. above the ground a lateral bud was found ; this had 
apparently aborted, for periderm thickenings had occurred in places, 
and a deposit of gum was present in spaces in the tissues. The 
trunk was sawn up, and dissections were made of some of the 
pieces. The mucilage and sap which exuded from the cut surfaces
