tlie points generally turned down\yards. But even on the same 

 tree the leaves vary, and those on robust leader-slioots and 

 on the fertile branches often diifer from those on the lateral or 

 younger shoots. Four-sided leaves are not uncommon on the 

 fertile branches. la the dimensions of the cone and the extent 

 to which the bracts project there are equally great variations. 



The cones are, when young, frequently of a purple colour, 

 fading into olive-brown. Sir John AValrond informs me that 

 the cones formerly produced on his trees in cultivation were 

 purple, but that of late years, although " the cones maintaiq 

 their size, they are of a full brown colour, though produced on 

 the same tree."

 flexion of the points of the bracts (see woodcut, fig, 18).
