Sinnott. — The Morphology of the 
P. elatus has a much larger ovule and its thick epimatium is supplied 
by a more complex vascular system. The single basal strand, formed by 
the fusion of two, divides into three which separate considerably as they 
ascend. At the chalazal end these strands enter an anastomosing complex 
of seven main bundles, formed by the three we have just traced, which 
supply the dorsal portion of the epimatium, and by four others which pass 
down its ventral side and end blindly near the micropyle (Diagram i, H). 
These ventral bundles probably represent continuations of the two lateral

members of the dorsal series. They usually fork somewhat and are often 
connected by small strands. The integument is thin and is fused throughout 
its entire length to the stout epimatium, but the inner margin of the latter 
is so fully occupied by distended resin sacs or spaces that the ovule proper 
is virtually suspended from it by thin strands of tissue (Diagram 1, H). The 
epimatium ripens into a thick firm coat

P. spicatus , unlike any other member of the genus, with a very few 
exceptions, possesses a long loose cone of many ovules somewhat distant
