median of the three larger bundles supplies the bract of the fertile 
sporophyll; each of the lateral bundles twists so as to lie with xylem 
facing the bract bundle, then the two unite into one bundle which 
proceeds into the scale. The single bundle increases in size, and 
on nearing the chalaza of the ovule breaks into three; at the base 
of the ovule each of the lateral branches curves over and passes 
downward in the tissues of the scale flanking the ovule. The 
median bundle proceeds slightly farther, then curves over the base 
of the ovule, and at the same time breaks into two branches which 
pass downward in the portion of the scale on the dorsal side of the 
ovule. The recurved branches of the scale supply fork so that

in cross-section a ring of bundles with xylem facing outward 
surrounds the ovule. 
In another species of Podocarpus investigated the scale bundle 
divides into two instead of three branches. Each of these two curves 
at the chalazal end of the ovule and passes downward, one at each 
side of the ovule. The crests of the two curves are connected by 
irregular xylem cells, and a strand of similar tissue extends from 
each crest outward into the protuberance on the scale behind the 
vule. 
Phyllocladus alpinus (figs. 183-186) consists of a globose stro- 
bilus of few sporophylls. The ovule is sessile in the axil of the 
bract. The vascular supply to the bract springs from the base
