bract bundle; in the lower sporophylls scale and bract supplies 

 spring from the base of the gap as one large bundle which breaks 

 into three; these latter supply the sporophyll parts as described 

 before. 



Figs. 114-128. — C'ryptomeria japonica: fig. 114, longitudinal section of sporophyll; 

 fig. 115, origin of bract (ft) and scale bundles in upper part of strobilus distinct, in 

 lower part united (/«); figs. 116-125, transverse sections, further course of bundles in 

 sporophyll; bract bundle (ft) remains undivided, some of scale bundles come to lie 

 in same plane as bract bundle (figs. 121, 122); lobes of scale separate from one another 

 and from bract, each lobe receiving usually one bundle; remaining scale bundles enter 

 free portion of bract (figs. 123, 124); bundles end in large irregular tracheids; ovules 

 not represented; X7; fig. 126, longitudinal section of young strobilus, scale (5) appears 

 as small lobes between bract (B) and ovules (0), X16; fig. 127, transverse section of 

 young sporophyll, showing bract (B), four lobes of scale (5), and ovules (0); fig. 128, 

 transverse section of one of uppermost sterile sporophylls, showing outgrowths similar 

 to lobes of scale in fig. 127, X34.
