1915] AASE—M EGASPOROPHYLLS OF CONIFERS 303 
In a species of the subgenus Eupodocarpus (figs. 171-182) the 
ovule-bearing branch is a dwarf lateral branch bearing at its tip 
one and occasionally two fertile sporophylls, and a few small bracts 
some distance below. The single inverted ovule is imbedded in 
the tissues of the ‘‘epimatium,” which there is evidence for believing 
to be homologous with the ovuliferous scale in other conifers. At 
maturity the portion of the fruiting branch between the fertile 
sporophylls and the upper sterile bracts becomes fleshy.

The vascular anatomy was investigated only in cases of one 
fertile sporophyll. The vascular supply of the branch axis, after 
the traces to the sterile bracts have gone out, consists of three 
small and three large bundles. The median of the three smaller 
bundles enters what in the young stages appears like a bract 
opposite the fertile sporophyll; the two small lateral bundles bend 
in the same direction as the small median bundle, then end. The
