Notes on the Anatomy of Stangeria paradoxa. 2i 
branches and anastomoses resulting in a ring of about nine bundles 
entering the petiole. 
The two atypical cases, both of which were near the top of the 
stem were (1) a girdle with only two accessory bundles from the 
main ring, and (2) a leaf-supply consisting of three bundles coming 
straight from the stem stele and branching only on the side towards 
the leaf-base (Fig. 4). 
Fig. 1*. —Thick section of Stangeria stem, cleared and stained, showing 
leaf-trace bundles in the cortex. (N.B.—The thicker a line the nearer to the 
top of the section is the bundle which it represents). 
Figs. 2 and 3.—Normal type of vascular supply to leaf. 
Fig. 4. — One of the two abnormal leaf-trace systems. 
The leaf-bases are only slightly above the point of issue of the 
bundles from the central cylinder so that, the stem being fairly 
thick, the bundles pass out almost horizontally, but the internodes 
being very short, one sees in any transverse section, bundles of two 
or three leaf-systems (Fig. T : ). 
These bundles in the cortex were seen in section to be made 
up of centrifugal xylem and phloem often accompanied by mucilage 
canals. An obvious cambium is present and the wood is probably 
mostly secondary.
