Fig. 419. Medullosa Leuckarti. Diagrammatic sketch of stem showing longi- tudinal and transverse sections: for explanation see text. (After Weber and Sterzel.) the longitudinal faces. The steles are shaded obliquely in the longitudinal sections, and in the three transverse sections. A, B, C, the primary xylem (partial pith) is black and the enclosing secondary vascular tissue radially shaded. The whole block is 9 cm. in length and 6 cm. broad. Only a part of the axial region is shown internal to the peripheral snake-rings and in it are the star-rings S, S, b, and c. Outside the main steles is the narrow Weber and Sterzel (96) B. p. 95, PI. ix. Solms-Laubaoh (97)..
