 figs. 79, 80, ante. Trausverse section showing all the 

 features described. The large vessels are very notice-

 chyma, which are not very well preserved, are beat 

 seen where there are locally dark-stained patches. 



V. 5452 c, V. 5452 e. Transverse sections, similar to the above ; 

 a dark patch on the left side of slide e shows the 

 tissues unusually well.

 vol. 203, 1912, text-Hg. 6, p. 92 ; and text-fig. 81, ante. 

 Radial, but partly obliquely tangential, section. The 

 large vessels and high medullary rays can be recognised. 

 Tyloses can be seen in several of the vessels and also 

 very pretty septate fungal hyphae. On some of tho 

 vessel-walls the outline of the adjacent elements and 

 the pits between them can be seen. 



V. 5452 d. Obliquely tangential section of the above, rather more 



poorly preserved.
