Scrophulariaceae. 405 



In the concavities on the under surface of the teeth I found 

 the epidermis covered with crystal aggregates, which proved 

 to consist of calcium-carbonate. — The same observation 

 has been made by Wettstein (1. c. p. 19). I have sometimes 

 also found crystals of the said substance in the cells of the 

 large glandular hairs, as shown in Fig. 14, E. 



The pahsade-tissue and spongy parenchyma were rich 

 in chlorophyll-grains; and such were also found in the epi- 

 dermis of the lower surface.
