SOME STUDIES ON THE SEEDS AND FRUITS OF 

 BERBERIDACE^. 



BY L. H. PAMMEL, J. R. BURNIP AND HANNAH THOMAS. 



Although several papers bearing on the anatomy of different 

 organs of plants of this order have been published/ no one 

 has studied the comparative anatomy of the seeds. 



It gives us great pleasure to acknowledge the kindness 

 shown us by Drs. B. L. Robinson, J. K. Small, Mr. G. H. 

 Hicks, and Prof. C. S. Sargent for favors shown us in the way 

 of obtaining material for study and the determination of some 

 species; the free access to and use of the library of the Mis- 

 souri Botanical garden, through the courtesy of the director, 

 Dr. Trelease, and, finally, the faithful work in drawing the 

 seeds and fruits and preparing the microscopic details for the 

 engraver by Miss Charlotte M. King. 



The literature on the anatomy of seeds is somewhat meager. 

 Godfrin^ (1880) has given us an account of Berhtria sinensis and 

 B aquifolium. He states that the testa in this family are much 

 alike. His figure and description of the osteosclerid layer does 

 not agree as we have found it in the species studied. 



He gives us a very good account and figure of the epidermal 

 cells of B. aquifolium He speaks of the epidermal ceP- walls
