NOTE OF CORRECTION. 



In Inventory 42. riate I, opposite p. 16, was printed a photograph supposed 

 to represent acorns of S. P. I. No. 39723, Qiiercus insignis Martens and Galleotti. 

 Dr. William Trelease has called our attention to the fact that these acorns are 

 Q. cyclotalanoides Trelease. We here publish Plate XI, from a photograph of 

 the true Q. insignis, with a corrected legend. The legend under Plate I in 

 Inventory 42 should read : 



"Acorns of Quercus cyclobalanoidcs Trelease, the Mexican ring-scaled white 

 oak, closely related to Q. insignis; collected in the State of Chiapas, by Dr. C. A. 

 Purpus. Photographed, natural size, by Mr. E. L. Crandall, Washington. D. C, 

 March 14, 1914 (P13834FS). No S. P. I. number was assigned to these acorns."
