Dear Sir; — 



Your letter of December 11 and package have "been received. 

 Your Panicum A I take to he P. tennesseense . The rosette blades and 

 the upper surface of the culm hlades are smooth. The plants are 

 much less freely "branching, however, than P. tennesseense ought 

 to be. If your B was upright it must he P. dichotomum, the 

 unusual form with pubescent nodes; if prostrate or nearly so I 

 think it must he P. harhulatum. The puherulent sheaths of the 

 "budding rosette point to the latter species. 



I am very sorry that Dr. Robinson is sick and sincerely 

 hope he will soon recover. It is to he hoped he will he perfectly 

 well in time to attend the A.A.A.S. meetings here. I am planning 

 "housecleaning" the herbarium here to he ready for company. Are 

 you not coming? Yoxi would find many friends and much of interest 

 here I feel sure. 



Euphorhia cyparissias fruits abundantly in Illinois and is 

 common there, especially about cemetaries. For some unimaginable 

 reason people seem to plant the things on graves. 



Prof. Hitchcock's last letter written from Salvador, said 

 he would not be back until after Christmas. Yours ^ respectfully,
