ZINGIBERACE^. 



Thalia dealbata Roscoe. Sana Bois Mountains. July. No. 90. 



This plant has only the iufloresoeuce '^ dusted ov^er with powder." Further, 

 Mr. Sheldon reports this iis 7-10 feet high, when, according to Chapman, p. 

 465, it is usually only 3-5 feet high. There are two other specimens of this 

 species in the National Herbarium, Dr. Bigelow'a Rio Grande plant, collected 

 in 1853 near the Choctaw Agency, and Elihu Hall's Texan plant No. 629. Hall's 

 plant, however, differs from Bigelow's and Sheldon's in that it has a ring or 

 beard of hairs on the raohis at the base of each llower, while the others are 

 glabrous at that point. Some close field work is necessary to reconcile and 

 explain these discrepancies.
