more precisely. It is probable that a good proportion of his 

 west Florida specimens came from St. Vincent, and if we could 

 tell which, the flora of the island would undoubtedly now be 

 well known. It is related that the doctor once was called to 

 the island to set a broken leg. As some time was consumed in 

 making the trip for the doctor and bringing him back, the 

 patient was in considerable pain upon his arrival. After the 

 leg was set and bandaged the patient requested the doctor to 

 remain with him and make every effort to relieve the pain. 

 However, Doctor Chapman, after remarking that pain was only 

 natural in such eases and he had done all he could, lost no 

 time in striking out through the woods to collect plants. 



The writer was on St. Vincent Island from January 7 to 

 January 14, and from October 30 to November 6, 1010, neither 

 period a very favorable one for plant collecting. However, 

 much was learned as to the time when mature fruits arc 

 present, and this data is presented in detail. Definite informa- 

 tion on the ripening season is usually very scarce in plant lists. 

 The only English names of plants given are a few unusual ones 

 current on the island. The list includes 239 species of specifi- 

 cally identified indigenous plants, 10 whose identity is more or 

 less in doubt, and 12 introduced species. One unidentified 

 plant not listed is Chara sp. It figures as a wild duck food 

 and is known as 'musk grass." Tuber-bearing specimens 

 have been collected in October. 



The writer acknowledges, with gratitude, his indebtedness 

 for determinations of specimens or other assistance, to a num- 

 ber of botanists including Mrs. Agnes ('base, Mr. H. H. 

 Bartlett, Dr. E. L. Greene, Professor A. S. Hitchcock, Dr. 

 John K. Small, Mr. Paul R. Standley, and Mr. Ivar Tides-
