Dr. A. J. A. Fredholm gave "Notes on the Flora of 

 Jamaica," and illustrated his observations with a large set 

 of dried specimens collected during several visits to the 

 island. The characteristic plants of the shore sand region, 

 of the coral rock formations,, of the wooded mangrove 

 swamps, of the toot-hills, and of the high lands were treated

 throsin, followed by thyonin of saturated strength.

 from the Buist and Harrison funds. 



The director of the University Garden exhibited seed- 

 lings of the parasitic Lauraceous plant, Cassytha Hliformis, 

 grown from seeds gathered by him during the recent Florida 

 trip. He compared it with the seedling dodder plant, and 

 pointed out how, unlike most flowering parasites, both of 

 these exhibited a wide range of choice in parasitic habit, 

 though Cassytha apparently excelled the dodder, since it 

 was observed to be parasitic on such widely different genera, 

 as Pteris, Pinns, Zamia, Qiicrcus and many of the higher 

 genera of flowering plants.
