Pennsylvania for Sesstons 1901-1903. xli 
tion of Miss Dock from the Second Vice-Presidency, owing 
to residence at a distance from the city, the Council had 
unanimously filled the vacancy by appointing Dr. Henry 
Leffmann to the office. 
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 
of in succession. 
Mr. Henry S. Conard described and practically illustrated 
“A Method of Double Staining in Plant Cytology,” arranged 
by Mr. R. C. Banes, and which consisted in the use of ery- 
throsin, followed by thyonin of saturated strength. 
Miss H. Boewig exhibited recent additions to the Botan- 
ical Library, including the twenty-three volumes of the 
“Flore des Serres,’ Andrews’ “Botanical Repository” and 
Hooker’s “Flora of British India,” obtained by purchase 
from the Buist and Harrison funds. 
The director of the University Garden exhibited seed- 
lings of the parasitic Lauraceous plant, Cassytha filiformts, 
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, Pinus, Zamia, Quercus and many of the higher 
genera of flowering plants. 
March 29. In the absence of the Acting President, Dr. 
Henry Leffmann, Second Vice-President, occupied the chair. 
Mrs. J. D. Chandler spoke on “Some Unusual Plant-foods.” 
Rare condiments, candied preparations, salads and pot 
herbs, as well as the plants from which these were obtained, 
were described.
