a reprint from one in the possession of Mrs. West. This 
again was a photo-reproduction from one in the rooms of 
the Pennsylvania Horticultural Society. The photograph

over the Bartram Memorial Library of the Botanical De- 
partment. He next exhibited a species of Phoradendron, 
and a varied collection of living plants, the former having 
been found by Mr. Roberts Le Boutillier on large juniper
