Floiuering Plants. — Collections acquired during the year 

 by donation and purchase have been mounted and incorporated 

 wholly or in part. Outstanding specimens have been mounted

 Ericaceae, and other families of Gamopetalse, Orchidacese, 

 Graminese, .and other families of Monocotyledons ; and the 

 selection, determination, and incorporation of the early
