only a very small area adapted to their needs. Other plants of 
northern distribution will undoubtedly prosper here. Several 
plants of the pink bog orchid (Arethusa) have been given by Mr. 
F.C. Seymour, to supplement the single specimen which we have 
had in previous years. Most of the plants native to our area are 
now established. Some, as for example, many native orchids, the 
woodland Lycopodiums, and the species of Polygala, seem to be 
practically impossible to grow under city conditions.
