Newspaper Botanv. — The Observer (April 3) makes a pretty 

 addition to our English plant-names. Writing of Battersea Park, it 

 speaks of the "formal garden is half -surrounded by five varieties of 

 poplar — the shapeliest, the arbelia — whose buds and catkins are a 

 week or more in advance of all such trees in the country round 

 London." 



The following, from the Times of June 1, is not only an interest- 

 ing addition to the popular Mora of the tombs of the Egyptians but 

 an indication that the New World, whence the plant ( Ipomcea 

 purpurea) comes, must have been known to that people at a date 

 long before Europe was acquainted with its discovery : — " A morn- 

 ing glory seed, reputed to be 5000 years old, has been brought to 

 Baltimore and planted in the garden of Mrs. W. Champlin Robin- 

 son, in Green Spring Valley. The seed is one of 12 found in the 

 hand of a mummy of a young Egyptian girl, which was recently 

 removed to the United States. Ten of the seeds have already been 

 planted, and all of them germinated. — Renter."
