tendency to ever assume what should be its natural hue. Some 

 specimens sent to me prove the species to be the common dwarf 

 blueberry (Vaccinium Pennsylvamcum) . Since a rather ex- 

 tended search in the Manuals give no hint that pink berries have 

 been observed in this species, and since this form is better handled 

 by giving it a name, Dr. Angell suggests that it be called Vac- 

 cinium Pennsylvanicum forma rubrum. In all respects, except 

 color, the form is like the species. — IV il lard N. Clutc. 



Effect of Environment on Trees. — There is considerable 

 evidence in the acclimatization of trees that the power of environ- 

 ment is very great. A moment's consideration of the powerful 

 influence of a temperate climate on the phases of vegetation is 

 alone sufficient. There are instances which seem to point to the 

 possibility of a new periodicity, without the loss of the old one, 

 being produced by a change of climate. One case of more than 

 usual interest is given where the behavior of Acacia dcalbata, 

 indigenous to New South Wales, Victoria and Tasmania, has been 

 entirely changed by the climate in the Nilgiris. The facts are, 

 that in 1845 and up to about 1850 the trees in the Nilgiris flowered 

 in October, which corresponded with the Australian time, but 

 about i860 they were observed to flower in September; in 1870 

 they flowered in August ; in 1878 in July ; and in 1882 they began 

 to flower in June, this being the spring month in the Nilgiris, 

 corresponding with October in Australia. It therefore takes 

 nearly 40 years to regain its habit of flowering in the spring, i.e., 

 to become perfectly acclimated. I am also informed that the 

 English oaks now growing at Johannesburg further illustrate this 

 point, since they begin to drop their leaves towards the end of 

 May, remain bare until near the end of August, when new leaf 

 appears, to be followed by flowers which ripen into fruit by 

 Christmas. — Indian Gardening and Planting.
