 M. rubra, Linn. * (Eng. 1629.) 

 Mentioned by Downing as early 

 as 1845 as an attractive tree 

 under cultivation. An early 

 record, apparently, of the cul- 

 tivation of Morus rubra is 

 given by the botanist, Fred- 

 erick Pursh, in 1806 or 1807, 

 in an entry in his journal for 

 July 9, while he was in the 

 vicinity of Cayuga Lake, N. 

 Y. "Morus rubra frequent. 

 On one or two farms I observ- 

 ed the mulberry cultivated in 

 orchards, may be for the raising 

 of silkworms, as the trees were 

 low and planted in regular 

 close rows." It is not certain 

 whether Pursh meant to say 

 that M. rubra was cultivated, or 

 that the common garden mul- 

 berry occurred in the orchards. 



Planera. Species two; North 

 American. 

 P. aquatica, Gmel. * (Eng.
