The author discusses the identity of Linum hispanicim:, Mill. 

 (Gard. Dict. ed. VIII. n". 7) and L. an git st ifoUitni, Uxxds., and d'\i^AQ,rQes 

 with Williams (Prod. H. Brit. p. 485) who regards them as the -^ame. 



As the result of his investigations he reduces the former to L. 

 angliciim, Mill. and the latter to L. hienne, Mill.. giving the füll 

 synonymy of both these species. J. Hutchinson (Kew). 



Bessey, E. A., The hammocks and everglades of southern 

 Florida. (Plant World XIV. p. 268—276. f. f— 12. Jan. 1911.) 



The Vegetation of the pine woods of the region is first discussed 

 and then that of the hammocks which is found entirely different 

 from the regions further north. The author notes the abruptness 

 of the transition from the pine woods to the hammocks and concludes 

 from his studies that the genesis of the hammock is that somewhere 

 in the pine woods a few small shrubs, or persimmon, Diospyros 

 virginiana, with other broad-leaved species begin to grow in a 

 sheltered place where the air is somewhat moister. Here once 

 having obtained a hold, this type of Vegetation increases until a 

 hammock is formed. The paper concludes with a general description 

 of the Vegetation of the Everglades. Harshberger.
