PRESENT DISTRIBUTION OF THE TAXODIUM DISTICHIUM. 



\- • - — i- the last remnant of what was once a very cosmopolitan 

 is, it i- worth our «liil< i to consider it- presenl limitations of the form. 

 ill therefore give a brief synopsis of the present limits of the Bpecies 

 i- I have been able to ascertain them. 

 Although Bingularly limited in it< station, the swamp cypress neverthe- 

 i wider range of climate than many <>f onr foresl trees that 

 .t range of soils and of exposures. The northernmost point 

 where it now exists is centra] New Jersey. In this district it is apparently 

 in it- decadence the individuals few and much Bmaller than those which 

 lie buried in the swamps of that district Its northern limit in this district 

 i to depend upon its endurance of cold, as it is not killed by 

 much lower temperatures than it finds in the swamps of Nen Jersey. S 

 this Bpecies has ever been found in the ancient Bwamps that ar 

 lently excavated in New England, although they are said t.> l»' abund- 

 ant in New Jersey. This leads us t.i the conclusion, that Bince the last 

 il period it has never extended farther north along tlii> Bhore than 

 the last-named district 



iward from New Jersey we find it Bparsely distributed until we 

 .-..in-' t.. the <li-trii-t south of the James river. Sere we enter upon exten- 

 this tree, and it appears afterwards at any point affording 

 rable conditions for it- growth along the whole Atlantic coast 



In Virginia it does not nr much beyond the limits of the swamps thai 



lie within a height of fifty feet above tide-water. The swampy borders of 

 the inland streams are n>>t occupied by it. In this region it struggles very 

 little beyond the limits of the shore swamps. 



In the Carolinas its westerly extension somewhat increases, yet it- limi- 

 tation ti> the region within about one hundred feet above tide-water remains 

 .1 marked feature. 



I G _ i the limits of the species are again forced nearer t<> tl 

 by thi il height "t' the surface of the country. 



I Florida thi I t.> !„• common throughout the length and 



th of the peninsula. 

 I Alal M -i|-|>i the cypress follows all the Btream borders 



i farther into the uplands than on the Atlantic slope. It is com- 

 mon in all the swamps in tho*
