TAXODIUM. 383 



and Georgia, it occupies a great part of the swamps which 

 border the rivers in the lowlands, and in East Florida, Louisiana ; 

 and those parts of the marshes, where the deciduous Cypress 

 almost alone occupy, are called Cypress swamps, and cover 

 thousands of acres. The Americans call it the " Bald Cypress," 

 the " Black Cypress," and the " White Cypress," as it varies 

 very much in appearance according to soil and situation. The 

 roots of large trees, particularly in very moist situations, pro- 

 duce conical protuberances above ground, frequently from one 

 to two feet high, and sometimes three or four feet in thickness, 

 but always hollow in the centre, smooth on the outside, and 

 covered with a reddish bark, and called Cypress knees by the 

 Indians. 



There are the following varieties : — 



Taxodium distichum denudatum, Leroy. 



Branches slender, long, horizontal, or drooping towards the 

 ends, irregularly, and little divided. Branchlets fringed, with 

 scattered, variable, and unequally-distant leaves. 



This variety was raised by M. Leroy, nurseryman, at An- 

 glers, in the South of France. 



Taxodium distichum fastigiatum, Knight. 



Syn. Taxodium fastigiatum, Hort. 



„ adscendens, Brongniart. 



„ Schubertia disticha imbricata, Spach. 

 „ Cupressus imbricata, Nwttall. 

 Branches short, erect, slightly spreading at the top. Leaves 

 two-rowed, and resembling those of the species. This very 

 distinct variety is a much smaller and a more compact tree, 

 with the form of a regular conical pyramid, or fastigiated 

 head. It is found in the marshy grounds along the sea-shore, 

 in Florida and Carolina, forming a small tree. 



A very distinct-looking small tree, but certainly not a dis- 

 tinct species.
