purplish, on stalks about | in. long ; scales few, four-sided, 

 narrowing abruptly to a long, slender stipe, breaking away 

 irregularly as soon as ripe. Seeds irregularly triangular, with 

 thick, horny, warted coats. 



Var. pendulum, Carriere. (T^ig. 109.) 

 Upland Cypress. 



Taxodiuin disticliiim, var. imbricaria, Sargent ; Glyptostrobus pendu- 

 lus, Endliclier. 



Differs from the type in its smaller size, denser habit, stiffer, 

 more erect main branches, and shorter, narrower, often scale- 

 like leaves, which are closely pressed to the twigs except at the 

 apex. It is usually found in drier situations than the type. 



Var. tnucronatum. 

 Mexican Cypress. 



Taxodiiim mucronatum. 



Differs from the type in being deciduous, semi-evergreen, or 

 evergreen, according to situation, in its relatively longer male 

 inflorescences, and in the time of flowering, which is autumn. 

 There appear, however, to be intermediate forms, and it has 

 more claims to varietal separation from a geographical than from 

 a botanical standpoint. It is more tender than the type, and 

 should only be planted in the warmest parts of the British Isles. 



T. distichmn is closely allied to Glyptostrobus heterophyllus, 

 but differs in the cones and seeds. The cones of Glyptostrobus 

 have stalks |-| in. long, are distinctly pear-shaped or obovate, 

 and have smaller and thinner obovate scales. The seeds of 

 Glyptostrobus also are oval or oblong, -^-\ in. long, thin-coated, 

 and terminated by a wing | in. long. 



The deciduous cypress, which is one of our most beautiful 

 conifers, is widely distributed in wet ground from Florida, 

 through the Gulf States, to Mexico, where it is represented by the 

 var. Tnucronatum. It extends northwards along the Mississippi 

 Valley to Missouri and Indiana. In some regions it forms dense, 

 practically pure stands, elsewhere it is mixed with Nyssas and 

 other trees. The species was introduced by John Tradescant 

 about 1640, and was described by Parkinson in his Theatrum 

 Botanicum, p. 1477. 



Wood soft, weak, straight-grained, easily worked, not subject 

 to serious shrinkage, and has a characteristic sour odour. The 

 sap wood is white or yellowish white, and the heart wood varies 

 from red to almost black. It is comparatively free from flavour- 

 ing matter, is not liable to insect attacks, and is very durable in 

 wet places. For greenhouse construction, vats, cooper.ige, water- 

 tanks, water-pipes, general carpentry, furniture, fencing, ventila-
