 — In cultivation in 

 England before 1879. By some botanists this is considered a distinct spe- 

 cies, but it is apparently only a variety due to certain soil conditions; it 

 occurs in lakes, ponds, and small rivers, apparently always over a clay subsoil. 

 Var. pendulum, Carr. ( T. distichum sinense pendulum. Loud. Glyptostrobus 

 pendulus, Endl. G. sinensis, Hort.). Weeping Pond-Cypress. A form of 

 the preceding variety with pendulous branches.

 Cypress. Similar to the preceding species : taller evergreen tree, occasionally 

 170 feet high with a trunk 20 feet or more in diameter: leaves shorter, ob- 

 tusish and mucronulate, falling with the branchlet the second year: staminate 

 panicles and cones larger. Flowering in autumn. — Introduced to Italy in 

 1838 and occasionally cultivated in California. 



The closely related Chinese genus Glyptostrobus is often united with 

 Taxodium, but it differs in its elongated not peltate cone-scales. The only
