1078 ARBORETUM ET FRUTICETUM BRITANNICUM. 



Leaves simple, alternate, exstipulate, deciduous ; 2 -ranked, linear 

 Flowers yellowish, powdery, inconspicuous. 



Lofty deciduous trees, natives of the southern part of North America ; sepa- 

 rated from the genus Cupressiis, principally because the male catkins are dis- 

 posed in loose spreading bunches, instead of being solitary and terminal ; and 

 because the female catkins are roundish and scaly, like the male, and each 

 scale has only 2 perfect flowers. The genus is also distinguished by the 

 embryo having from 5 to 9 cotyledons. The species are generally propagated 

 by seeds, and the varieties by cuttings, layers, or inarching.

plates of this tree in Arb. Brit., 1st edit., vol. viii. ; and our fig. 2006. 



Spec. Char. y Sfc. Leaves 2-rowed, flat, deciduous. Male flowers leafless and 

 panicled. Cones somewhat globose. (Willd.) A lofty deciduous tree. 

 Florida, and on the Delaware and Mississippi, in swampy ground. Height 

 1 00 ft. to 150 ft.; in England, 50 ft. to 80ft. Introduced before 1640. 

 It flowers in May, and the cones, which are brown, are ripened in the spring 

 of the following year. 



Varieties. 



t T. d. 1 patens Ait. Hort. Kew. ed. 2. v. p. 323. Leaves approxi- 

 mate, and strictly 2-rowed. This is the most common form. 

 T. d. 2 nutans, 1. c. T. d. pendula 

 Loud. Hort. Brit. Leaves much 

 longer than those of the species, and 

 drooping, but more remote and thinner 

 in texture, with a tortuous curly ap- 

 pearance when they first appear in 

 spring. A specimen of the early shoots 

 is shown in fig. 2005.

How far it differs from T. d. nutans, or whether it differs at all, we 

 are uncertain. H. 8., in 1837.

 The deciduous cypress is one of those trees that sport exceedingly in the 

 seed-bed ; and, hence, wherever a number of them are found growing to- 

 gether, scarcely any two appear to have precisely the same habit. This is 

 strikingly the case at White Knights, where there are several scores of 

 trees, presenting a variety of forms and foliage almost as great as their number. 

 They may all, however, as well as those enumerated in the above list, be 

 reduced to the following four forms. 1. The species, or normal form, in 

 which the branches are horizontal or somewhat inclined upwards. 2. T. d. 

 pendulum, with the branches pendulous. 3. T. d. nutans, with the branches 

 horizontal, and the young shoots of the year pendulous ; the leaves being 

 twisted and compressed round them in the early part of the season, but 

 fully expanded, like those of the species, towards the autumn. Most of 

 these shoots have their points killed every winter, and many of them are 

 entirely destroyed. 4. T. d. tortuosum pendulum, with the leaves on the 

 young shoots tortuous, and the branches pendulous. There is a very 

 elegant specimen of this tree at White Knights. With respect to the T. 

 sinense of cultivators, we have not been able to discover in what it differs 

 from T. nutans ; and of T. d. excelsum we have only seen very small plants.
