LIRIODENDRON 



Liriodendron} Linnaeus, Sp. PL 535 (1753); Bentham et Hooker, Gen. PL i. 19 (1862). 



Trees, several extinct and two living species, belonging to the Natural order 

 Magnoliaceae, with deciduous, alternate, stalked, saddle-shaped, or lyrate leaves. 

 Flowers : solitary, terminal, stalked, regular, enclosed in bud in a 2-valved spathe, 

 which falls off when the flower opens. Floral receptacle : cylindro-conic, bearing 

 from below upwards 3 imbricated petaloid sepals, 6 petals imbricated in two rows, 

 numerous stamens, with anthers dehiscing outwardly by longitudinal slits, and a 

 spindle-shaped column of numerous densely imbricated independent carpels. Each 

 carpel is a i -celled ovary, containing 2 ovules, and terminating in a style with 

 stigmatic papillae at its apex. Fruit : a cone of samarse, falling off the receptacle 

 when ripe, each containing i or 2 seeds. 



Liriodendron appeared in the Cretaceous epoch, and numerous fossil species have 

 been found in North America and Europe in the Tertiary period. Of the two now 

 living, one occurs in the eastern half of the United States and Canada, the other is 

 a native of Central China. 



' Liriodendrum is the spelling used by Linnaeus in his earlier descriptions of the genus in Corollarium Gen. PI. 9 (1737), 

 and Hort. Cliff. 223 (1737) ; but the form given above is the one now always adopted.
