138. Thymelacetz. Stem shrubby. Leaves without sti- 

 pules. Calyx inferior, tubular, often coloured. Stamens defi- 

 nite, in the orifice of its tube. Ovary with one pendulous 

 ovule. Fruit nut-like or drupaceous. Albumen none, or 

 thin ; embryo straight ; radicle superior. 



USES. The bark of the species is generally caustic ; that 

 of Daphne Laureola, the Spurge Laurel, acts as a vesicant ; 

 the succulent black fruits are dangerous. Lace Bark, the 

 liber of Lagetto lintearia, derives its name from the delicate 

 white fibres, which are tough, and easily separated by a little 

 violence. The same toughness of the fibre is found in many 

 species ; Daphne cannabina derives its name from being as 

 tough as Cannabis (Hemp).
