STYRACINE^. 



[PAKT II 



ORDER CXIX.— STYRACINEiE. 



The plants in this order best known in 

 English gardens are Styrax ojfflcinale^ the Storax, 

 and Halesia tetraptera^ the Snowdrop-tree. The 

 flowers of both are white ; those of Storax are 

 funnel-shaped, with a five-cleft limb ; there 

 are ten stamens, growing together at the base, 

 with short filaments, and very long anthers. 

 The fruit is a drupe which is nearly dry, con- 

 taining a one-celled nut, enclosing from one 

 to three seeds. The seeds have two skins, the 

 inner one like a cobweb, and the outer one 

 spongy. The bark, when wounded, affords the 

 gum called storax. Halesia has drooping bell- 

 shaped white flowers, something like those of the 



Snowdrop, (see a in 

 Jig. 189,) with four 

 petals and twelve or 

 sixteen stamens com- 

 bined into a tube at 

 the base. The fruit is 

 a dry, winged drupe, 

 which has four an- 

 gles in H, tetrapfera 

 (A), and two in H. 

 diptera ; and which 

 contains a stone or
