Oedek II. DILLENIACE^l. Gen. PI. i. 10. 



Trees or shrubs, rarely herbs, n it aromatic, with simple alternate peuni- 

 veined leaves and dilated petioles, often winged and sheathing at base. 

 Flowers large, bisexual, regular, white or yellow, single or incymose fascicles. 

 Sepals usually 5, persistent, imbricate in bud. Petals generally 5, deciduous. 

 Stamens mostly x , hypogynous, free. Anthers basitixed, or laterally adnate to 

 the connective. Ovary free, consisting of one or several more or less distinct 

 carpels, styles always distinct. Seeds with an arillus, albuminous, embryo 

 minute. 



Remarkabh anatomical characters: Hairs never glandular, always one-celled, some- 

 times stellate, and surface of leaves often rough, the roughness being caused in some 

 s|jiri.s by short thick-walled hairs : in others i species of the American genus < 'uratella, 

 which are used to polish wood and even metals) by siliceous concretions in the 

 epidermis, and in some by sacs filled with raphides protruding above the surface. 

 Medullar,; rays in the wood very broad; hence on a radial section the remarkabrj 

 mottled appearance of the wood. The wood fibres always have bordered pits. 



The genera San run in and Actinidia, placed by Baillon and Gilg (Engler u. Prantl.
