Okdbh II. DILLENIACE^. Gen. PJ. i. 10. 



Trees or slirab3, rarely herbs^ not; arotriatic, witK simple alternate penni- 

 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 oo , hypogynous, free. Anthers basifixed, 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. 



Remarhalle anatomical characters : Hairs never giaiidiilarj always one-celled, some- 

 times stellate, and surface of leaves often rougli, tlie roughness being caused in some 

 species by bhort thick-walled liaiib ; in otliers (species of tlie American genus Our at ell a ^ 

 wliicli 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 burface. 

 Medullary rays in the wood very broad ; hence on a radial section the remarkably 

 mottled appearance of the wood. The wood fibres always have bordei-ed pits.

Trees with large dentate or crenate leaves, crowded at the ends of thick
