In tlio arrangement of the Natural families which is being followed 
in these papers (that of DeCandolle as modified by the late Mr. Bentharn 
and Sir Joseph Hooker), the family Dipterocarpeae should have preceded 
Malvaceae. Delays have, however, occurred in the elaboration of that

Sepals 5, valvate, free or connate. Petals 5, twisted-imbricate. Stamens 
ac , rarely definite, adnato to the base of the petals ; filamonts monadel- 
phous, forming a tube ; anthers oblong or reniform, cells sinuous or 
twisted, linear or annular, ultimately 1-celled bursting longitudinally. 
Ovary 2-many-celled, entire, or lobed, of 2-5 or usually more carpels 
whorled round a central axis ; styles connate below or throughout their 
length ; ovules 1 or more, curved, attached to the inner angle of each 
carpel. Fruit of dry cocci, or capsular and loculicidal, often large and 
woody. Seeds reniform or obovid, somotimos arillate ; albumen scanty,
