11. Dillenia L. — Flowers 5-merous. Sepals imbricated, spreading, 

 persistent, becoming fleshy around the fruit. Petals much longer, 

 imbricated. Stamens co , nearly free; anthers linear; cells adnate, 

 dehiscing by submarginal clefts. Carpels 5-co , adhering to the 

 axis, united to each other only by the ventral margin, otherwise 

 free ; styles as many, stellately reflexed, stigmatiferous internally. 

 Ovules CO , in 2 rows, subhorizontal. Fruit indehiscent, subbaccate 

 5-Go - celled ; seeds imbedded in pulp or pulpless, glabrous or hairy 

 at the margin, exarillate. — Trees ; leaves large, of parallel penni- 

 venation ; flowers solitary or fascicled^ lateral or terminal {tropical 

 Jsia, Australid). See p. 106. 



12. "Wormia Eottb. — Sepals 4-0, more rarely 10-15, unequal,

 with erect linear anthers dehiscing by terminal pores or short

 unequal, or the 5 innermost much the longest, spreading recurved. 

 Carpels 5-co (of BiUenia), cohering only on the inside, co - ovulate ; 

 when ripe dehiscing internally or indehiscent ; styles as many, free 

 spreading. Seeds arillate. — Trees or shrubs ; leaves broad, of parallel 

 pennivenation ; petioles dilated, wings deciduous ; flowers large, 

 solitary, or more frequently grouped in often unilateral terminal 

 spurious racemes {trojncal Asia, Oceania, Madagascar). See
