FAMILY 6. RHIZOPHORACEAE. MANGROVE FAMILY. 



Shrubs or trees. Leaves usually opposite: blades entire or toothed. 

 Flowers perfect, solitary or variously clustered. Calyx of 3 or 4 valvate 

 sepals. Corolla of 3 or 4 thick petals. Androecium of twice or thrice as 

 many stamens as sepals, or of 4 times as many. Gynoecium of 2-5 united 

 carpels. Ovary inferior, at least partly so. Styles mostly united. Fruit 

 a leathery berry crowned with or surrounded by the calyx. 



1. RHIZOPHORA L. Evergreen trees. Leaf-blades leathery. Flowers 

 2-several in peduncled clusters. Sepals 4, leathery. Petals 4, leathery. 

 Stamens 4-12. Ovary 2-celled, produced into a fleshy cone at maturity. Fruit 

 pendulous, the seed germinating and sending out a long radicle before the 

 fruit falls. 



1. R. Mangle L. Shrub, or tree becoming 10 m. tall, forming impenetrable 

 thickets on salt or brackish shores: leaf -blades elliptic to elliptic-obovate, 5-15 

 cm. long: sepals lanceolate, about 10 mm. long: petals pale-yellow, linear or 

 nearly so: fruits 2-3 cm. long, the precocious radicle clavate. Salt and brack- 

 ish shores and coastal hammocks. F. K. (Ber., Bah., Cuba, Ant.) MANGROVE.

 Androecium of as many stamens as the sepals or twice as many. Gynoe- 

 cium of several, usually 4, united carpels. Ovary 1-6-celled, usually 4- 

 celled, inferior. Fruit capsular or nut-like. 



Fruit a many-seeded capsule. 



Hypanthium not prolonged beyond the ovary.
