Family 2. CARICACEAE Dumort. 



Papaw Family. 



Trees, with milky sap, ample broad palmately 7-9-lobed leaves and 

 unisexual, or rarely perfect flowers. Calyx short. Staminate flowers with 

 a salver-shaped corolla, its tube slender; the lobes 5, valvate or convolute; 

 stamens 10, inserted in the throat of the corolla; filaments short; anthers 

 adnate to the filaments, 2-celled. Pistillate flowers with 5 distinct petals 

 and no staminodia; ovary compound, 1-celled, or sometimes imperfectly 

 5-celled, free, sessile; stigmas 5, sessile; ovules numerous, in two or many 

 series on the 5 placentae. Fruit a large fleshy berry. Seeds numerous, 

 flattened, with a roughened testa; endosperm fleshy; embryo axile. There 

 are two genera, the following composed of about 25 species of tropical and 

 subtropical distribution, and Jacaratia of tropical Africa and America, 

 which differs from Carica by having the stamens partly united.
