18 cxxiiic. MORACE^ (Reudle). 



often curved, with generally thick flat or folded, often very unequal 

 cotyledons. — Trees or shrubs, more rarely perennial or annual 

 herbs, with a milky juice. Leaves alternate, rarely opposite, simple, 

 generally penninerved, in the ArtocarpecB sometimes palminerved ; 

 stipules 2, lateral and persistent or caducous, or axillary, leaving a 

 scar encircling the stem. Flowers small, in dense cymes which 

 often through union of the axis form heads, discs or hollow receptacles ; 

 female flower sometimes solitary. 



Species about 1000, widely distributed in temperate and tropical regions. 



The Bread-fruit tree, Artocarpiis incisa, Linn. f. [A. communis, Forst.], is 

 according to Welwitsch cultivated in gardens at Freetown, Sierra Leone. 

 Engler records it also from Zanzibar, the Cameroons and Loango, where it is 

 usually planted in the streets. Welwitsch (cf. Hiern in Cat. Afr. PI. Welw. 

 i. 1022) also records A. integrifolia, Linn, f., from the island of St. Thomas, 

 where it is " wild here and there, and cultivated in both the coast and 

 mountain regions of the island. . . . The inhabitants call the tree * Jaca ' 

 or 'Jacca.'" Engler records the same species from Zanzibar and German 

 East Africa. The name *' Bread-fruit " is also applied in Africa to Treculia 

 africana. 



Artocarpus differs from Treculia in its usually monoecious flowers, and its 

 receptacles devoid of an involucre of bracts at the base. The fruits of both 

 genera are used as food.

 Bracts forming a ring round the edge of the 

 receptacle.
