 entire, petiolate leaves. The flowers are yellowish, unisexual, 

 and in small axillary clusters, frequently arising from the old 

 wood ; the fruit consists of five follicles, each containing 4 to 8 

 seeds. The seed is made up of two large, fleshy cotyledons. They 

 have much the same constituents as Cacao, but the proportions 

 of these dififer. (See Cola.) The leaves of Waltheria glomcrata

 Sterculia are edible. Ahromn angusta of India yields a fiber which
