Cola acuminata is a tree with lanceolate or obovate, acuminate, 

 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 glomerata

leaves of Pterospermum Acerifolium. The inner bark of Fremon- 

 tia calif arnica is used for purposes similar to those of elm bark. 

 Mucilage is also found in the following genera : Pentapetes, Wal- 

 theria, Guasuma, Helicteres, and Sterculia. Tannin is found in 

 the bark of Guazuma ulmifolia of South America. An oil is 

 manufactured from the seeds of Sterculia fcetida of the East 

 Indies and Cochin China. The seeds of a number of species of 

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

 has been suggested as a substitute for silk.
