The seeds afford an excellent substitute for foreign coffee. Being roasted in the same manner, they 
very much resemble it in colour and flavour. When carefully prepared, they possess much more of the 
aroma of coffee than is to be found in any of the leguminous or gramineous seeds that have been treated 
in the same way. The larva of Apamea fibrosa, (the Crescent,) feeds on it.
