106 PHARMACAL PLANTS AND THEIR CULTURE. 



reports were no doubt erroneous, the poisonous effects noted having 

 been due to a fungus (ergot) found on the grass. 



The seeds of Avena fatua (wild oats), Danthonia californica (Cali- 

 fornia wild oat grass), Bromus marginatus (poverty grass), Elynms 

 triticoides (squaw grass), Sitanion elymoides (squirrel tail), Hordeum 

 murimum (squirrel tail), Hordeum vulgare (barley), Lolium temulen- 

 tum (poison darnel), and Lolium perenne (poison rye grass), are made 

 into a meal (pinole) by the Indians and eaten. 



415. Gymnocladus canadensis Lam. (G. dioica). Kentucky coffee 

 tree. Leguminosce. 



Cultivated as an ornamental tree. The seeds are said to be poi- 

 sonous. They contain a saponifiable fixed oil, a little fat, resin and a 

 glucocide. The seeds were once much used as a substitute for coffee, 

 particularly about the time of the Revolutionary War. 



416. Gymnogramma triangularis Kaulf . Golden back fern. Filices. 

 Polypodiacece. 



A native of California. Contains a ceroptene. Used medicinally

 oak; also taken internally. (U. S. Disp.) 



419. Hedera helix L. Ivy. Araliacece. 



This familiar ornamental plant, introduced from Europe, has been
