" This species is common on the slopes of the valley of Mexico, and is still 

 used by the Indians to a limited extent. Doubtless, it was of much greater im- 

 portance as a foodstuff in ancient times than it is to-day. Mrs. Nuttall has 

 planted in her garden a number of bulbs gathered on the hillsides near her 

 home and has found that they multiply rapidly and require no cultural atten- 

 tion. When in bloom, the plants are beautiful, their flowers varying from 

 yellow to deep scarlet in color. As an ornamental plant the Tigridia is already 

 known in other countries, but the use of its bulbs as an article of food is not 

 common outside of Mexico. When fully developed, the bulbs are slightly less 

 than 2 inches in diameter. For eating, they are usually boiled, or parboiled 

 and fried. When boiled they are mealy and have a very agreeable flavor some- 

 what suggesting that of chestnuts. 



" It is suggested by Mrs. Nuttall that the cacomite be given a careful trial 

 in the southern United States as a root crop. When grown from seed it re- 

 quires two seasons for the bulbs to reach maturity, but they demand very little 

 cultural attention, and the ornamental character of the flowers should make 

 the cultivation of the cacomite very attractive to those who are interested in 

 new and rare vegetables." (Wilson Popenoe.)
