 Pot herbs. 



Among the plants used in Guam for golae (greens or pot herbs, Spanish " verdura)," 

 are severel species of Amaranth us called "kelites," "kuletes," or "bledos;" Cheno- 

 podium album, also called "kelites" or "cenizo;" Indian mustard (Brassica juncea) ; 

 purslane or "verdolaga" (Portulaca oleracea), and "chara" (Sesuvium portulacas-

The value of- pot herbs or ' ' greens " as a preventive and cure for scurvy has long 

 been recognized, and there can be no question that such food is necessary from time 

 to time to keep the human body in good condition. The value of this element in 

 diet has been discussed in a paper by Mr. Frederick V. Coville. ffl 



In addition to the plants above mentioned the natives of nearly all the islands of 

 the Pacific eat the young leaves of the taro (Caladium colocasia), which must be 

 thoroughly cooked to remove the acridity of their natural state. & These leaves are 

 either boiled like spinach or they are prepared with the expressed creamy juice of 

 the coconut and baked in native ovens. In Samoa this dish is called "palusami." 



Among the trees which furnish edible pods, leaves, and flowers are the marunggai, 

 or horseradish tree (Moringa moringa), and the leguminous katurai (Agati grandi-
