308 sturtevant's notes on edible plants 



merated by Thunberg among the edible plants of Japan. It is cultivated in Scotland as 

 a spring crop and in Ireland as a winter crop. Nepal barley is cultivated at great eleva- 

 tions on the Himalaya Mountains and in Thibet. The seed has frequently been sent 

 to Europe as a very hardy kind, of quick maturity, but it is chiefly cultivated in botanical 

 gardens. It is a naked-seeded Epecies with much the appearance of wheat. It was intro- 

 duced into Britain in 1817.* 



H. zeocriton Linn, battledore barley, sprat barley. 



Parent of cultivated forms. This species is occasionally cultivated in Scotland, and 

 Lindley ' says it is interesting only from a botanical point of view. He says it is an 

 undoubted result of domestication. Koch * collected in the Schirwan part of the Cau- 

 casus a kind of grain which he calls H. spontaneum and regards as the original wild form 

 of sprat barley. 



Hormosippon arcticus Berk. Algae. 



This alga abounds in the Arctic regions and affords wholesome food, which is far 

 preferable to the tripe de roche, as it has none of its bitterness or purgative quality. 



Houttuynia cordata Thimb. Piperaceae. 



Himalayan region, China and Japan. The leaves of this plant are said to be used 

 as a potherb in Nepal.* In France, it is an inmate of flower gardens ^ as an aquatic. 



Hovenia dulcis Thunb. Rhamneae. raisin tree. 



Himalayan regions, China and Japan. The tree is cultivated in India for its fruit, 

 which has a pleasant flavor like that of a Bergamot pear.'' The round fruits, about the 

 size of a pea, are seated at the end of the recurved, fleshy pedimcle, which is cylindrical, 

 about an inch long, and is the part eaten.* 



Hamulus lupulus Linn. Urticaceae. bine. hop. 



Northern Eiirope and not rare in the United States, especially westward on banks 

 of streams. The scaly cones, or catkins, have been used from the remotest period in the 

 brewing of beer. The hop was well known to the Romans and is mentioned by Pliny 

 under the name lupus salictarius. Hop gardens are named as existing in France and 

 Germany in the eighth and ninth centuries, and Bohemian and Bavarian hops have been 

 known as esteemed kinds since the eleventh century. The hop was mentioned by Joan 

 di-Cuba in his Ortus Samtatis as growing in Holland prior to 1485. Hop roots were men- 

 tioned in the Memorandum ' of Mar. 16, 1629, of seeds to be sent to the Massachusetts 

 Company. The plant was also cultivated in New Netherlands as early as 1646, and in
