the most eligible grasses, yielding an abundant crop ; it is 

 however, rather disliked by cattle as well as horses. 



Holcus mollis, Linne. 



Of nearly the same geographic range and utility as the pre- 

 ceding species. Particularly admissible for sandy forest land. 



Holoptelea integrifolia, Planchon. (Ulmus integrifolia, Rox- 

 burgh) . 



The Elm of India, extending from the lowlands to Sub-Alpine 

 regions. A large tree, with timber of good quality. Foliage 

 deciduous. 



Hordeum deficiens, Steudel. 



The Red Sea Barley. One of the two-rowed Barleys, culti- 

 vated in Arabia and Abyssinia. Allied to this is H. macro- 

 lepis (A. Br.), a native of Abyssinia. 



Hordeum distichon, Linne.* 



Central Asia. The ordinary two-rowed Barley. To this 

 species belong : the ordinary English Barley, the Chevalier, 

 the Annat, the Dunlop, the Long-eared, the Black, the Large, 

 the Italian, and the Golden Barley, along with other kinds. 

 A variety with grains free from the bracts constitutes the 

 Siberian and the Haliday Barley, which, however, is less 

 adapted for malt. Dry barley flour, heated at the tempera- 

 ture of boiling water during several hours, constitutes Hufe- 

 land's meal for invalids. Barley culture might be carried on 

 in many Alpine regions. Marly and calcareous lands are 

 particularly fit for its culture. It resists moderate spring 

 frosts. 



Hordeum hexastichon, Linne.* 



Orient. The regularly six-rowed Barley. This includes 

 among other varieties the Red, the Scotch, the Square, and 

 the Bear Barley. Seeds less uniform in size than those of 

 H. distichon. The so-called skinless variety is that in which 

 the grain separates from the bracts. Langethal observes that 

 it is most easily raised, requires less seed grain than ordinary 

 barley, has firmer stems, is less subject to the rust disease and 

 to bending down. 



Hordeum secalinum, Schreber.* (II. nodosum, Linne ; H. pratense, 

 Hudson.) 



Europe, North and Middle Asia, North America. Perennial,
