Select Plants for Industrial Culture and 



in recently cleared forest-ground, not like Cocksfoot-grass and 

 particularly Rye-grass apt to be attacked by caterpillars ; also 

 suited for suppressing bracken-ferns after they have been burnt 

 down. Recommendable also for newly drained land. Bears con- 

 tinued grazing off extremely well. Also thrives according to the 

 Rev. H. Kempe in the hottest and driest regions of Central 

 Australia. Particularly dangerous for the spreading of the 

 ordinary rust-fungus, Puccinia graminis (Uredo linearis). The 

 chemical analysis, made in full spring, gave the following results : 

 Albumen, 2 '20 ; gluten, 4' 11 ; starch, O72 ; gum, 3 '08 ; sugar, 4'56 

 per cent [F. v. Mueller and L. Rummel]. 



Holcus mollis, Linne. 



Creeping Softgrass. Of nearly the same geographic range and 

 utility as the preceeding species. Particularly adapted to sandy 

 forest-land. Grown in Norway to lat. 63 7/ [Schuebeler]. 



Holoptelea integTifolia, Planchon. (Ulmus integrifolia, Koxburgh.) 



The Elm of India, extending from the lowlands to sub -alpine 

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

 deciduous. 



Hordeum andicola, Grisebach. 



Argentina. Pronounced by Prof. Hieronymus as an excellent 

 pasture-grass of the Sierras. 



Hordeum deficiens, Steudel. 



The Red-Sea Barley. One of the two-rowed barleys, cultivated 

 in Arabia and Abyssinia. Allied to this is'H. macrolepis (A. 

 Braun), a native of Abyssinia. 



Hordeum distichon. 0. Bauhin.* 



Wild from Arabia to Central Asia [A. de Candolle]. The 

 ordinary Two-rowed Barley. Cultivated as early as the stone-age 

 [Heer]. 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. An 

 unbearded variety, called the Berkeley-Barley, was recently raised 

 by Professor Hilgard in California ; it approaches the Nepal- Barley, 

 but the husk is adherent. This new sort is not so liable to the 

 attacks of rusts-fungs as many other varieties. Dry barley-flour, 

 heated to the temperature of boiling water during several hours 

 under the exclusion of atmospheric air, constitutes Hufeland's 

 meal for invalids. Barley-culture can be carried on even in 

 alpine regions. Marly and calcareous lands are particularly fit for 

 rearing this cereal grass. It resists moderate spring-frosts. As 

 much as 100 bushels of Cape-barley have been obtained from an 

 acre of land in volcanic soil of Victoria as a first harvest.
