whicli actually perishes under lengthened inundation, but 

 which is less productive. The Glutinous Rice, which suc- 

 ceeds as well in wet as almost dry places, and produces black 

 or reddish grains. In the rich plains of Lombardy, irrigated 

 from the Alps, the average crop is estimated at forty-eight 

 bushels for the acre annually. The spirit distilled from E-ice 

 and molasses is known as Arrack. 



Oryza latifolia, Humboldt and Bonplaud. 



Central America. This species is said to be perennial and 

 to attain a height of eighteen feet. It deserves here trial- 

 culture, and may prove a good fodder-grass on wet land in 

 warm localities. O. perennis (Moench) seems closely allied. 



Osmitopsis asteriscoides, Cassini. 



South Africa. A camphor-scented shrub, much in use there 

 for medicinal purposes (Dr. Pappe). 



Ostrya carpinifolia, Scopoli. 



South Europe and Orient. The Hop Hornbean. A deci- 

 duous tree, 60 feet high. 



Ostrya Virginica, Willdenow. 



Leverwood-tree of North America, 40 feet high, in rich 

 woodlands. Wood singularly hard, close-grained and heavy, 

 in use for levers and other implements, for mill-cogs, wheels, 

 &c. Cattle browse on the foliage. 



Oxalis crassicaulis, Zuccarini. 



Peru. This seems one of the best of those Woodson'els, 

 which yield a tuberous edible root. Amongst others O. 

 tuberosa (Mol.) and 0. succulenta (Barn.) from Chili, as well 

 as O. carnosa (Mol.) and O. conorrhiza (Jacq.) from Paraguay, 

 might be tried for their tubers. 



Oxalis esculent a, Otto and Dietrich. 



Mexico, there with 0. tetraphylla (Cavanilles), O. Deppei 

 (Loddiges), O. violacea (Linne) and several others producing 

 tuberous starchy wholesome roots ; the first mentioned gives 

 the largest yield. As similarly useful may be mentioned 

 among many others — O. crenata (Jacquin), from Chili and O. 

 enneaphylla (Cavanilles), from the Falkland Islands and 

 Magelhaen's Straits. 



Oxytenanthera Thwaitesii, Munro. 



Ceylon, on mountains from 4000 to 6000 feet high. A 

 dwarf but handsome Bamboo, reaching only a height of 12 feet. 



Oxytropis pilosa, Candolle. (Astragalus pilosus, Linn^.) 



Europe, West Asia. This perennial plant furnishes fair 

 pasture-herbage; the numerous other species, twenty-four 

 alone enumerated as oriental by Boissier, should be tested.
