344 Select Plants for Industrial Culture and 



Oryzopsis panicoides, Bentham. (Piptochcetium panicoictes, E. Desvaux.) 



Extra-tropical South- America. This with some congeners affords 

 good pasturage in Chili and the La Plata-States [Hieronymus]. 



Osmanthus fragrans, Loureiro. 



China and Japan. The flowers of this bush serve for oil-distilla- 

 tion like those of the Jasmine. The scent of one plant will perfume 

 a whole conservatory [G-. W. Johnson]. 



Osmitopsis asteriscoides, Cassini. 



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

 medicinal purposes [Dr. Pappe]. 



Ostrya carpinifolia, Scopoli. 



" The Hop-Hornbeam/' South-Europe and Orient. A deciduous 

 tree, reaching 60 feet in height. Uses much like those of the fol- 

 lowing. 



Ostrya Virginica, Willdenow. 



" Lever-wood " Tree of Eastern States of North- America, also 

 Mexico. Occasionally called Iron-wood ; to 40 feet high, in rich 

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

 Cattle browse on the foliage. The growth of the tree is very slow. 



Osyris compressa, A. de Candolle. (Colpoon compressum, Bergins.) 



South- Africa. One of the most valuable tans for finer leathers is 

 provided there by the leaves and young twigs of this shrub or small 

 tree. The bloom obtained from this tan is much like that imparted 

 by Sumach. 



Owenia venosa, F. v. Mueller. 



Queensland ; called locally Sour-Plum. A tree, approaching finally 

 40 feet in height, furnishing a wood of great strength. O. acidula, 

 F. v. M., the " Rancouran," is a handsome tree, 50 feet high, with 

 close-grained, nicely-marked wood. Culture might improve the 

 fruits. 



Oxalis crassicaulis, Zuccarini. 



Peru. This seems one of the best of those Wood-Sorrels, which 

 yield a tuberous edible root. Amongst others, O. tuberosa (Molina) 

 and O. succulenta (Barneaud) from Chili, as well as O. carnosa 

 (Molina) and O. conorrhiza (Jacquin) from Paraguay, might be tried 

 for their tubers.
