in Extra-Tropical Countries. 243- 



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 (Barnsaud) from Chili, as well as O. carnosa 

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

 for their tubers. 



Oxalis crenata, Jacquin. 



Peru and Bolivia; there the tubers largely consumed; they lose 

 their acidity by being exposed to the sun, becoming sweet and con- 

 taining a good deal of starch (Vilmorin). 



Oxalis Deppei, Loddiges. 



Mexico. The tubers of this Wood- Sorrel resemble small parsnips, 

 and are not at all acid. The plant undergoes regular cultivation in 

 some parts of its native country, and succeeds well in the south of 

 England (Chambers). In Prof. Meehan's Gardeners' Monthly, 

 August 1884, an Oxalis is mentioned as cultivated in California, 

 which produced as much as 150 tubers in a season, their form being 

 pear-like, from one original root. 



Oxalis esculenta, Otto and Dietrich. 



" Spurious Aracacha." Mexico, there with the preceding species 

 and O. tetraphylla (Cavanilles), 0. violacea (Linne) and several 

 others producing tuberous, starchy, wholesome roots; the first-men- 

 tioned gives the largest yield. Propagated by subdivision of the 

 root-stock. It requires a deep, rich, moist soil. In Norway it can 

 be grown to lat. 70 (Schuebeler). As similarly useful, may be 

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

 O. enneaphylla (Cavanilles) from the Falkland-Islands and Magel- 

 haen's Straits. 



)xytropis pilosa, De Candolle. (Astragalus pilosus, Linne.) 



Europe, West- Asia. This perennial plant furnishes fair pasture- 

 herbage; it is deep-rooted and content with almost absolute sand; 

 the numerous other species 24 alone enumerated as Oriental by 

 Boissier should be tested. All these plants might be classed as 

 Astragals. They as a rule are satisfied with poor soil. 



Pachyma Cocos, Fries. 



The Tuckahoe-Truffle or Indian Bread. North-America and East- 

 Asia.
