OXERA

OXYPETALUM 



plentifully in dry weather ; otherwise, if the roots are 

 allowed to become dry, they split upon the occurrence 

 of moist weather. Protect from early frosts, in October 

 or November, by a mat covering. 



About ten roots are enough for a dish. They are very 

 useful as a vegetable from early in October to the end of 

 December. An inferior kind has often been substituted 

 for it, viz. the O'xalis jacqiiinia'na ; but this is distin- 

 guished by having pink flowers. In Belgium, the leaves, 

 being gratefully acid, are used for the same purposes as 

 sorrel, and the flowers are mixed with other salad-herbs. 



As it is not a very common vegetable, it may be useful 

 to state, as an improved mode of cooking, that after 

 peeling the tubers, and cleaning out their hollow centres, 

 they must be well boiled in rich stock (gravy), skimming 

 off the fat, and then be served up hot, with a sauce 

 made of a little butter heated until brown, with a 

 spoonful of flour, and a little of the stock.

OXYCO'CCUS. Cranberry. (From oxus, acid, and 

 kokkos, a berry. Nat. ord. Cranberries [Vacciniaceae], 

 Linn. 8-Octandria, i-Monogynia.) 



Hardy, pink-flowered evergreens. Seeds, but gene- 

 rally by dividing the plants, by layering the shoots, by 

 merely placing sandy peat around them, and by cutting 

 off the points of shoots, and inserting them in sandy 

 peat, under a hand-light, in summer. Marshy, peaty 

 soil, such as a bed surrounded with water. The Cran- 

 berry, however, has been grown successfully in a bed on 

 a north border, without any water round it, and the 

 produce was good and plentiful. O. macroca'rpus pro- 

 duces the largest fruit. See AMERICAN CRANBERRY.
