otherwise, when rain falls abundantly, the sudden accession of 

 water to the roots occasions their splitting. The plants should be 

 allowed to grow as long as there is no danger from frost ; but pre- 

 viously to this occurring, they should either be taken up or pro- 

 tected. If protected from frost, by frames, or otherwise, the roots 

 will continue to increase in size till November. When taken up, 

 the roots should be divested of the numerous bulbs formed on their 

 crowns, and then stored up for use in a cool dry place, but secure 

 from frost. A similar situation will be proper for the bulbs ; or 

 they may be kept in dry sand till the season of planting. 



Mr. Cockburn, Gardener to the Earl of Mansfield, at Caen 

 Wood, Hampstead, grows this plant in perfection with no parti- 

 cular preparation of soil; merely planting the bulbs in shallow 

 drills, a foot apart, in borders dug and manured as for other 

 kitchen-garden crops. He also plants it by the sides of walks in 

 the woods, as an ornamental plant. 



We have in our gardens another Oxalis, apparently the O. Jac- 

 quiniana, which also produces tap-roots like those of O. Deppei ; 

 but they are much smaller, and inferior in quality. That species is 

 readily known by its flowers being very small and of a pale lilac 

 colour.
