alternate year they may be cleared from the old soil, 

 and put in smaller pots with the crown barely covered. 

 When the flowers fade, the pedicles twist up like a 

 screw, inclosing the germen in the centre, lying close 

 to the ground until the seeds ripen, from which plants 

 can be grown, and will flower the third year. 



Lachendlia, a genus of about forty species of bulbs, 

 all natives of the Cape of Good Hope, and grow re- 

 markably well in our collections. The most common 

 is L. tricolor. L. quadricolor, and its varieties, are all 

 fine; the colours yellow, scarlet, orange, and green,

 are on a stem from a half to one foot high, and much in 

 the character of a hyacinth. The end of the month is 

 about the time of planting. Five inch pots are large 

 enough, and they must get very little water till they be-

 and like all other bulbs of that country, they do exceed- 

 ingly well in our collections, in which there are only 

 comparatively a few species, not exceeding twelve. O. 

 rubella, branching, of a vermilion colour ; O. mafginata, 

 white ; O. elongdta, striped ; and O. amcena, are those 

 that require potting this month. The first of Septem-

This genus of plants is so varied in the construction 

 of its roots, that the same treatment will not do for all. 

 The root is commonly bulbous, and these will keep a 

 few weeks or months out of the soil, according to their 

 size. Several are only thick and fleshy : these ought
