tanist. Their roots are, generally, bulbs, articulated, jointed, 

 or granulated in a manner peculiar to this genus and one 

 or two others. They grow well in sandy loam, and require 

 only very small pots ; great care must be taken not to water 

 them after they have done flowering. They are readily in- 

 creased by small bulbs or offsets, and many of the species 

 produce seeds. All those species which flower between 

 June and November may be grown in the open air, in the 

 following manner. The bulbs being obtained, plant in beds 

 in the course of the month of April, protect with mats dur- 

 ing severe weather, and every night till the end of May ; 

 then all covering may be removed for the season. After 

 this, one kind will come into flower after another till Octo- 

 ber or November ; and as each sort finishes flowering, and 

 the leaves begin to fade, take it up and place the bulbs 

 (each sort by itself) in small pots of dry sand, and set them 

 in a dry loft, not colder than a green-house, during winter, 

 till wanted for planting in the open air next spring. Txias, 

 Gladioluses, and various other green-house bulbs, may be 

 treated in the same manner with complete success. (See
