156 THE TRITONIA. 



There are about twenty-five species of tritonia, of which 

 those most commonly grown are 



T. crocata. This species is commonly known in green- 

 houses as orange ixia, and is one of the most floriferous of 

 Cape bulbs. It requires only to be potted, syringed for 

 red spider, and regularly watered ; and, in April, is sure to 

 give a profusion of its rich orange-flowers. 



It propagates rapidly by offsets and by seed, which comes 

 true. 



T. crispa. The flowers are pale bluish color, and resem- 

 ble a babiana. The plant does not flower until very late 

 in the spring. 



T. rosea. A handsome but delicate species with rosy 

 flowers, having a deep pink tube. 



T. longiflora. The flowers are dirty white, and, as the 

 name indicates, have very long tubes : there are varieties 

 with straw-color and yellow flowers. The species grows 

 and flowers freely, and is, with the varieties, one of 

 the most satisfactory of the family for greenhouse cul- 

 ture. 



T. fucata. A very showy plant with yellow and red 

 flowers of a peculiar form. The species multiplies freely, 

 but is difficult to flower.
