 TYD.^A— DISPLAY. 



The class to which this belongs furnishes many of our most 

 striking ornamental plants for the stove and greenhouse, which 

 are most useful, from many of them flowering at seasons of the 

 year when the summer plants are past their best. At that 

 time how grateful are the brilliant or soft blossoms of Achi- 

 menes, Gloxinia, Gresneria, Plectopoma, Tydsea, and other allied 

 genera ; and how admirably they are suited for introduction 

 into living rooms, or for table decoration, for, being bulbous 

 plants, they do not suffer the permanent injury that many do 

 when exposed to the trying ordeal of gas and dust. 



For the Tyda^a which we now figui'e we are indebted to the 

 estidalishment of Mr. William Bull. It is valuable for its 

 winter blooming qualities, coming fully into bloom at a season 

 of the year when flowers are especially sought after. The 

 individual flowers are large and well formed ; the tube is of a 

 bright carmine colour, densely covered with short crimson 

 hairs ; the lobes, which are very broad and ample, are pink, 

 beautifully reticulated with rich crimson ; the mouth is a rich 

 violet carmine colour ; and the throat white, blotched with 

 deep orange. 



The culture of the Tydsea does not differ from that of 

 Achimenes; they should be started in a good heat, then potted 

 off" into larger pots, and removed to an intermediate house. 

 They can also be grown in shallow pans, or in baskets ; they 

 delight in heat, moisture, and shade, when growing ; but when 

 in bloom, may be gradually ti-ansferred to a cooler house.
