23O ORCHIDS. 



Foliage light green ; flowers pale yellow and green, 

 produced several together on a spike ; the petals are 

 prolonged into two tails, which hang from each flower, 

 about twenty inches long. Blooms in March, April, and 

 May. 



This is one of the most extraordinary of Orchids. 

 When the flowers expand, the petals are only about an 

 inch long, but in a few days they extend to two feet in 

 length, so that they trail on the ground, unless the plant 

 is placed on a stand. The sepals and petals are yellow- 

 ish brown ; the lip reddish brown. 



Care must be taken not to over-water this plant, as it 

 makes but few roots ; it does not require much heat. It 

 blooms from the last year's growth in early spring. 



Called also Selenipedium caudatum.
