56 ORCHID FAMILY 



a dense cluster of roots, and opens a wonderful white 

 flower whose lip is extended in two narrow segments, and 

 whose slender spur is nearly half a foot in length. lonopsis 

 utricularioides, which is reported by Mr. W. M. Buswell 

 as growing on citrus trees, bears a panicle of small white 

 to rose-colored flowers, veined with deeper color on the 

 broad lip, and resembling somewhat the blossoms of 

 bladderworts. The thick, linear leaves are two to six inches 



long. 



In several of our epiphytic orchids the base of the 

 plant is swollen and forms a pseudobulb, which is thought 

 to serve as a reservoir of moisture. The aerial roots of 

 many are provided with a corky white covering which ab- 

 sorbs moisture from the air, and also serves to protect the 

 active cells in the interior.
