93. Glume (from the Latin (/luma, a husk) is 

 seen in the calyx of grasses, and plants of that 

 family. It is known when separated from the 

 ripened seed of oats, barley, etc., as husk or 

 chaff. Those long thread-like appendages 

 called the beard of wheat and barley are parts of the 

 calyx.

95. Perianth, when applied to 

 a distinct calyx, means those cup- 

 like calyces in whicli the corolla 



may properly be said to be placed. The long 

 tubular calyx of the pink and the graceful urn- 

 shaped calyx of the rose are examples. 



96. Spatha, or sheath. This 

 very common among the bulbous-root 

 fixmilies, as in the narcissus and daffodil.

 early stage of bloom. In others they are 

 beautifully colored, and remain, consti-
