In the first two tribes the pollen is waxy. In the first tribe the 

 pollinia are either free from each other, or the separate pairs cohere 

 slightly by viscid threads. In the second tribe the pollinia are arranged 

 in cohering pairs on a stalk which terminates in a gland. In the 

 third and fourth tribes the pollen is granular and powdery. In the 

 former the pollinia are distinct, in the latter they are produced into 

 short tails which are attached to a gland.
