Mexican whorled milkweed is insect-pollinated in a manner sim- 

 ilar to that described in detail in the horsetail-milkweed discussion 

 in this handbook. The waxy, paired pollen masses (pollinia) at- 

 tached by stalks (translators) to a small, sticky body (corpuscu- 

 lum) on the stigma, become stuck to the legs of bees and other insects 

 and are thus carried from one flower to another.
