Wild Yellow Lily. The Lilium Canadensis, L., is com- 

 mon in our northern swamps. The flowers are pendulous, 

 the perianth consists of six parts, yellowish-orange With 

 brown spots. The nectary occurs in the form of a groove in 

 the middle of each division of the perianth. The six stamens 

 have their linear anthers eitrorsely attached near the middle 

 finally becoming versatile. The style is elongated and some- 

 what club shaped; the stigma three lobed. It is pollinated 

 by Hymenoptera. Mr. Weed records Megachik, but I have 

 observed Trochilus. The Lilium Mortagon is pollinated by 

 Sphlngidae.
