STAMENS AND GLANDULAR HAIRS OF THE MOTH MULLEIN. 



The President, in explanation of the objects exhibited by 

 him, said: "The three species of Mullein common to the North- 

 ern United States are much inclined to hybridization. The 

 specimen from which these exhibits were taken had the filaments 

 of the stamens clothed with an abundant violet-colored wool, 

 which is characteristic of F. Blattaria ; but it also had the entire 

 surface abounding with whitish glandular hairs, which is char- 

 acteristic of V. Lychnitis, L. The woolly fibres of the stamens 

 are long, attenuated, with an enlarged, pear-shaped distal 

 extremity. 



" The glandular hairs are advantageously shown on a thin trans- 

 verse section of the ovary. These hairs are so abundant that 

 they project from the cuticle of such a thin section in the manner 

 of the teeth of a cog-wheel. The hairs are comparatively short 

 and stout, and composed of three or four cells, so as to resemble 

 a turned column, or baluster, of an elegant pattern. The gland 

 at the summit of each hair is in the form of a glassy globe about 

 four times the diameter of the supporting hair ; and the globe is 

 ornamented with a beautiful closely-fluted pattern which extends 

 from the horizontal diameter to the point of support."
