Stamens and Glandular Hairs of the Moth Mullein. J. 1. Za-

It is stated that the glandular hairs are advantageously shown 
on a thin transverse section of the ovary; they are comparatively 
short and stout, and composed of three or four cells, The gland 
is a globe about four times the diameter of the hair, and is or- 
namented with a beautiful closely-fluted pattern below the hori- 
zontal diameter. The specimen examined appears to have been 
a hybrid between Verbascum Blattaria and V. Lychnitis.
