Stellate leaf hairs
False colour scanning electron micrograph of stellate leaf hairs on the surface of the hoary mullein Verbascum pulverulentum. This is a perennial herbaceous wild plant, which grows in France. Germany & England. The stellate leaf hairs are typical of alpine plants exposed to strong light & drying winds. They serve a biological function for the leaf by limiting transpiration & reducing surface temperature. The density of the hairs lends the leaf a white appearance. It is held that the hairs were scrapped from the leaves, rolled like cotton & used as wicks in the lamps of the neolithic flint miners at Grimes Graves, Norfolk. Magnification: X 37 at 35mm size. Original is BW print B745/079

EDITORS COMMENTS
This print showcases the intricate beauty of stellate leaf hairs found on the surface of the hoary mullein, a perennial herbaceous wild plant that thrives in France, Germany, and England. These unique leaf hairs are commonly seen in alpine plants that endure intense sunlight and drying winds. However, they play a vital biological role for the leaves by limiting transpiration and reducing surface temperature. The density of these delicate hairs gives the leaf a striking white appearance. Interestingly, it is believed that ancient neolithic flint miners at Grimes Graves in Norfolk utilized these very same hairs as wicks for their lamps. The hypothesis suggests that these remarkable structures were carefully scraped from the leaves, rolled like cotton, and used to provide illumination deep within the mines. Captured under scanning electron microscopy at 37 times magnification (35mm size), this false-color image reveals every intricate detail of these stellate leaf hairs. The original black-and-white print B745/079 perfectly highlights their fascinating structure. This mesmerizing photograph not only celebrates nature's ingenuity but also offers a glimpse into how even seemingly insignificant elements can have practical applications throughout history.
