EDITORS COMMENTS
This print showcases the intricate beauty of a fern leaf like never before. Taken using a scanning electron microscope (SEM), this coloured micrograph captures the underside of the leaf, revealing its hidden secrets. The focal point of this image is the sori, which are groups of sporangia that appear in striking brown hues. These sporangia play a crucial role in reproduction as they contain spores, the reproductive units unique to ferns. Adding an element of elegance to this composition is the indusium, an umbrella-shaped covering that protects and encloses these precious sporangia. Its delicate pink shade contrasts beautifully with the rich browns surrounding it. With a magnification level of x4 when printed at 10 centimetres high, every detail becomes apparent upon closer inspection. This photograph not only highlights nature's remarkable intricacy but also serves as a testament to scientific advancements in imaging technology. Perfect for enthusiasts and researchers alike, this print offers an opportunity to explore botany from a fresh perspective. Delve into the fascinating world beneath our feet and appreciate how even something as seemingly simple as a fern leaf can hold such complexity and wonder within its structure.
