About:

These fascinating ferns are epiphytes, typically found growing in the canopies of mature trees. They feature a fleshy, creeping to climbing stem known as a rhizome, which is adorned with large, orange-brown scales that provide a striking visual contrast against their surroundings. The fronds of these ferns exhibit a dark glossy green hue and possess a leathery texture, making them resilient in their arboreal habitat. Each frond is intricately divided, showcasing a delicate yet robust structure that aids in maximising sunlight absorption while minimising water loss. This unique adaptation not only enhances the fern’s ability to thrive in high-altitude environments but also contributes to the rich biodiversity of the ecosystems in which they reside. The presence of these ferns in the treetops adds to the complexity and beauty of the forest landscape, as they create a habitat for various other organisms and play a vital role in the ecological dynamics of their environment.
