What are the morphological characteristics of this plant?
Pteris terminalis has pinnate fronds that typically measure between 20 and 60 centimeters in length, featuring a dark green color and a distinctively textured surface. The individual pinnae are lanceolate in shape and are arranged symmetrically along a central rachis that often displays a reddish or brownish hue. The margins of the leaflets are frequently serrated or lobed, which contributes to the overall delicate appearance of the foliage. Small, kidney-shaped sori are located on the underside of the mature leaves to facilitate spore production. These morphological features allow the fern to thrive in shaded, humid environments.
What is the geographical distribution of this plant?
This plant is native to the tropical and subtropical regions of Southeast Asia, specifically spanning across countries such as Thailand, Malaysia, Indonesia, and parts of the Philippines.
