Acampe rigida, also known as banana orchid, is a large epiphyte of the orchid family. The stem is stout, nearly erect, and up to 1 m long. The leaves are two columns, long banded, nearly fleshy, and the stem is cradled at the base. The inflorescence is axillary or foliar, nearly erect, 7 cm to 30 cm long, often unbranched, and has many flowers. The flower bracts are fleshy and broadly triangular in shape. The flowers are yellow with purple-brown stripes, are not very developed, and have an aroma. The sepals and petals are nearly upright. The petals are narrowly inverted ovate with blunt apexes. The lip flap is white, thick fleshy, 3 lobes, the lateral lobes are perpendicular to the middle lobes, nearly square, the inner mask is purple-brown longitudinal stripes, the middle lobes are nearly upright, and the inner and dorsal bases have a few purplish-brown transverse stripes. The capsule is nearly erect, cylindrical or long spindle-shaped, and about 6 cm long. The flowering period is from August to September and the fruiting period is from October to November. Multi-flowered crisp orchid, also known as banana orchid, the flowers are yellow with purple-brown stripes and aromatic. The lateral lobes of the multiflorous orchid are perpendicular to the middle lobes and are nearly square, with purple-brown longitudinal stripes on the inside. In the high-value orchid plant circle, the multi-flowered crunch orchid is unremarkable. Its Latin genus name Acampe is derived from the Greek word akampas, meaning inelastic, referring to flowers that are small, brittle, and not easily bent. The crisp orchid flowers are brittle and easy to break, and the small yellow flowers are missed if they are not careful. The crisp orchid flowers are brittle and easy to break, and the small yellow flowers are missed if they are not careful. Although the multi-flowered crunch orchid growing in the tropics has a faint fragrance and can attract insects, it cannot complete pollination; However, it is the first known "rain medium" plant to rely on rain to pollinate: with the help of raindrops, the medicine cap bounces off, and then the pollen ball bounces upwards, landing into the stigma nest, and finally completing the self-pollination. The multi-flowered brittle orchid is the first known "rain medium" plant that relies on rainwater pollination.
