Kanchanaburi - Wild Pink Orchids

Orchids are one of the most beautiful flowers in the world. They are treasured for their showy blossoms that are often quite large and brightly colored.

The orchid have some characteristics that make them unique among the other floral plants:
- The most important characteristic is irregular or zygomorphic flowers. The perianth is usually clearly divided into an upper and a lower half
- Orchids have undivided, and in most cases, rather narrow leaves. Leaves mostly range from linear to lanceolate in shape.
- A clearly visible feature is the column or gynostemium in the centre of the flower which contains both the style with its sticky receptive surface and the pollen. The pollen is derived from a single stamen, in very few (non-African) orchids there are two or three.
- Most orchid flowers twist through 180 just before they open. This movement which is termed resupination is necessary as the lip is originally developed on the upper side - after the resupination it is positioned on the lower side which is much more advantageous for successful pollination
- Unlike most other plants the pollen grains of orchids stick together and form masses called pollinia
- Orchids have a symbiotic relationship with fungi that live in their roots, called mycorrhiza
