About : .
Dendrobium bigibbum is one of a group of Dendrobium species that are collectively known as the Cooktown orchid. It forms small to medium sized slender clumps on trees and rocks. Clumps consist of a number of erect, cylindrical stems which are slightly swollen in the middle with rounded bases. The stems are green or purplish and can reach a height of 1.2m and a width of 15mm. When the stems are young they are covered in papery bracts (very small scale-like leaves). There are 3-12 leaves on the upper part of the stem. Leaves are narrowly ovate, 5-15cm long by 0.5-3.5cm wide and dark green but often with purplish margins or heavily suffused with purple. The arching flower stems can reach 40cm and bear 2-20 flowers.
The flowers are pansy-like and usually lilac purple, although may sometimes be white, bluish or pinkish. The flowers are 3-5cm wide and the petals generally curve backwards. The petal that projects forwards is called the labellum and has three lobes. The two outer lobes curve upwards and overlap to form a column. The middle lobe is projected forward, curves downward and has a spot with prominent ridges covered by dense white hairs.
