The Mountain Dendrobium

**(Dendrobium montanum)**

Dendrobium montanum is a captivating orchid endemic to the lush tropical mountainous regions (you probably guessed it from its specific epithet - montanum!) of Java, Indonesia. Thriving at higher altitudes ranging from 1,400 to 2,000 meters, this orchid enjoys the cool, misty environments of montane forests - exactly the kind of environment that our Cloud Forest recreates! - where it grows either as an epiphyte on trees or as a lithophyte on rocky surfaces.

A member of the genus Dendrobium, this large and familiar genus encompasses over 1,500 species and is one of the largest genera within the orchid (Orchidaceae) family! Dendrobium orchids are known for their adaptability to diverse habitats, ranging from the hot seaside to cold mountain slopes, and various colours of flowers, ranging from white, pink, orange to purple and even blue! All these characteristics make this genus particularly fascinating to botanists and orchid enthusiasts alike.

The appearance of Dendrobium montanum is especially appealing, with long, slender pseudobulbs (which are thickened stems for storing nutrients and water, to help the orchid live through the dry season) and thick, fleshy leaves that are vibrantly green, serving as an attractive backdrop to bring out its fascinating flowers.

The flowers of Dendrobium montanum are delicate yet eye-catching, sometimes accented with a subtle sweet fragrance. Its single flower is small, about 4 cm in diameter, but typically appears in clusters, each containing three to seven flowers, creating a visually stunning effect. The petals and sepals vary in color, often in shades of white or pale pink. A yellow or orange patch on the center of the lip (also called "labellum") contrasts with the light colour of the petals and sepals.

N.B. A bulb is a shortened stem surrounded by thickened leaves, which is underground. A pseudobulb is a thickened stem, which is above ground. Many epiphytic orchids, which grow on tree trunks and branches, possess pseudobulbs.
