Description

Casuarina junghuhniana is an evergreen tree growing to 15–35 m (50–115 ft) tall. [4] The foliage consists of slender, much-branched green to grey-green twigs 0.8–1 mm (0.032–0.039 in) diameter, bearing minute scale-leaves in whorls of 9–11. It is dioecious and The flowers are produced in small catkin-like inflorescences. The fruit is an oval woody structure, superficially resembling a conifer cone made up of numerous carpels each containing a single seed with a small wing 4–5 mm (0.16–0.2 in) long. [5] Unlike Casuarina equisetifolia , Mountain Ru (C. junghuhniana) has a narrower canopy, small and neat branches. It has a straight and knotless trunk. [4] [6]

Like some other species of the genus Casuarina , C. junghuhniana is an actinorhizal plant able to fix atmospheric nitrogen. In contrast to species of the plant family Fabaceae (e.g., beans, alfalfa, Acacia), Casuarina harbours a symbiosis with a Frankia actinomycete. [7]

Taxonomy

There are two subspecies: [8]

Distribution and habitat
