Bamboo orchid (Arundina graminifolia) is a plant species in Orchidaceae, perennial terrestrial orchid, reed stems standing upright or horizontal, tubular, up to 2 m high, forming large clumps on forest slopes, agricultural land, plantations, roadsides and abandoned land.

A. graminifolia has linear leaves, grows along the stem, seated opposite, oblong lanceolate, 9-19 cm long, 1-1.5 cm wide, thick, a vein in the middle, pointed tip, amplexicaul sheath and dark green.

Clusters of flowers in slightly open terminals up to 10 buds, blooming successively at the terminals, 7-16 cm long. The flowers are 5-8 cm in diameter, reddish purple in color and white disc with purple lips. The bracts are broad triangular in shape and surround the main stalk of the flower bunch.

Plumeria rubra and Plumeria obtusa, the differences

SPECIES HEAD TO HEAD - The genus frangipani trees ( Plumeria Tourn. ex L.) has only 18 officially recorded species and two very similar species, frangipani ( Plumeria rubra L.) and white frangipani ( Plumeria obtusa L.). Both have the same habitus, flowers and fruits and are difficult to distinguish. The leaves of both species have slightly different shapes. Therefore, the leaves are very important to distinguish the two species, especially the shape of the tip. P. rubra has simple, lanceolate leaves with acute tips. P. obtusa has simple, elliptic leaves with rounded tips. By Aryo Bandoro Founder of Dlium.com . You can follow him on X: @Abandoro . Read more: Plumeria rubra Plumeria obtusa
