Bamboo orchid (Arundina graminifolia)

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.

Fertilized seed pods will form small powdered seeds and small plants often develop near the tips after flowering, most likely aiding propagation if allowed to reach the ground.

Six new species forming the Sumbana species group in genus Nemophora Hoffmannsegg 1798 from Indonesia

NEWS - Sumbawa longhorn ( Nemophora sumbana Kozlov, sp. nov.), Timor longhorn ( Nemophora timorella Kozlov, sp. nov.), shining shade longhorn ( Nemophora umbronitidella Kozlov, sp. nov.), Wegner longhorn ( Nemophora wegneri Kozlov, sp. nov.), long brush longhorn ( Nemophora longipeniculella Kozlov, sp. nov.), and short brush longhorn ( Nemophora brevipeniculella Kozlov, sp. nov.) from the Lesser Sunda Islands in Indonesia. The Lesser Sunda Islands consist of two parallel, linear oceanic island chains, including Bali, Lombok, Sumbawa, Flores, Sumba, Sawu, Timor, Alor, and Tanimbar. The oldest of these islands have been continuously occurring for 10–12 million years. This long period of isolation has allowed significant in situ diversification, making the Lesser Sundas home to many endemic species. This island chain may act as a two-way filter for organisms migrating between the world's two great biogeographic regions, Asia and Australia-Papua. The recognition of a striking cli...

Perlis fairy lantern (Thismia perlisensis) resembling Thismia arachnites Ridley and Thismia javanica J.J.Sm.

NEWS - Perlis fairy lantern ( Thismia perlisensis Besi & Rusea sp. nov.) was discovered during a scientific expedition in a wetland forest at the foot of a limestone hill, Perlis State Park, resembling Thismia arachnites Ridley (1905) and Thismia javanica J.J.Sm. (1910), but has a prominent reddish dome-shaped annulus. Thismia perlisensis can be easily distinguished from T. arachnites and T. javanica by its blood-red dome-shaped annulus (vs. ring-like with a rim, orange annulus), prominent trilobed stigma with bifid and subulate lobes 1.8 mm long (vs. oblong, truncated stigma), and claviform apex of inner tepal appendage (vs. subulate apex of inner tepal appendage). Stenoendemic to northern Peninsular Malaysia, Perlis State and possibly Langkawi Island. Although there have been sightings of the plant on Langkawi Island, this location is based solely on photos posted on social media. There are currently no specimens or additional information to confirm. The new species grows in...
