Compound flowers, bell-like petals and a crown shaped like a collection of white or yellow needles. The fruit is box-shaped, has 5 ribs and has black hairs which then turn into small and light seeds.

This species grows in open places exposed to full sunlight or slightly protected such as cliffs, edges of waterways and abandoned land. It grows well in areas with lots of rain at an elevation of 50-1650 meters.

This plant contains alpha-lactuserol, β-lactoserol, mannitol, inositol, silica, potassium, flavonoids, tarak-sasterol, volatiles (decanal, eicosane, phytol, dokozan), aliphatic hydrocarbon, benzoic acid. Widely used to treat gout, kidney stones, urinary stones, gallstones, coughs, asthma, bronchitis, swelling and sedatives.

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...
