Minnieroot (Ruellia tuberosa)

Kencana ungu or pletesan or popping pod or minnieroot (Ruellia tuberosa) is a species of plant in the Acanthaceae, an upright herb, up to 2 meters high and has many branches. The leaves are oval, with a pointed base, blunt tip, thin, flat surface, green, flat edges and pinnate veins.

R. tuberosa has leaves up to 13 cm long, 7 cm wide and stalks up to 4 cm long. Trumpet-shaped flowers, 4-5 cm in diameter and up to 6 cm long. The thin crown is purple or blue, five strands and fused downwards to form a tube.

The fruit is tubular with a pointed tip and 2-3 cm long. Young fruit is green, old fruit is brown. If the ripe fruit is exposed to water it will burst, detach and be thrown from the stalk. The seeds are round, flat and brown. Minnieroot uses taproots and tubers.

This plant contains active chemical compounds including alkaloids, triterpenoids, flavonoids, phenolics, saponins, coumarin and quinone dyes. Roots contains apigenin and luteolin. Seed oil contains myristic, capril and lauric acid.

Traditional treatment uses R. tuberosa as an antidiabetic, antipyretic, analgesic, anti-hypertensive, anti-inflammatory and antioxidant. The leaves are ground into paste and used to treat wounds, itching, insect bites, venereal disease, wounds, tumors and rheumatic complaints.

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...
