Dipteris conjugata is a species of fern. It has a rhizome, and 2-3 tall stems with mid green or dark green fronds, which have several divisions to toothed lobes. It is grows in clearings, mountain ridges and in forest margins, from tropical and temperate Asia, northern Queensland in Australia and some islands in the Pacific Ocean. It has limited native medicinal uses. Description It has a creeping rhizome, covered with black shiny hairs, or reddish brown hairlike scales. The hairs are 4 to 5 mm long and 0.2 mm in diam. The hairs are more like bristles on the older sections of the rhizomes. It is up to 1 cm or more in diameter. It has Stipes (or stalks) that are normally between tall, but stipes up to have also been found. They have hair-like scales at base, which then becomes smooth and glabrous. They are stramineous (straw coloured) to brown. The leaf stems appear at regular intervals along the rhizome. and branch three or four times, (these rhizomes are usually terrestrial, but can also climb trees) with 1 metre wide fronds, or lamina (leaf blades). The mid green, or dark green fronds, but paler or glaucous underneath. are between long and wide. They are divided to the base into two spreading fan-shaped halves, which are further divided more than halfway into 4 or more unequal lobes, these lobes are again less deeply lobed once or more times. The ultimate lobes taper to a narrow apex with the edges deeply or coarsely toothed. The main veins are dichotomously branched several times. The veins on the fronds are also dichotomously-branched with 2–4 main veins entering each of the lobes. The juvenile fronds are tomentose (with a layer of downy hairs). On the lower surface of the fronds, are numerous, small sori (spore producers), they are irregularly scattered and of irregular size and shape. They do not have indusia (umbrella-like covers) and have paraphyses (filament-like support structures) which are club-shaped. Biochemistry The leaves contain 2 ent-kauranoid hydroxy acids. Taxonomy In Fijian, it is known as koukoutangane, or 'aivuiniveli'. In Thailand it is called bua chaek and bua cek in Singapore, It is written as 双扇蕨 or 破傘蕨, in Chinese script, and known as shuang shan jue in Pinyin in China. The Latin specific epithet conjugata refers to the leaf having one pair of leaflets. It was described by Caspar Georg Carl Reinwardt
