ENCYCLOPEDIA OF PLANTS

Microsorum pteropus (microsorum a wing, or Thai fern)

Polypodiaceae (Mnogonozhkovye) family.
Spread. Widely distributed in tropical regions of Asia.
Amphibians, polymorphic fern with creeping, densely covered with scaly rhizome. Petiole about half a wing narrow, scaly. Leaves lanceolate first, simple, petiole short or 1 - 2 (5) lateral lobes, which are almost totally free; Central share of longer lateral length of 30 cm, a width of 5.5 cm; lateral lobes up to 21 x 3.5 cm, acute or rounded, often with a wavy edge, from olive to dark green. Central vein scaly.
Sori without film (induziya), individual, sometimes fused together randomly on the bottom side of the sheet; most nearly circular, then approximately 2 mm, rarely elongated.
Slow growing, but not sophisticated in content and popular fern. It grows in soft or hard water, in well or moderately illuminated aquariums. Optimum growth at an average intensity of light in soft to medium-hard water, and with good circulation in the weakly acid pH range. Temperature 20 - 28 degrees C. In the aquarium, the rhizome is best to put on a stone, bark, driftwood, etc., so that the roots can be fixed to them. This way you can well decorate the side and back walls of the aquarium. Transplantation is not recommended because the rhizomes in the aquarium ground badly accepted. When the culture of the ground rhizome, on the contrary, are developing well in the loose soil. Suitable for landscaping and freshwater aquariums palyudariumov. Vegetative reproduction by dividing the rhizomes of plants and subsidiaries, which are formed on leaves and roots. It is also possible generative reproduction spores. Cluster of spores detected on surface crop plants (sometimes also underwater) on the underside of leaves. Ripe, like brown powder spores can sow to a wet soil. Cultivation is not difficult, but it requires time and patience.
Thai fern grows not only in the mountains and forests in natural habitats, rivers and rocky creeks, where it is sometimes covered with water, but also on the plain, on the rocky soil and on the roots of the trees standing in water.
