Ebony Fern
Plants of the Polypodaceae family belong to the Phylum Pteridophyta, Class Lestozoa, and Order Pteridophylla. There are 1,162 species in 89 genera in total. They are perennial emergent plants or heavy water plants, ranging from 15 to 25 cm in height. The rhizome is continuous, while the leaves are often simple or trident-shaped, and spores for reproduction are densely grown on the leaf spines. Generally speaking, this plant grows in understory streams in low-elevation mountains, or on trees and rocks. The leaves are thick, opaque, with ribs, scales and hairs. The leaves are simple, finger-shaped or pinnately compound. The sporangia are piled up on the underside of the leaves and are round, linear or evenly dispersed, without a covering membrane.
1. Three-pronged Iron Crown
Ferns, emergent aquatic plants. The single word Trident means the military trident of Poseidon, the god of the sea in Greek legend, and its shape is quite similar to the leaves of this aquatic plant. Like the common iron crown, the trifurcated iron crown also has prominent rhizomes and leaves. There are dark brown irregular roots under the strip rhizome. The leaves are green, and there are sporangia on the bottom of the mature leaves. Aquatic plants prefer old water and find it difficult to adapt to new water. They are most afraid of sudden changes in water quality. When the water quality is unstable, the spores on the back of the leaves are easy to germinate and grow young plants, which not only affects the beauty but also affects the growth of the mother. You may wish to plant another plant when the young plant grows to 5 centimeters, or tie it to a heavy tree or rock. The three-pronged iron crown grows slowly and is not resistant to high temperatures. If the water temperature exceeds 28°C, it is prone to "water fern disease", so it is best to breed at low temperatures.
Two, Sabah Iron Crown
Sabah Iron Crown
Fern, emergent aquatic plant, native to Sabah, Malaysia. What distinguishes it from the common iron crown is that the top of its leaves is rounder, and the leaves are completely oval-shaped. The plant is relatively thin and has obvious roots, stems and leaves. Water grass and water grass have the same shape, with black or brown adventitious roots growing under the strip-like rhizomes, and long oval leaves growing on them. There are tortoise-shell-like textures on the leaves, and brown bract sacs are spread on the bottom of the mature leaves. The plant body is green. Aquatic plants prefer old water and find it difficult to adapt to new water, so the amount of water changes should not be too frequent. When the spores on the back of the leaves germinate and young plants grow more than 5 cm, it is advisable to divide them out, otherwise they will affect the growth of the mother plant. Sabah Iron Crown is suitable for cultivation tied to heavy wood, and can also be planted in a coarse sandy bed. It can survive under the conditions of low light, low nutrition and no carbon dioxide supply.
3. Timika star fern
Timika star fern
Timika Star Fern is native to Timika in Papua Province in eastern Indonesia. It is a fern and an emergent aquatic plant. It mostly grows in humid conditions, but it has certain tolerance. The appearance of the drought-resistant plant is somewhat similar to that of the observation plant Pothos, but not like the Iron Crown. It has strong roots, slender stems and abundant leaves. The leaves of waterweed are green and shiny, mostly heart-shaped or narrowly heart-shaped, with no cracks along the entire edge. There are scattered tortoiseshell-like reticulate patterns on the surface of the leaves. When planted in water, it is best suited to being tied to heavy wood. The nutritional requirements are not high, so weakly acidic soft water is preferred. It grows slowly and can be grown without carbon dioxide, but it cannot withstand high temperatures.
4. Philippine Iron Crown
Philippine Iron Crown
Fern, emergent aquatic plant, native to Panay Island in the Philippines. Similar to the common Iron Crown The distinguishing feature is that its leaves are narrower and can withstand various extreme environments. This aquatic plant is mostly distributed in river estuary areas, so the plant has obvious roots, stems and leaves, and is tall.10-30 cm. The aquatic grass has the same shape as the aquatic grass. There are black or brown indeterminate roots under the striped rhizome, and long lanceolate leaves on the top. The veins have a tortoise shell-like pattern and the mature leaves are spreading at the bottom. The bracts are brown. The plant body is green. The grass in the water prefers old water and is difficult to adapt to new water, so the amount of water should not be changed too much when the spores on the back of the leaves germinate and the young plants grow to more than 5 cm. Divide them out, otherwise the growth of the mother plant will be affected. Philippine Iron Crown is suitable for cultivation on heavy wood, and can also be cultivated in a coarse sandy bed. p style="text-indent:2em;">5. Orange Iron Crown
Orange Iron Crown
Orange Iron Crown is a fern The plant is an emergent aquatic plant, modified from the red iron crown produced in Thailand, Indonesia and Papua New Guinea. Its shape is similar to that of ordinary iron crown, with obvious roots, stems and leaves that are similar to those of water plants. The rhizome is strip-shaped, with black or brown roots growing underneath, and long lanceolate leaves with veins like tortoise shells. The leaves are still green above the water, with brown bracts growing on them. A little orange will appear at the top. The base of the leaves grown in water is light yellow-green, the middle of the leaves is mostly yellow, and the top is orange-red. When planted in water, it is most resistant to sudden changes in water quality. It likes old water and is difficult to adapt to new water. , so the amount of water should not be changed too much when the spores germinate on the back of the leaves.When the young plants grow more than 5 cm, it is advisable to divide them out, otherwise they will affect the growth of the mother plant. The golden iron crown is suitable for planting on heavy wood, and can also be planted on a coarse sand bed with good water permeability. If you want it to develop color, a sufficient amount of carbon dioxide must be added, and the lighting must be appropriately enhanced.
