Fern
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns. Ferns first ...

Korea National Arboretum
Korea National Arboretum () is an over-500-year-old arboretum located in Pocheon city of Gyeonggi Province of South Korea. It is widely known as "Gwangneung Forest ()" by the public. It is designated as UNESCO World Network of Biosphere Reserves, World Network of Biosphere Reserve and the country's 11th Natural monuments of South Korea, natural monument. Its history can be traced back to Joseon Dynasty. The planting of large forests started during the reign of Sejo of Joseon. He and Queen Jeonghui designated the area for a tomb which later named ''Gwangneung.'' Their tomb is one of Royal Tombs of the Joseon Dynasty, a UNESCO World Heritage Site. Following the construction of the tomb, it and its surrounding areas were designated as royal forest and kept under strict protection which lasted throughout post-Joseon history. The area was devastated during the Korean war. From 1983 to 1987, the central government went under project to develop the area as an arboretum with a forest museum ...

Stipe (botany)
In botany, a stipe is a stalk that supports some other structure. The precise meaning is different depending on which taxonomic group is being described. file:Helicteres-Yucatán-Flowers.jpg, The long stipe of a '' Helicteres'' flower. file:Helicteres-Yucatán-Fruits.jpg, remains as each flower forms a fruit. In the case of ferns, the stipe is only the petiole from the rootstock to the beginning of the leaf tissue, or lamina. The continuation of the structure within the lamina is then termed a rachis. In flowering plants, the term is often used in reference to a stalk that sometimes supports a flower's ovary. In orchids, the stipe or caudicle is the stalk-like support of the pollinia. It is a non-viscid band or strap connecting the pollinia with the viscidium (the viscid part of the rostellum or beak). A stipe is also a structure found in organisms that are studied by botanists but that are no longer classified as plants. It may be the stem-like part of the thallus of a mus ...
