Information: - The Orchidaceae are a diverse and widespread family of flowering plants, with blooms that are often colourful and often fragrant, commonly known as the orchid family. - In plant systematics Epidendroideae is a subfamily of the orchid family, Orchidaceae. Epidendroideae is larger than all the other orchid subfamilies together, comprising more than 15,000 species in 576 genera. Most Epidendroid orchids are tropical epiphytes, typically with pseudobulbs. There are, however, some terrestrials such as "Epipactis" and even a few myco-heterotrophs, which are parasitic upon mycorrhizal fungi. - Pabstiella is a small orchid genus belonging to the subfamily Epidendroideae . They occur in Central and Tropical America . While the '' Checklist of Monocotyledons '' of Kew Botanical Gardens ( 2005 ) considers Pabstiella as an accepted name , it is considered a synonym of Pleurothallis by the Vascular plant families and genera ( R.K. Brummitt , 1992 ) . The synonym Anthereon Pridgeon & M. W. Chase is a nom . illeg . because it includes the type of the earlier accepted name Pabstiella - An epiphyte is a plant that grows harmlessly upon another plant (such as a tree) and derives its moisture and nutrients from the air, rain, and sometimes from debris accumulating around it. Epiphytes differ from parasites in that epiphytes grow on other plants for physical support and do not necessarily negatively affect the host. An epiphytic organism that is not a plant is called an epibiont. Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the tropics (e.g., many ferns, cacti, orchids, and bromeliads). Epiphyte species make good houseplants due to their minimal water and soil requirements. Epiphytes provide a rich and diverse habitat for other organisms including animals, fungi, bacteria, and myxomycetes. - The pseudobulb is a storage organ found in many epiphytic and terrestrial sympodial orchids. It is derived from a thickening of the part of a stem between leaf nodes and may be composed of just one internode or several, termed heteroblastic and homoblastic respectively. All leaves and inflorescences usually arise from this structure. Pseudobulbs formed from a single internode produce the leaves and inflorescence from the top, while those that are formed from several internodes can possess leaves along its length. The modified sheath leaves that appear at the base of a pseudobulb and often enfold all or part of it are usually dry and papery, though in some orchids the sheaths bear leaf blades and the leaves at the pseudobulb's apex are reduced to scales. - Epipactis, or Helleborine, is a genus of terrestrial orchids consisting of approximately 70 species. This genus is abbreviated as Epcts in horticultural trade. What is the relationship between 'pabstiella' and 'orchidaceae'?
