Xerorchis
''Xerorchis'' (from Greek ''xeros'', dry, and ''orchis'', testicle-shaped) is an orchid genus in the subfamily Epidendroideae, and the sole representative of tribe Xerorchideae. This is a very primitive genus consisting of terrestrial orchids. ''Xerorchis'' thrives in South America. Taxonomy It is unclear whether this genus should be classified in the lower or higher epidendroids. ''Xerorchis'' has 8 pollinium, pollinia, hence similar to the more advanced epidendroid genera of Epidendreae and Arethuseae. Yet its morphology (biology), morphology, with unthickened Plant stem, stems and persistent leaf, leaves, is that of a bambusoid grass and makes it more similar to Tropidieae or Triphoreae.

Grass
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light ...

Plant Stem
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue. The stem can also be called halm or haulm. The stem is normally divided into nodes and internodes: * The nodes hold one or more leaves, as well as buds which can grow into branches (with leaves, conifer cones, or flowers). Adventitious roots may also be produced from the nodes. * The internodes distance one node from another. The term "shoots" is often confused with "stems"; "shoots" generally refers to new fresh plant growth including both stems and other structures like leaves or flowers. In most plants stems are located above the soil surface but some plants have underground stems. Stems have four main functions which are: * Support for and the elevation of leaves, flowers, and fruits. The stems ke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Rudolf Schlechter
Friedrich Richard Rudolf Schlechter (16 October 1872 – 16 November 1925) was a German taxonomist, botanist, and author of several works on orchids. He went on botanical expeditions in Africa, Indonesia, New Guinea, South and Central America and Australia. His vast herbarium was destroyed during the bombing of Berlin in 1945. Early life Rudolf Schlechter was born on 16 October 1872 in Berlin, the third of six children. His father Hugo Schlechter was a lithographer. After finishing school at the Friedrich Wilhelm Gymnasium he started a horticulture education, first at the gardening market of Mrs. Bluth and then at the University of Berlin garden. There he worked as an assistant till the autumn of 1891. His brother was Max Schlechter (1874–1960), was a German trader and collector of natural history specimens. Career Rudolf Schlechter began his career of botanical fieldwork by leaving Europe in 1891 to journey to Africa and subsequently across Indonesia and Australia. Thr ...

Arethuseae
Arethuseae is a mid-sized tribe of orchids in the subfamily Epidendroideae. This tribe was initially categorized by John Lindley in 1840. Its largest subtribes are Arethusinae and Coelogyninae. Bletiinae was once considered a subtribe of Arethuseae, but it was moved to Epidendreae in 2005.C. Van den Berg "Artificial key to the subtribes of Epidendreae" in Pridgeon, Crib, Chase & Rasmussen, Eds.''Genera Orchidacearum Volume 4 Epidendroideae (Part one)'' p. 164. Oxford University Press, 2005 Sobraliinae has been considered a subtribe of Arethuseae, but is now recognized at the rank of tribe within the subfamily Epidendroideae. The genus ''Thunia'' has been considered to be the only genus in the subtribe Thuniinae, but is now included in the subtribe Coelogyninae.
