Pyrorchis
''Pyrorchis'', commonly known as beak orchids, is a genus of flowering plants in the orchid family, Orchidaceae and is endemic to Australia. It contains two species which were previously included in the genus ''Lyperanthus'', also known as beak orchids. Both species have fleshy, oval leaves and form colonies which flower profusely after bushfires. Description Orchids in the genus ''Pyrorchis'' are terrestrial, perennial, deciduous, sympodial herbs with a few inconspicuous, fine roots and an oval-shaped tuber lacking a protective sheath. Replacement tubers are formed on the end of long, thin root-like stolons. There are between one and three broad, fleshy, egg-shaped to heart-shaped leaves at the base of the plant. The leaves are long, wide and bright green, sometimes with black markings. There are up to eight resupinate flowers on a stalk high. The stalk is often surrounded by two or three loose, leaf-like bracts up to long. The dorsal sepal is lance-shaped, about long a ...

Pyrorchis Nigricans
''Pyrorchis nigricans'', commonly known as red beaks, is a species of orchid endemic to Australia and is found in all Australian states except Queensland and the Northern Territory. It has a single large, oval leaf and up to eight relatively large red and white flowers. It usually only flowers after hot fires. Description ''Pyrorchis nigricans'' is a terrestrial, perennial, deciduous, herb with an underground tuber and a single dark green leaf with red markings. The leaf is more or less oval in shape and in diameter and lies flat on the ground. Between two and eight flowers are arranged on a thick, fleshy flowering spike high. The flowers are reddish-purple and white, about long and wide with a large bract at the base. The dorsal sepal is light coloured with reddish stripes, broad lance-shaped and long with its edges turned inwards. The lateral sepals and petals are linear in shape, about the same size as the dorsal sepal but more spreading. The labellum is gently curved n ...

Lyperanthus
''Lyperanthus'', commonly known as beak orchids, is a genus of flowering plants from the orchid Family (biology), family, Orchidaceae, that is Endemism, endemic to Australia. There are two species, one in Western Australia and the other in four eastern Australian states, distinguished by their single long, narrow, leathery leaf and dull coloured flowers which have prominent short Labellum (botany), calli on their Labellum (botany), labellum. Both form loose colonies which reproduce asexually from their tubers, and sexually using their flowers. Description Orchids in the genus ''Lyperanthus'' are terrestrial, Perennial plant, perennial, deciduous, sympodial herbs usually with a few inconspicuous, fine roots and an oval-shaped, tuber lacking a protective Tunica (biology), sheath. Each year, new tubers develop on the ends of long, root-like stolons. There is a single, erect, leathery, stiff, linear to lance-shaped leaf, long, wide with tiny pimple-like Gland (botany), glands on th ...

Stolon
In biology, stolons (from Latin '' stolō'', genitive ''stolōnis'' – "branch"), also known as runners, are horizontal connections between organisms. They may be part of the organism, or of its skeleton; typically, animal stolons are external skeletons. In botany In botany, stolons are stems which grow at the soil surface or just below ground that form adventitious roots at the nodes, and new plants from the buds. Stolons are often called runners. Rhizomes, in contrast, are root-like stems that may either grow horizontally at the soil surface or in other orientations underground. Thus, not all horizontal stems are called stolons. Plants with stolons are called stoloniferous. A stolon is a plant propagation strategy and the complex of individuals formed by a mother plant and all its clones produced from stolons form a single genetic individual, a genet. Morphology Stolons may or may not have long internodes. The leaves along the stolon are usually very small, but in a few ...

Undertaker Orchid 2
A funeral director, also known as an undertaker (British English) or mortician (American English), is a professional involved in the business of funeral rites. These tasks often entail the embalming and burial or cremation of the dead, as well as the arrangements for the funeral ceremony (although not the directing and conducting of the funeral itself unless clergy are not present). Funeral directors may at times be asked to perform tasks such as dressing (in garments usually suitable for daily wear), casketing (placing the corpse in the coffin), and cossetting (applying any sort of cosmetic or substance to the best viewable areas of the corpse for the purpose of enhancing its appearance). A funeral director may work at a funeral home or be an independent employee. Etymology The term mortician is derived from the Roman word ''mort-'' (“death”) + ''-ician''. In 1895, the trade magazine ''The Embalmers' Monthly'' put out a call for a new name for the profession in the U ...

Capsule (botany)
In botany a capsule is a type of simple, dry, though rarely fleshy dehiscent fruit produced by many species of angiosperms (flowering plants). Origins and structure The capsule (Latin: ''capsula'', small box) is derived from a compound (multicarpeled) ovary. A capsule is a structure composed of two or more carpels. In (flowering plants), the term locule (or cell) is used to refer to a chamber within the fruit. Depending on the number of locules in the ovary, fruit can be classified as uni-locular (unilocular), bi-locular, tri-locular or multi-locular. The number of locules present in a gynoecium may be equal to or less than the number of carpels. The locules contain the ovules or seeds and are separated by septa. Dehiscence In most cases the capsule is dehiscent, i.e. at maturity, it splits apart (dehisces) to release the seeds within. A few capsules are indehiscent, for example those of ''Adansonia digitata'', ''Alphitonia'', and '' Merciera''. Capsules are often classifie ...

Dehiscence (botany)
Dehiscence is the splitting of a mature plant structure along a built-in line of weakness to release its contents. This is common among fruits, anthers and sporangia. Sometimes this involves the complete detachment of a part; structures that open in this way are said to be dehiscent. Structures that do not open in this way are called indehiscent, and rely on other mechanisms such as decay or predation to release the contents. A similar process to dehiscence occurs in some flower buds (e.g., ''Platycodon'', ''Fuchsia''), but this is rarely referred to as dehiscence unless wikt:circumscissile, circumscissile dehiscence is involved; anthesis is the usual term for the opening of flowers. Dehiscence may or may not involve the loss of a structure through the process of abscission. The lost structures are said to be wikt:caducous, caducous. Association with crop breeding Manipulation of dehiscence can improve crop yield since a Trait (biological), trait that causes seed dispersal i ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Labellum (botany)
In botany, the labellum (or lip) is the part of the flower of an orchid or '' Canna'', or other less-known genera, that serves to attract insects, which pollinate the flower, and acts as a landing platform for them. ''Labellum'' (plural: ''labella'') is the Latin diminutive of ''labrum'', meaning lip. The labellum is a modified petal and can be distinguished from the other petals and from the sepals by its large size and its often irregular shape. It is not unusual for the other two petals of an orchid flower to look like the sepals, so that the labellum stands out as distinct. Bailey, L. H. ''Gentes Herbarum: Canna x orchiodes''. (Ithaca), 1 (3): 120 (1923); Khoshoo, T. N. & Guha, I. ''Origin and Evolution of Cultivated Cannas.'' Vikas Publishing House. In orchids, the labellum is the modified median petal that sits opposite from the fertile anther and usually highly modified from the other perianth segments. It is often united with the column and can be hinged or movable, fac ...

Column (botany)
The column, or technically the gynostemium, is a reproductive structure that can be found in several plant families: Aristolochiaceae, Orchidaceae, and Stylidiaceae. It is derived from the fusion of both male and female parts (stamens and pistil) into a single organ. The top part of the column is formed by the anther, which is covered by an anther cap. This means that the ''style'' and ''stigma'' of the pistil, with the filaments and one or more anthers, are all united. Orchidaceae The stigma sits at the apex of the column in the front but is pointing downwards after resupination (the rotation by 180 degrees before unfolding of the flower). This stigma has the form of a small bowl, the clinandrium, a viscous surface embedding the (generally) single anther. On top of it all is the anther cap. Sometimes there is a small extension or little beak to the median stigma lobe, called rostellum. Column wings may project laterally from the stigma. The column foot is formed by the atta ...

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...
