Peucedanum Cervaria
''Peucedanum cervaria'' is a herbaceous plant in the genus ''Peucedanum'' belonging to the carrot family Apiaceae. Description ''Peucedanum cervaria'' reaches on average in height, with a maximum of . The stems are cylindrical, glabrous and erect. They are more or less branched and the leaves are slightly blue-green and two to three times pinnate, pinnatifid. The large umbels have 9 to 30 rays bearing small white flowers. The flowering period extends from July through September in their native habitat. This plant has its overwintering buds situated just below the soil surface (Raunkiær plant life-form#Hemicryptophytes, hemicryptophyte) and an almost leafless stalk growing directly from the ground (Glossary of botanical terms, scapose). The fruits are oval, about 4 to 6 mm long and 3 to 4 mm wide, with narrow marginal ridges. Distribution This plant is a sub-Mediterranean species widespread in southern and central Europe, from Spain, Italy and the Balkan Peninsula up ...

Herbaceous
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the ''Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, the parts of ...

Apiaceae
Apiaceae or Umbelliferae is a family of mostly aromatic flowering plants named after the type genus ''Apium'' and commonly known as the celery, carrot or parsley family, or simply as umbellifers. It is the 16th-largest family of flowering plants, with more than 3,700 species in 434 generaStevens, P.F. (2001 onwards)Angiosperm Phylogeny Website Version 9, June 2008. including such well-known and economically important plants as ajwain, angelica, anise, asafoetida, caraway, carrot, celery, chervil, coriander, cumin, dill, fennel, lovage, cow parsley, parsley, parsnip and sea holly, as well as silphium, a plant whose identity is unclear and which may be extinct. The family Apiaceae includes a significant number of phototoxic species, such as giant hogweed, and a smaller number of highly poisonous species, such as poison hemlock, water hemlock, spotted cowbane, fool's parsley, and various species of water dropwort.

Pinnate
Pinnation (also called pennation) is the arrangement of feather-like or multi-divided features arising from both sides of a common axis. Pinnation occurs in biological morphology, in crystals, such as some forms of ice or metal crystals, and in patterns of erosion or stream beds. The term derives from the Latin word ''pinna'' meaning "feather", "wing", or "fin". A similar concept is "pectination," which is a comb-like arrangement of parts (arising from one side of an axis only). Pinnation is commonly referred to in contrast to "palmation," in which the parts or structures radiate out from a common point. The terms "pinnation" and "pennation" are cognate, and although they are sometimes used distinctly, there is no consistent difference in the meaning or usage of the two words.Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co.

Raunkiær Plant Life-form
The Raunkiær system is a system for categorizing plants using life-form categories, devised by Danish botanist Christen C. Raunkiær and later extended by various authors. History It was first proposed in a talk to the ''Danish Botanical Society'' in 1904 as can be inferred from the printed discussion of that talk, but not the talk itself, nor its title. The journal, Botanisk Tidsskrift, published brief comments on the talk by M.P. Porsild, with replies by Raunkiær. A fuller account appeared in French the following year. Raunkiær elaborated further on the system and published this in Danish in 1907.Ch. 2 in Raunkiær (1934): The life-forms of plants and their bearings on geography, p. 2-104. The original note and the 1907 paper were much later translated to English and published with Raunkiær's collected works.Ch. 1 in Raunkiær (1934): Biological types with reference to the adaption of plants to survive the unfavourable season, p. 1. Modernization Raunkiær's life-form sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
