Cyperus papyrus COMMON NAME Papyrus FAMILY Cyperaceae AUTHORITY Cyperus papyrus L. FLORA CATEGORY Vascular – Exotic STRUCTURAL CLASS Sedges BRIEF DESCRIPTION Very tall (to 2.5 m) clump forming leafless reed-like plant with wide triangular stems several cm across, with many (often more than 100) drooping thread-like green flower branches at the top of each stem forming a mop-like structure. DISTRIBUTION Mostly northern North Island, usually close to habitation, but occasionally in remote sites. HABITAT Emergent in still and slow flowing water bodies. Mature culms, 30 Dec 2006, Auckland Zoo. FEATURES Photographer: Peter de Lange Erect perennial sedge to 2.5 (4) m tall with triangular stems up to 4 cm across arising from short thick woody rhizomes. Leaves reduced to papery brown basal sheaths. Inflorescence terminal subtended by 4-10 deciduous sheath-like bracts 7-15 cm x 1 cm. Inflorescence compound often with >100 filamentous branches 10-25 cm x 1 mm, often sterile. Fertile spikes are 3-5 slikes with 20-30 spikelets, each 3-20 flowered. Viable seed production not known from New Zealand. SIMILAR TAXA Distinctive tall leafless sedge with mop-like flower heads, unlikely to be mistaken for other naturalised sedges. FLOWERING Summer FLOWER COLOURS Green LIFE CYCLE Perennial. Reproduces in New Zealand probably only by asexual spread through layering (seed is occasionally produced but it is not yet known if Inflorescence and involucral bracts. In it is viable). Dispersed by deliberate planting or garden discards. However cultivation, Auckland. Dec 2006. Photographer: some occurrences are in very remote situations and are difficult to explain Peter de Lange if they had originated from garden discards.

Some Observations on the Nature of Papyrus Bonding
]. Ethnobiol. 11(2):193-202 Winter 1991 SOME OBSERVATIONS ON THE NATURE OF PAPYRUS BONDING PETER E. SCORA Moreno Valley, CA 92360 and RAINER W. SCORA Department of Botany and Plant Sciences University of California Riverside, CA 92521 ABSTRACT.-Papyrus (Cyperus papyrus, Cyperaceae) was a multi-use plant in ancient Egypt. Its main use, however, was for the production of laminated leaves which served as writing material in the Mediterranean world for almost 5000 years. Being a royal monopoly, the manufacturing process was kept secret. PI~us Secundus, who first described this process, is unclear as to the adhesive forces bonding the individual papyrus strips together. Various authors of the past century advanced their own interpretation on bonding. The present authors believe that the natural juices of the papyrus strip are sufficient to bond the individual strips into a sheet, and that any additional paste used was for the sole purpose of pasting the individual dried papyrus sheets into a scroll. RESUMEN.-EI papiro (Cyperus papyrus, Cyperaceae) fue una planta de uso multiple en el antiguo Egipto. Su uso principal era la produccion de hojas lami nadas que sirvieron como material de escritura en el mundo meditarraneo durante casi 5000 anos. Siendo un monopolio real, el proceso de manufactura se mantema en secreto. Plinius Secundus, quien describio este proceso por primera vez, no deja claro que fuerzas adhesivas mantenlan unidas las tiras individuales de papiro. Diversos autores del siglo pasado propusieron sus propias interpretaciones respecto a la adhesion. Consideramos que los jugos naturales de las tiras de papiro son suficientes para adherir las tiras individuales y formar una hoja, y que cual quier pegamento adicional se usa unicamente para unir las hojas secas individuales para formar un rollo.

Cyperaceae | Plantz Africa About:Reader?Url=
Cyperaceae | Plantz Africa about:reader?url=http://pza.sanbi.org/cyperaceae pza.sanbi.org Cyperaceae | Plantz Africa Cyperaceae Family: Cyperaceae Common names: sedges (Eng.); biesies (Afr.) Introduction A large, cosmopolitan family of mostly herbaceous plants, Cyperaceae occur primarily in moist temperate to wet tropical regions of the world; several species are of economic importance. Description Description Sedges are mostly perennial or sometimes annual herbs. Because many species have a tufted growth habit, long, thin-textured, narrow, flat leaves with a sheathing base, a jointed stem and much-branched inflorescences of tiny flowers, they are often described as graminoid, meaning grass-like. Indeed, many horticultural references include sedges under the general heading of grasses! Furthermore, many grasses and sedges do not fit the graminoid image at all, for example having leaf blades rounded in cross section or no leaf blades at all, or having compact, head-like inflorescences. So we end up with some grasses and sedges being called graminoids, and others being called simply herbs. To minimise confusion we prefer to restrict the term graminoid to true grasses (Family Poaceae), and to apply the new term cyperoid to members of the sedge family. All members of the sedge family such as the giant herb, papyrus, the few climbers (in genus Scleria ) and the Xerophyta -like Microdracoides from West tropical Africa, with a woody branching stem, can be comfortably accommodated by this term. Along with the similarities to grasses there are many features that distinguish sedges (such as usually leaves arranged in threes, and usually a solid stem that is triangular in cross section, and usually a conspicuously bracteate inflorescence), but they are not all observable with the naked eye.

Legibility Enhancement of Papyri Using Color Processing and Visual
Personalizing image enhancement for critical visual tasks: improved legibility of papyri using color processing and visual illusions Vlad Atanasiu 1, 2 and Isabelle Marthot-Santaniello 1 University of Basel 1 and University of Fribourg 2, Switzerland, [email protected], [email protected] Abstract Purpose: This article develops theoretical, algorithmic, perceptual, and interaction aspects of script legibility enhancement in the visible light spectrum for the purpose of scholarly editing of papyri texts. — Methods: Novel legibility enhancement algorithms based on color processing and visual illusions are compared to classic methods in a user experience experiment. — Results: (1) The proposed methods outperformed the comparison methods. (2) Users exhibited a broad behavioral spec- trum, under the influence of factors such as personality and social conditioning, tasks and application domains, expertise level and image quality, and affordances of software, hardware, and interfaces. No single enhancement method satisfied all factor configurations. Therefore, it is suggested to offer users a broad choice of methods to facilitate personalization, contextualization, and complementarity. (3) A distinction is made between casual and critical vision on the basis of signal ambiguity and error consequences. The criteria of a paradigm for enhancing images for critical applications comprise: in- terpreting images skeptically; approaching enhancement as a system problem; considering all image structures as potential information; and making

Iconic Flora of Heritage Significance in India
Indian Journal of History of Science, 51.2.2 (2016) 312-342 DOI: 10.16943/ijhs/2016/v51i2.2/48445 Iconic Flora of Heritage Significance in India H Y Mohan Ram* (Received 08 February 2016 ; revised 16 May 2016) Abstract Indian subcontinent is rich in flora for its variable geo-climatic conditions. It is not easy to select some plant species as iconic. However, a short list of plants has been prepared which Indians have valued for their well-being, culture and esteem. The banyan (Ficus benghalensis) is the National Tree of India and tops the list. Beginning as an individual sapling, it can produce an enormous forest with pillar-like prop roots. The Bodhi tree or peepul (Ficus religiosa) occurs in India and some neighbouring countries and is venerated by the Hindus, Buddhists and Jains. Gautama Buddha attained enlightenment under the peepal tree at Bodh Gaya in Bihar. Emperor Ashoka’s daughter Sanghamitra, a Buddhist nun, took a branch of this famous tree and planted it in Anuradhapura in Sri Lanka in 288 BC. People worship it as ‘Jaya Sri Maha Bodhi’. Neem (Azhadirachta indica) a most useful tree, has leaves with bitter taste. Probably a native of Burma it is cultivated abundantly in India. Neem is a source of azhadirachtin, an anti-feedant botanical pesticide, chew sticks for brushing teeth, a non-edible oil, firewood and fodder. Sheesham (Dalbergia sissoo) is the source of an exquisite wood, used for carving, and supports artisans. Nepalese use it for decorative windows with frames. Tamarind (Tamarindus indica) is a tree indigenous to tropical Africa and must have come to India a long time ago.

In Ancient Egypt, the Stems of This Plant
Cyperus papyrus ‘Crown of Pharaoh’ • Use: An exotic-looking accent with bold vertical lines. Pendulous leaves sit like umbrellas atop strong upright stems. A fast growing plant that prefers moist growing conditions. This ornamental grass combines drama, grace and humor and makes a spectacular container garden plant. The plant can be planted in pots, along the waters edge of a pond, or even in a pond. Tolerates heat! • Exposure/Soil: Full– part sun. The root ball can be submerged but it isn’t nec- essary. If the plant is put into a pot I would suggest plugging the hole or holes in the bottom of the pot to keep as much water as possible in the pot. The crown of the plant should never be covered in water and in fact both of these varieties can thrive in water as shallow as a few inches. The purpose is to keep the bulk of the soil or root mass wet. • Growth: Fast grower and can reach heights of 4-6’ tall and 3-4’ wide. In ancient Egypt, the stems of this • Hardiness: Zone 8a- 10; Tender Perennial, Not hardy enough to survive win- ters with freezing temperatures below 20 so would need protection. It is a very plant (considered by some au- fast grower and will quickly grow to impressive size when replanted in the thorities to be the bulrush of the spring.
