Nepenthes Adnata
''Nepenthes adnata'' is a tropical pitcher plant endemic to the Indonesian province of West Sumatra, where it grows at elevations of 600 to 1200 m above sea level. The specific epithet ''adnata'' is Latin for "broadly attached" and refers to the base of the lamina. Botanical history ''Nepenthes adnata'' was first collected by Willem Meijer on August 24, 1957. The holotype, ''Meijer 6941'', was collected on that date near the river Tjampo, east of Payakumbuh, Taram, West Sumatra, at an elevation of 1000 m. It is deposited at the National Herbarium of the Netherlands in Leiden.Clarke, C.M. 2001. ''Nepenthes of Sumatra and Peninsular Malaysia''. Natural History Publications (Borneo), Kota Kinabalu. The species was first described in 1986 by Mitsuru Hotta and Rusjdi Tamin based on specimens the authors collected near Harau in West Sumatra. Tamin, R. & M. Hotta 1986.

Nepenthes Of Sumatra And Peninsular Malaysia
''Nepenthes of Sumatra and Peninsular Malaysia'' is a monograph by Charles Clarke on the tropical pitcher plants of Sumatra, Peninsular Malaysia, and their minor surrounding islands. It was published in 2001 by Natural History Publications (Borneo). Clarke described it as "intermediate between an ecological monograph and a taxonomic one".Clarke, C.M. 2001. ''Nepenthes of Sumatra and Peninsular Malaysia''. Natural History Publications (Borneo), Kota Kinabalu. Background The work was conceived in late 1997Clarke, C.M. 2000. ''Proceedings of the 3rd Conference of the International Carnivorous Plant Society'': 9. and represents the culmination of 3 years of intensive research that included 15 field trips and numerous herbarium visits. The project encountered a number of difficulties and setbacks, including a "severe drought" in 1997 and political unrest in the following two years. Of the species covered in the book, Clarke observed all but three in the field. ''Nepenthes lavicola'' co ...

Peristome
Peristome (from the Greek ''peri'', meaning 'around' or 'about', and ''stoma'', 'mouth') is an anatomical feature that surrounds an opening to an organ or structure. Some plants, fungi, and shelled gastropods have peristomes. In mosses In mosses, the peristome is a specialized structure in the sporangium that allows for gradual spore discharge, instead of releasing them all at once. Most mosses produce a capsule with a lid (the operculum) which falls off when the spores inside are mature and thus ready to be dispersed. The opening thus revealed is called the ''stoma'' (meaning "mouth") and is surrounded by one or two peristomes. Each peristome is a ring of triangular "teeth" formed from the remnants of dead cells with thickened cell walls. There are usually 16 such teeth in a single peristome, separate from each other and able to both fold in to cover the stoma as well as fold back to open the stoma. This articulation of the teeth is termed arthrodontous and is found in the ...

Tendril
In botany, a tendril is a specialized stem, leaf or petiole with a threadlike shape used by climbing plants for support and attachment, as well as cellular invasion by parasitic plants such as ''Cuscuta''. There are many plants that have tendrils; including sweet peas, passionflower, grapes and Chilean glory-flower. Tendrils respond to touch and to chemical factors by curling, twining, or adhering to suitable structures or hosts. History The earliest and most comprehensive study of tendrils was Charles Darwin's monograph ''On the Movements and Habits of Climbing Plants,'' which was originally published in 1865. This work also coined the term circumnutation to describe the motion of growing stems and tendrils seeking supports. Darwin also observed the phenomenon now known as tendril perversion, in which tendrils adopt the shape of two sections of counter-twisted helices with a transition in the middle. Biology of tendrils In the garden pea, it is only the terminal leaflets ...

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. London, 4th ed 1928 Plants Botanically, pinnation is an arrangement of discr ...

Adnate
Adnate may refer to: * Adnation, in botany, the fusion of two or more whorls of a flower * Adnate, in mycology, a classification of lamellae (gills) * Conjoined twins Conjoined twins – sometimes popularly referred to as Siamese twins – are twins joined ''in utero''.

Lanceolate
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ...

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 ...
