Leaf Window
Leaf window, also known as epidermal window, and fenestration. is a specialized leaf structure consisting of a translucent area through which light can enter the interior surfaces of the leaf where photosynthesis can occur. The translucent structure may include epidermal tissue, and in some succulent plants it consists of several cell layers of parenchyma, which may also function as water-storage tissue. It can appear as a large continuous patch, a variegated or reticulated region, or as numerous small spots. Is found in some succulent plants native to arid climates, allowing much of the plant to remain beneath the soil surface where it is protected from desiccation by winds and heat while optimizing light absorption. Many species featuring leaf windows are native to Southern Africa. Functions The primary function of the translucent windows is to increase the absorption of radiant energy, and thereby the rate of photosynthesis. Epidermal windows are commonly situated at the apex of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perforate Leaf
Perforate leaves, sometimes called fenestrate, occur naturally in some species of plants. Holes develop as a leaf grows. The size, shape, and quantity of holes in each leaf can vary greatly depending on the species and can even vary greatly within a given species. Perforation is caused by sections of leaf ceasing cell growth or by dying during an early stage in the development of the leaf. These deformations that are created earliest in the leaf development end up looking more like slashes whereas those that develop later end up looking more like holes. This trait is found in only one species in Aponogetonaceae, Aponogeton madagascariensis (Madagascar laceleaf), and a few genera in Araceae, particularly Monstera. It is not fully known what evolutionary purpose perforation serves, but there are several possibilities. Perforation could serve the purpose of reducing the variations in growth rate, minimize chances of leaves tearing in high winds or it could help to maximize the amount ...

Cephalotus Follicularis
''Cephalotus'' ( or ; Greek: ''κεφαλή'' "head", and ''οὔς''/''ὠτός'' "ear", to describe the head of the anthers) is a genus which contains one species, ''Cephalotus follicularis'' the Albany pitcher plant, a small carnivorous pitcher plant. The pit-fall traps of the modified leaves have inspired the common names for this plant, which include 'Albany pitcher plant", "Western Australian pitcher plant", "Australian pitcher plant", or "fly-catcher plant." It is an evergreen herb that is endemic to peaty swamps in the southwestern corner of Western Australia. Description ''Cephalotus follicularis'' is a small, low growing, herbaceous species. Evergreen leaves appear from underground rhizomes, are simple with an entire leaf blade, and lie close to the ground. The insectivorous leaves are small and have the appearance of moccasins, forming the 'pitcher' of the common name. The pitchers develop a dark red colour in high light levels but stay green in shadier conditions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarracenia
''Sarracenia'' ( or ) is a genus comprising 8 to 11 species of North American pitcher plants, commonly called trumpet pitchers. The genus belongs to the family Sarraceniaceae, which also contain the closely allied genera '' Darlingtonia'' and ''Heliamphora''. ''Sarracenia'' is a genus of carnivorous plants indigenous to the eastern seaboard of the United States, Texas, the Great Lakes area and southeastern Canada, with most species occurring only in the south-east United States (only '' S. purpurea'' occurs in cold-temperate regions). The plant's leaves have evolved into a funnel or pitcher shape in order to trap insects. The plant attracts its insect prey with secretions from extrafloral nectaries on the lip of the pitcher leaves, as well as a combination of the leaves' color and scent. Slippery footing at the pitcher's rim, causes insects to fall inside, where they die and are digested by the plant with proteases and other enzymes. Description ''Sarracenia'' are herba ...

Peperomia Nivalis
''Peperomia nivalis'' is a species of plant in the genus ''Peperomia'' endemic to Peru. Its native habitat is found in the high altitude ranges of the peruvian Andes. ''P. nivalis'' is a compact erect succulent herb with fleshy stems and leaves. The thick leaves are cuneate and U-shaped in cross-section with epidermal windows on the top-side. The leaf color is bright green in the shady summer and reddish during dry sunny seasons. In addition to the basic ''P. nivalis'' four other varieties and forms are known: ''Peperomia nivalis ''f.'' diminuta'', ''Peperomia nivalis ''var.'' compacta'', ''Peperomia nivalis ''var.'' lepadiphylla'' (a.k.a. ''Peperomia pruinosifolia''), and ''Peperomia nivalis ''var.'' sanmarcensis''. They all share basic characteristics, such as the windowed leaves, but there also clear differences. For example, the variety ''P. nivalis lepadiphylla'' features trailing rather than erect stems and shorter leaves which resemble peas or lentils. Varieties of ''Pe ...

Peperomia Columella
''Peperomia columella'' is a species of plant in the family Piperaceae. The species is endemic to Peru. It grows in dry areas, often in crevices on steep cliffs or in sandy soil.Christensen-Dean, Gay A.; Moore, Randy; Development of Chlorenchyma and Window Tissues in Leaves of Peperomia columella. Annals of Botany 71:141-146 1993 It grows to about 20 cm in height, forming snake-like stems, which carry closely packed succulent bright green leaves.

Peperomia
''Peperomia'' is one of the two large genera of the family Piperaceae. It is estimated that there are at least over 1,000 species, occurring in all tropical and subtropical regions of the world. They are concentrated in northern South America and Central America, but are also found in Africa, southern Asia, and Oceania. The exact number is difficult to tell as some plants have been recorded several times with different names (c. 3,000 names have been used in publications) and new species continue to be discovered. Peperomias have adapted to many different environments and their appearance varies greatly. Some are epiphytes (growing on other plants) or lithophytes (growing on rock or in rock crevices), and many are xerophytes (drought-tolerant) either with thick succulent structures or with underground tubers (geophytes). Most species are compact perennial shrubs or vines. The genus name ''Peperomia'' was coined by Spanish botanists Ruiz López and Pavón Jiménez in 1794 aft ...

Haworthiopsis Tessellata
''Haworthiopsis tessellata'', formerly ''Haworthia tessellata'', is a species of the genus ''Haworthiopsis'' belonging to the family Asphodelaceae. It has been considered a subspecies of its close relative, ''Haworthiopsis venosa''. Etymology The genus name ''Haworthiopsis'' means "like ''Haworthia''", which honors the British botanist Adrian Hardy Haworth (1767–1833), while the species Latin epithet ''tessellata'' means "square-patterned".
