Tilia Amurensis
''Tilia amurensis'', commonly known as the Amur lime or Amur linden, is a species of ''Tilia'' native to eastern Asia. It differs from the better-known ''Tilia cordata'' in having somewhat smaller leaves, bracts and cymes. It is an important timber tree in Russia, China and Korea, and is occasionally planted as a street tree in cities with colder climates. Description ''Tilia amurensis'' is a medium sized shade tree which can grow up to tall. The appearance is quite similar to '' Tilia japonica'' besides the difference in size of leaves, bracts and a shorter cyme. ''Tilia amurensis'' is a hermaphrodite, which means it contains both female and male organs, and is mainly pollinated by insects. Habitat ''Tilia amurensis'' prefers a medium moisture level and fertile, well drained, loamy soil. It has the ability to adapt to several different ranges of soil conditions as well as a good tolerance for urban conditions. It is often found in mixed forests across China, North Korea, So ...

Tilia
''Tilia'' is a genus of about 30 species of trees or bushes, native throughout most of the temperateness, temperate Northern Hemisphere. The tree is known as linden for the European species, and basswood for North American species. In Great Britain and Ireland they are commonly called lime trees, although they are not related to the citrus Lime (fruit), lime. The genus occurs in Europe and eastern North America, but the greatest species diversity is found in Asia. Under the Cronquist system, Cronquist classification system, this genus was placed in the family Tiliaceae, but genetic research summarised by the Angiosperm Phylogeny Group has resulted in the incorporation of this genus, and of most of the previous family, into the Malvaceae. ''Tilia'' is the only known ectomycorrhizal genus in the family Malvaceae. Studies of ectomycorrhizal relations of ''Tilia'' species indicate a wide range of fungal symbionts and a preference toward Ascomycota fungal partners. Description ''T ...

Tilia Cordata
''Tilia cordata'', the small-leaved lime or small-leaved linden, is a species of tree in the family Malvaceae, native to much of Europe. Other common names include little-leaf or littleleaf linden, or traditionally in South East England, pry or pry tree. Its range extends from Great Britain, Britain through mainland Europe to the Caucasus and western Asia. In the south of its range it is restricted to high elevations. Description ''Tilia cordata'' is a deciduous tree growing to tall, diameter 1/3 to 1/2 the height, with a trunk up to diameter. The largest known trunk circumference was a specimen in Närke, Sweden, that measured circumference at chest height. There are lime trees in Germany that are said to be over 1000 years old. The bark is smooth and grayish when young, firm with vertical ridges and horizontal fissures when older. The crown is rounded in a formal oval shape to pyramidal. Branching is upright and increases in density with age. The leaf, leaves are alternately ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bract
In botany, a bract is a modified or specialized leaf, associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves in size, color, shape or texture. They also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate or ebracteolate. Variants Some bracts are brightly coloured which aid in the attraction of pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of '' Euphorbia pulcherrima'' (poinsettia) and '' Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and palea (upper bract), while each spikelet (group of florets) has a further pair o ...

Cymes
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis ( peduncle) and by the timing of its flowering (determinate and indeterminate). Morphologically, an inflorescence is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. General characteristics Inflorescences are described by many different characteristics including how the flowers are arranged on the peduncle, the blooming order of the flowers ...

Tilia Japonica
''Tilia japonica'', the Japanese lime or Japanese linden, is a species of ''Tilia'' native to eastern China and Japan, preferring to grow in mountains up to 2000m. It superficially resembles the better-known ''Tilia cordata'', the small-leaved lime, and was originally described as ''Tilia cordata'' var. ''japonica''. It differs from ''T. cordata'' in having 164 chromosomes instead of 82, and by some subtle differences in leaf and flower morphology. ''T. japonica'' inflorescences consistently have 5 staminodes, which is a reliable trait distinguishing it from ''T. cordata'' and '' T. amurensis''. Recent studies indicate ''T.japonica'' to play an important role in maintaining the ectomycorrhizal networks in local forests it grows in Japan. Cultivation and uses ''Tilia japonica'' is grown as an ornamental tree. Its 'Ernest Wilson' cultivar has gained the Royal Horticultural Society's Award of Garden Merit. Its wood was used for furniture, and due to its straight grain is still occas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indumentum
In biology, an indumentum (Latin, literally: "garment") is a covering of trichomes (fine "hairs") on a plant or of bristles (rarely scales) of an insect. Plants The indumentum on plants can have a wide variety of functions, including as anchorage in climbing plants (e.g., '' Galium aparine''), in transpiration control, in water absorption ('' Tillandsia''), the reflection of solar radiation, increasing water-repellency (e.g., in the aquatic fern '' Salvinia''), in protection against insect predation, and in the trapping of insects ('' Drosera'', '' Nepenthes'', '' Stylosanthes''). Plant indumentum types include *hirsute *lanate *pilose *pubescent *scabrous *scurfy *stellate * tomentose *villous Insects The use of an indumentum on insects can be pollen-related as on bees, sensory like whiskers, or for other uses including adhesion and poison.

Glabrous
Glabrousness () is the technical term for a lack of hair, down, setae, trichomes, or other such covering. A glabrous surface may be a natural characteristic of all or part of a plant or animal, or be due to loss because of a physical condition, such as alopecia universalis in humans, which causes hair to fall out or not regrow. In botany Glabrousness or otherwise, of leaves, stems, and fruit is a feature commonly mentioned in plant keys; in botany and mycology, a ''glabrous'' morphological feature is one that is smooth and may be glossy. It has no bristles or hair-like structures such as trichomes. In anything like the zoological sense, no plants or fungi have hair or wool, although some structures may resemble such materials. The term "glabrous" strictly applies only to features that lack trichomes at all times. When an organ bears trichomes at first, but loses them with age, the term used is ''glabrescent''. In the model plant ''Arabidopsis thaliana'', trichome formation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of The Russian Far East
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) wa ...

Trees Of China
In botany, a tree is a perennial plant with an elongated Plant stem, stem, or trunk (botany), trunk, usually supporting Branch, branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only Bark (botany), woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller Arecaceae, palms, Cyatheales, tree ferns, Musa (genus), bananas, and bamboos. Trees are not a Monophyletic group, monophyletic taxonomic group but consist of a wide variety of plant species that Convergent evolution, have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
