Dendrobium peguam Orchid Flower Picture

Dendrobium is a large genus of orchids. They contains about 1,200 species. The genus occurs in various habitats such as throughout much of south, east and southeast Asia, including China, Japan, India, the Philippines, Indonesia, Australia, New Guinea, Vietnam etc.

In 1799, Olof Swartz establish Dendrobium genus.

In 1981, Briegar reclassified all terete-leaved Dendrobiums from Australia and New Guinea into a new genus, Dockrillia. The Winika orchid from New Zealand was formerly D. cunninghamii, but has now been moved into a monotypic genus Winika

In 1989, Clements upgraded the D. speciosum complex into individual species;[2] similarly, the D. bigibbum complex (which contains the well-known Cooktown Orchid of Australia, D. phalaenopsis) has recently been split up. However, as an illustration of the current revisions in the taxonomy of Orchidaceae these 'splits' have now been reversed and the currently accepted species, natural nothospecies and synonyms are presented on Wikispecies Dendrobium.

  Dendrobium species are either epiphytic or lithophytic. They have adapted to a wide variety of habitats.

  Dendrobium is sympodial-type of orchids. They develop pseudobulbs, which in length from less than 1 centimetre to several metres long, looklike canes. Leaf bases form sheaths that completely envelope the stem.

  Ovate-leaves grow alternately over the whole length of the stems, Some species the leaves are bunched towards the apex of the stem. The axillary inflorescence in length from less to 1m long, and canes carry from a few to more 100 flowers. Deciduous species carry their leaves for one to two years then typically flower on leafless canes, while canes of evergreen species usually flower in the second year and can continue to flower for a number of years.

  These orchids grow quickly throughout summer, but take a rest during winter. Dormant buds erupt into shoots from the base of the pseudobulb mainly in spring, and a few species in autumn. This is then followed by rapid growth of new roots. Reproduction is usually through seed.

In report ... you can found this species in only Thailand. But at present you can found them on internet. (I'm joke!)

        Flowers of Dendrobium peguam have small size. But its beautiful.

Characteristics

   Stem Sympodial: The plant produces a series of adjacent shoots which grow to a certain size, bloom and then stop growing, to be then replaced. Sympodial orchids grow laterally rather than vertically, following the surface of their support. The growth continues by development of new leads, with their own leaves and roots, sprouting from or next to those of the previous year.

Cattleya Orchid Flower Picture

Cattleyas have been hybridized both within the genus and with related genera for more than a century, but the last several decades have seen a remarkable increase in both the quantity and quality of the hybrids within the Cattleya alliance. Among the most popular are the Brassolaeliocattleya (Blc.) and Sophrolaeliocattleya (Slc.) hybrids. The vast majority of the Blc. hybrids have recently been moved into the new nothogenus Rhyncholaeliocattleya (Rlc.); the Slc. mostly into Cattleya, with a few in Laleliocattleya (Lc.)

Type of Growing

Cattleya orchid is growing is Sympodial-type; Orchids are growing that grow sideways across the top of the pot. These orchids have a rhizome at the base usually put in horizontal, The bud at the base will begin growing anther rhizome. and then ,The rizome develops into a small plant or pseudobulb, and flower. When pseudobulbs have completely healthy, It will lose its leaves celled this pseudobulbs that "backbulb". It served store feed more years before it die.

Cattleya are epiphytes ; Growing on clinging to branches of trees. Roots orchids have thick roots covered with silver or white velamen. Which adsorb moisture and nutrients from the air such as Plalaenopsis Dendrobium etc.

Type of Roots

Cattleya orchids are semi-aerial roots : Usually found on the rocks or the trees. Roots can be absorbed many water. it smaller aerial roots. Most roots inside the pot. But may have some roots emerge outside the pot. This orchid roots not like a tight pots or wet for too long, Which getting air not enough.

Originally, the concept Cattleya included a requirement that the pollinarium contain only four pollinia. Starting some time after December, 2000, the Royal Horticultural Society (RHS) began re-organizing the generic boundaries with respect to hybrid registration. This has led to multiple senses of the term Cattleya, not only with respect to species, but also with respect to hybrids.

---------------------------------------------------------

About

Rhynchostylis differs from Vandas by the one-lobed lip. Rhynchostylis are also commonly called Foxtail Orchids because of their long thin densely packed inflorescences that get up to 37 cm with sweetly fragrant blooms. The inflorescences appear in autumn and winter. Due to the wide distribution of Rhynchostylis gigantea there is a range of different clones: flowers vary slightly in shape and colour (from white to dark red, with spotted forms).

Growing-Character

Rhynchostylis is monopodial-type; Orchids are growing always grows vertically. Bud that on apex will sprout leaves alternately, growth continues while old leaves and stem will die. Roots and leaves sprout alternately from below to upward. Bud completely healthy will sprout new plant.

Growing-Environment

Rhynchostylis orchids grow naturally in warm, moist, Shaded tropical areas. It's tolerant of a wider range of light conditions than other. Hobbyists wanting to grow them will need a warm, humid growing environment with air movement. Their unusually fragrant blooms often appear in the slightly cooler Winter months.

Despite being in the Vanda Tribe, they are very different from Vandas. It is They grow more slowly, their roots are more fragile, and almost any direct sun will harm them. However, they are typically grown with no potting mix on slat baskets or mounted just like Vandas.

Roots

Aerial roots; Most orchids grow on trees. Large Root which acts to store water to feed itself. Resistant to drought very well. If be grown in potting. Roots attaches potting for stem stable. If the orchid is completely healthy ,Root will branching away.

Rhynchostylis gigantea (Lindl.) Ridl

Rhynchostylis gigantea was discovered in Burma (Myanmar) by Wallich.

In 1833. Lindley described as Saccolabium giganteum.

In 1896 Its was transferred to Rhynchostylis by Ridley.

Today, there was pollen-cross. Until its have varietal names applied to different color and forms.

Blooming

Rhynchostylis gigantea blooms in January to February.

Distribution

Rhynchostylis widespread in Hainan, Andaman Islands, Myanmar, Thailand, Vietnam, Laos, Cambodia, Malaysia, Borneo, Philippines
