Lepidozamia
''Lepidozamia'' is a genus of two species of cycad, both endemic to Australia. They are native to rainforest climates in eastern Queensland and eastern New South Wales. They have a diploid chromosome number of 2n = 18. Etymology The name is derived from the Greek word ''lepis'' (λεπίς) meaning scale, which refers to the scale-like structure of the stem and leaf bases. Species A specimen of ''L. hopei'' is known as the tallest living cycad at 17.5 m tall. These cycads are generally unbranched, tall, and with persistent leaf bases. They are easily cultivated as ornamental plants and are relatively cold hardy; ''L. peroffskyana'' was first described by a specimen grown at St. Petersburg Saint Petersburg ( rus, links=no, Санкт-Петербург, a=Ru-Sankt Peterburg Leningrad Petrograd Piter.ogg, r=Sankt-Peterburg, p=ˈsankt pʲɪtʲɪrˈburk), formerly known as Petrograd (1914–1924) and later Leningrad (1924–1991), i ...'s botanical garden in 1857.

Lepidozamia Peroffskyana
''Lepidozamia peroffskyana'' is a palm-like cycad in the family Zamiaceae. It is endemic to eastern Australia. The species is named after Count Peroffsky (1794-1857), benefactor of the St. Petersburg Botanical Garden. Description left, Leaf detail. ''Lepidozamia peroffskyana'' is slow-growing, low maintenance, long-lived cycad that makes a good feature plant in semi-shaded positions or in a container. It grows up to seven metres tall but more usually reaches about four metres. The trunk is up to eighty centimetres in diameter and is covered by the persistent remains of leaf bases forming an interesting texture. The crown develops from numerous leaves up to three metres long, each bearing about two hundred narrow, glossy, dark green leaflets, somewhat lax, spreading and softly coriaceous. Each has seven to thirteen parallel veins which helps to distinguish this species from other members of the genus. The cylindrical cones are some of the largest of all cycad cones, rivalle ...

Cycad
Cycads are seed plants that typically have a stout and woody (ligneous) trunk with a crown of large, hard, stiff, evergreen and (usually) pinnate leaves. The species are dioecious, that is, individual plants of a species are either male or female. Cycads vary in size from having trunks only a few centimeters to several meters tall. They typically grow very slowly and live very long. Because of their superficial resemblance, they are sometimes mistaken for palms or ferns, but they are not closely related to either group. Cycads are gymnosperms (naked-seeded), meaning their unfertilized seeds are open to the air to be directly fertilized by pollination, as contrasted with angiosperms, which have enclosed seeds with more complex fertilization arrangements. Cycads have very specialized pollinators, usually a specific species of beetle. Both male and female cycads bear cones ( strobili), somewhat similar to conifer cones. Cycads have been reported to fix nitrogen in asso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wiktionary
Wiktionary ( , , rhyming with "dictionary") is a multilingual, web-based project to create a free content dictionary of terms (including words, phrases, proverbs, linguistic reconstructions, etc.) in all natural languages and in a number of artificial languages.

Chromosome
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. Chromosomes are normally visible under a light microscope only during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, each chromosome is duplicated ( S phase), and both copies are joined by a centromere, resulting either in an X-shaped structure (pictured above), if the centromere is located equatorially, or a two-arm structure, if the centromere is located distally. The joined copies are now c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
