Idiospermum
''Idiospermum'' is a genus containing a single species of tree, ''Idiospermum australiense'', found in Australian tropical rainforests. The species represents one of the earliest known lineages of flowering plants, dating back as far as 120 million years. It is found today only in the Daintree and Wet Tropics rainforests region of north-eastern Queensland. It is endemic to a very few locations in north-eastern Queensland (e.g. in Daintree National Park), in the very wet lowland parts of the forest, in groups of 10–100 trees together (rather than scattered individuals). Common names include ribbonwood and idiot fruit. Description Ribbonwood trees grow naturally in their wet tropical rainforest habitats as evergreens up to about tall and about in diameter at breast height (DBH). The simple leaves grow singly, in pairs or in whorls of 3–4, each one measuring about long and wide. The flowers measure in diameter, with all floral organs spirally arranged. The tepals are initi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Daintree Rainforest
The Daintree Rainforest is a region on the northeast coast of Queensland, Australia, north of Mossman, Queensland, Mossman and Cairns. At around , the Daintree is a part of the largest continuous area of tropical rainforest on the Australia (continent), Australian continent. The Daintree Rainforest is a part of the Wet Tropics of Queensland Rainforest, that spans across the Cairns Region. The Wet Tropics Rainforest (that the Daintree is a part of) is the oldest continually surviving tropical rainforest in the world. Along the coastline north of the Daintree River, tropical forest grows right down to the edge of the sea. In 2009 as part of the Q150 celebrations, the Daintree Rainforest was announced as one of the Q150 Icons of Queensland for its role as a "natural attraction". History and description About Daintree Rainforest The Daintree Rainforest was once a vast forest that covered the entire Australian continent. It is a rare survival of 120 million years of climate change ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ludwig Diels
Dr. Friedrich Ludwig Emil Diels (24 September 1874 – 30 November 1945) was a German botanist. Diels was born in Hamburg, the son of the classical scholar Hermann Alexander Diels. From 1900 to 1902 he traveled together with Ernst Georg Pritzel through South Africa, Java, Australia and New Zealand. Shortly before the First World War he travelled New Guinea and in the 1930s in Ecuador. Especially his collections of plants from Australia and Ecuador, which contained numerous holotypes, enriched the knowledge of the concerning floras. His monography on the Droseraceae from 1906 is still a standard. The majority of his collections were stored at the botanical garden in Berlin-Dahlem, whose vicedirector he had been since 1913, becoming its director in 1921 until 1945. His collections were destroyed there during an air raid in 1943. He died in Berlin on 30 November 1945. Honours Several genus of plants have been named after him including; ''Dielsantha'' (from ''Campanulaceae' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diprotodon
''Diprotodon'' (Ancient Greek: "two protruding front teeth") is an extinct genus of marsupial from the Pleistocene of Australia, containing one species, ''D. optatum''. The earliest finds date to 1.77 million to 780,000 years ago, but most specimens are dated to after 110,000 years ago. Its massive fossils were first unearthed in 1830 in Wellington Caves, New South Wales, before any serious scientists were active on the continent, and were variably guessed to belong to rhinos, elephants, hippos, or dugongs. ''Diprotodon'', formally described by Sir Richard Owen in 1838, was the first named Australian fossil creature, and set Owen on a path to becoming the foremost authority of his time on other marsupials and Australian megafauna so enigmatic to European science. ''Diprotodon'' is the largest known marsupial to have ever lived, far dwarfing its closest living relatives, wombats and koalas. It grew as large as at the shoulders, over from head to tail, and possibly almost in w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Musky Rat-kangaroo
The musky rat-kangaroo (''Hypsiprymnodon moschatus'') is a small marsupial found only in the rainforests of northeastern Australia. First described in the later 19th century, the only other species are known from fossil specimens. They are similar in appearance to potoroos and bettongs, but are not as closely related. Their omnivorous diet is known to include materials such as fruit and fungi, as well as small animals such as insects and other invertebrates. The local Aboriginal name for the species is durrgim yuri''.'' Taxonomy The description of this species, assigned to a new genus ''Hypsiprymnodon'', was published in 1876 by Edward Pierson Ramsay, a curator at the Australian Museum. The syntypes are part of the museum's collection, mounted specimens of a male and female collected at Rockingham Bay, Queensland. Ramsay's specimens were obtained during European settlement of northeastern Australia on an expedition toward the Herbert River. A description of the species was ...

Staminodes
In botany, a staminode is an often rudimentary, sterile or abortive stamen, which means that it does not produce pollen.Jackson, Benjamin, Daydon; ''A Glossary of Botanic Terms with their Derivation and Accent''; Published by Gerald Duckworth & Co. London, 4th ed 1928 Staminodes are frequently inconspicuous and stamen-like, usually occurring at the inner whorl of the flower, but are also sometimes long enough to protrude from the corolla. Sometimes, the staminodes are modified to produce nectar, as in the Witch Hazel ''( Hamamelis)''.jin lu mei shu. Hamamelis Linnaeus, Sp. Pl. 1: 124. 1753. Flora of China 9: 32. 2003 Staminodes can be a critical characteristic for differentiating between species, for instance in the orchid genus ''Paphiopedilum'', and among the penstemons. In the case of Cannas, the petals are inconsequential and the staminodes are refined into eye-catching petal-like replacements. A spectacular example of staminode is given by ''Couroupita guianensis'', a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dicotyledon
The dicotyledons, also known as dicots (or, more rarely, dicotyls), are one of the two groups into which all the flowering plants (angiosperms) were formerly divided. The name refers to one of the typical characteristics of the group: namely, that the seed has two embryonic leaves or cotyledons. There are around 200,000 species within this group. The other group of flowering plants were called monocotyledons (or monocots), typically each having one cotyledon. Historically, these two groups formed the two divisions of the flowering plants. Largely from the 1990s onwards, molecular phylogenetic research confirmed what had already been suspected: that dicotyledons are not a group made up of all the descendants of a common ancestor (i.e., they are not a monophyletic group). Rather, a number of lineages, such as the magnoliids and groups now collectively known as the basal angiosperms, diverged earlier than the monocots did; in other words, monocots evolved from within the dicot ...

Monocotyledon
Monocotyledons (), commonly referred to as monocots, (Lilianae ''sensu'' Chase & Reveal) are grass and grass-like flowering plants (angiosperms), the seeds of which typically contain only one embryonic leaf, or cotyledon. They constitute one of the major groups into which the flowering plants have traditionally been divided; the rest of the flowering plants have two cotyledons and are classified as dicotyledons, or dicots. Monocotyledons have almost always been recognized as a group, but with various taxonomic ranks and under several different names. The APG III system of 2009 recognises a clade called "monocots" but does not assign it to a taxonomic rank. The monocotyledons include about 60,000 species, about a quarter of all angiosperms. The largest family in this group (and in the flowering plants as a whole) by number of species are the orchids (family Orchidaceae), with more than 20,000 species. About half as many species belong to the true grasses ( Poaceae), which are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cotyledon
A cotyledon (; ; ; , gen. (), ) is a significant part of the embryo within the seed of a plant, and is defined as "the embryonic leaf in seed-bearing plants, one or more of which are the first to appear from a germinating seed." The number of cotyledons present is one characteristic used by botanists to classify the flowering plants (angiosperms). Species with one cotyledon are called monocotyledonous ("monocots"). Plants with two embryonic leaves are termed dicotyledonous ("dicots"). In the case of dicot seedlings whose cotyledons are photosynthetic, the cotyledons are functionally similar to leaves. However, true leaves and cotyledons are developmentally distinct. Cotyledons are formed during embryogenesis, along with the root and shoot meristems, and are therefore present in the seed prior to germination. True leaves, however, are formed post-embryonically (i.e. after germination) from the shoot apical meristem, which is responsible for generating subsequent aerial por ...
