Araucaria Bidwillii
''Araucaria bidwillii'', commonly known as the bunya pine and sometimes referred to as the false monkey puzzle tree, is a large evergreen coniferous tree in the plant family Araucariaceae. It is found naturally in south-east Queensland Australia and two small disjunct populations in north eastern Queensland's World Heritage listed Wet Tropics. There are many old planted specimens in New South Wales, and around the Perth, Western Australia metropolitan area. They can grow up to . The tallest presently living is one in Bunya Mountains National Park, Queensland which was reported by Robert Van Pelt in January 2003 to be in height. The bunya pine is the last surviving species of the Section ''Bunya'' of the genus ''Araucaria''. This section was diverse and widespread during the Mesozoic with some species having cone morphology similar to ''A. bidwillii'', which appeared during the Jurassic. Fossils of Section ''Bunya'' are found in South America and Europe. The scientific name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dracaena Reflexa
''Dracaena reflexa'' (commonly called song of India or song of Jamaica) is a tree native to Mozambique, Madagascar, Mauritius, and other nearby islands of the Indian Ocean. It is widely grown as an ornamental plant and houseplant, valued for its richly coloured, evergreen leaves, and thick, irregular stems. Description While it may reach a height of 4–5 m, rarely 6 m in ideal, protected locations, ''D. reflexa'' is usually much smaller, especially when grown as a houseplant. It is slow-growing and upright in habit, tending to an oval shape with an open crown. The lanceolate leaves are simple, spirally arranged, 5–20 cm long and 1.5–5 cm broad at the base, with a parallel venation and entire margin; they grow in tight whorls and are a uniform dark green. The flowers are small, clustered, usually white and extremely fragrant, appearing in mid winter. Neither the flowers nor the fruit are especially showy. ''D. reflexa'' var. ''angustifolia'' (syn. ''D. marginata'') differs i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dracaena Fragrans
''Dracaena fragrans'' (cornstalk dracaena), is a flowering plant species that is native throughout tropical Africa, from Sudan south to Mozambique, west to Côte d'Ivoire and southwest to Angola, growing in upland regions at altitude.JSTOR Plant Science''Dracaena fragrans''/ref> It is also known as striped dracaena, compact dracaena, and corn plant. Description ''Dracaena fragrans'' is a slow growing shrub, usually multistemmed at the base, mature specimens reaching or more tall with a narrow crown of usually slender erect branches. Stems may reach up to diameter on old plants; in forest habitats they may become horizontal with erect side branches. Young plants have a single unbranched stem with a rosette of leaves until the growing tip flowers or is damaged, after which it branches, producing two or more new stems; thereafter, branching increases with subsequent flowering episodes.Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening'' 2: 96. Macmillan . The leaves are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asparagaceae
Asparagaceae, known as the asparagus family, is a family of flowering plants, placed in the order Asparagales of the monocots. The family name is based on the edible garden asparagus, ''Asparagus officinalis''. Those who live in the temperate climates may be surprised to learn that this family includes both common garden plants as well as common houseplants. The garden plants include asparagus, yucca, bluebell, and hosta, and the houseplants include snake plant, corn cane, spider plant and plumosus fern. Taxonomy In earlier classification systems, the species involved were often treated as belonging to the family Liliaceae. The APG II system of 2003 allowed two options as to the circumscription of the family: either Asparagaceae ''sensu lato'' ("in the wider sense") combining seven previously recognized families, or Asparagaceae ''sensu stricto'' ("in the strict sense") consisting of very few genera (notably ''Asparagus'', also ''Hemiphylacus''), but nevertheless totalling ...

Monocotyledons
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 ec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anthophyta
The anthophytes are a grouping of plant taxa bearing flower-like reproductive structures. They were formerly thought to be a clade comprising plants bearing flower-like structures. The group contained the angiosperms - the extant flowering plants, such as roses and grasses - as well as the Gnetales and the extinct Bennettitales. Detailed morphological and molecular studies have shown that the group is not actually monophyletic, with proposed floral homologies of the gnetophytes and the angiosperms having evolved in parallel. This makes it easier to reconcile molecular clock data that suggests that the angiosperms diverged from the gymnosperms around 320-300 mya. Some more recent studies have used the word anthophyte to describe a group which includes the angiosperms and a variety of fossils ( glossopterids, ''Pentoxylon'', Bennettitales, and ''Caytonia ''Caytonia'' is an extinct genus of seed ferns.

Pinus Patula
''Pinus patula'', commonly known as patula pine, spreading-leaved pine, or Mexican weeping pine, and in Spanish as ''pino patula'' or ''pino llorón'', (''patula'' Latin = “spreading”) is a tree native to the highlands of Mexico. It grows from 24° to 18° North latitude and above sea level. The tree grows up to tall. It cannot withstand long periods of temperatures as low as , but resists occasional brief dips below . It is moderately drought-tolerant, and in this respect is superior to ''Pinus taeda''. The average annual rainfall in its native habitat is from 750 to 2000 mm. This happens mostly in summer, but in a little area of the State of Veracruz on the Sierra Madre Oriental its habitat is rainy the year round. It is planted at high altitudes in Ecuador (3500 m), Bolivia, Colombia (3300m), Kenya, Tanzania, Angola, Zimbabwe, Papua New Guinea, and Hawaii (3000 m). In Hawaii it is replacing the native alpine grassland. At lower altitudes than its origin country it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinus Caribaea
The Caribbean pine (''Pinus caribaea'') is a hard pine species native to Central America and the northern West Indies (in Cuba, the Bahamas, and the Turks and Caicos Islands). It belongs to subsection '' Australes'' in subgenus ''Pinus''. It inhabits tropical and subtropical coniferous forests such as Bahamian pineyards, in both lowland savannas and montane forests. Taxonomy As of 2013, the species has three accepted varieties: *''Pinus caribaea'' var. ''caribaea'' – ''pino macho'', Caribbean pine, Nicaragua pine, pitch pine (Pinar del Río Province and Isla de la Juventud in western Cuba) *''Pinus caribaea'' var. ''bahamensis'' (Grisebach) W.H.Barrett & Golfari – Bahamas pine, Caicos pine, Caribbean pine (The Bahamas, Turks and Caicos Islands) *''Pinus caribaea'' var.

Pinaceae
The Pinaceae, or pine family, are conifer trees or shrubs, including many of the well-known conifers of commercial importance such as Cedrus, cedars, firs, Tsuga, hemlocks, larches, pines and spruces. The family is included in the order Pinales, formerly known as Coniferales. Pinaceae are supported as monophyletic by their protein-type sieve cell plastids, pattern of proembryogeny, and lack of bioflavonoids. They are the largest extant conifer family in species diversity, with between 220 and 250 species (depending on Taxonomy (biology), taxonomic opinion) in 11 genera, and the second-largest (after Cupressaceae) in geographical range, found in most of the Northern Hemisphere, with the majority of the species in temperate climates, but ranging from subarctic to tropical. The family often forms the dominant component of Boreal forest, boreal, coastal, and montane forests. One species, ''Pinus merkusii'', grows just south of the equator in Southeast Asia.

Cupressus Macrocarpa
''Hesperocyparis macrocarpa'' is a coniferous tree. It is commonly known as the Monterey cypress and is one of several species of cypress trees endemic to California. The Monterey cypress is found naturally only on the Central Coast of California. The natural distributional range of the species during modern times is confined to two small relict populations near Carmel, California, at Cypress Point in Pebble Beach and at Point Lobos. Historically during the peak of the last ice age, Monterey cypress would have likely comprised a much larger forest that extended much further north and south.Axelrod, D. I. (1982)AGE AND ORIGIN OF THE MONTEREY ENDEMIC AREA.''Madroño'', ''29''(3), 127–147. Description ''Hesperocyparis macrocarpa'' is a medium-sized coniferous evergreen tree, which often becomes irregular and flat-topped as a result of the strong winds that are typical of its native area. It grows to heights of up to 40 meters (133 feet) in perfect growing conditions, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
