Kalanchoe × Houghtonii
''Kalanchoe'' × ''houghtonii'' is a hybrid between '' Kalanchoe daigremontiana'' and ''Kalanchoe delagoensis'' named after Arthur Duvernoix Houghton. It is often confused with ''Kalanchoe daigremontiana'' which has strongly cordate to auriculate or even peltate The following terms are used to describe leaf plant morphology, morphology in the description and taxonomy (biology), taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade ... leaves, while the leaves of ''Kalanchoe'' × ''houghtonii'' are narrower and the leaf base is attenuate, cuneate to weakly cordate or auriculate. In hortuculture, it is often mislabelled as '' Kalanchoe serrata'', which is a different species.

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Kalanchoe Daigremontiana
''Kalanchoe daigremontiana'', formerly known as ''Bryophyllum daigremontianum'' and commonly called mother of thousands, alligator plant or Mexican hat plant, is a succulent plant native to Madagascar. Like other members of '' Bryophyllum'' (now included in the genus ''Kalanchoe''), it can propagate vegetatively from plantlets that develop on its leaf margins, as well as through upshoots from lateral roots, and seeds. All parts of this species contain a very toxic steroid known as daigremontianin. It is often confused with ''Kalanchoe laetivirens'', ''Kalanchoe delagoensis'' and ''Kalanchoe × houghtonii''. The leaves of '' Kalanchoe laetivirens'' are completely green, while ''Kalanchoe daigremontiana'' has bands or spots on the back of leaves. The leaves of '' Kalanchoe delagoensis'' are linear, while ''Kalanchoe daigremontiana'' has lanceolate, oblong, ovate or triangular leaves. '' Kalanchoe × houghtonii'' is a hybrid between ''Kalanchoe daigremontiana'' and ''Kalanchoe d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kalanchoe Delagoensis
''Kalanchoe delagoensis'', formerly known as ''Bryophyllum delagoense'' and commonly called mother of millions or chandelier plant, is a succulent plant native to Madagascar. Like other members of ''Bryophyllum'' (now included in ''Kalanchoe''), it is able to propagate Vegetative reproduction, vegetatively from plantlets that develop on its leaf margins. Description It is a robust, completely bare, biennial plant, biennial or more or less perennial, succulent plant that reaches heights of between 0.2 and 2 meters. The upright stems are simple and round. The three-seated, seemingly opposite or alternate leaves are usually upright to straight when spread out. They are slightly cylindrical, a little rutty on the top and reach a length of 1 to 13 centimeters with a diameter of 2 to 6 millimeters. The leaf blade narrowed at the base is reddish-green to gray-green with reddish brown spots. At the tip of the leaf margin there are two to nine small teeth on which there are numerous bro ...

Arthur Duvernoix Houghton
Arthur Duvernoix Houghton (June 8, 1870 - January 23, 1938) was a medical doctor, a botanist specializing in cacti, a member of the Los Angeles, California, City Council from 1904 to 1906 and one of the founders of the American Legion. In his early years he was a showman who presented performances in hypnotism and conducted seances. Personal Houghton was born in London, England, on June 8, 1871, and was educated at Oxford University and the Royal Military School of Engineers. He served in the British Army. Houghton had a medical degree and a doctorate of philosophy. He lived in Chicago, Illinois, where he was secretary of the South Side Business Men's League, and he was said to be in Los Angeles in November 1894, when he conducted seances in that city. He moved to Los Angeles around 1902. He was married to Florence Gildersleeve of Chicago in June 1913. Houghton played the role of Doctor Caius, a French physician, in a benefit Los Angeles performance of William Shakespeare ...

Auriculate
The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). The edge of the leaf may be regular or irregular, and may be smooth or have hair, bristles, or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kalanchoe Serrata
''Kalanchoe'' ( ), (also called "kalanchöe" or "kalanchoë"), is a genus of about 125 species of tropical, succulent plants in the stonecrop family Crassulaceae, mainly native to Madagascar and tropical Africa. A ''Kalanchoe'' species was one of the first plants to be sent into space, sent on a resupply to the Soviet Salyut 1 space station in 1979. The majority of kalanchoes require around 6–8 hours of sunlight a day; a few cannot tolerate this, and survive with bright, indirect sunlight to bright shade. Description Most are shrubs or perennial herbaceous plants, but a few are annual or biennial. The largest, '' Kalanchoe beharensis'' from Madagascar, can reach tall, but most species are less than tall. Kalanchoes open their flowers by growing new cells on the inner surface of the petals to force them outwards, and on the outside of the petals to close them. Kalanchoe flowers are divided into 4 sections with 8 stamens. The petals are fused into a tube, in a similar way to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bryophyllum
''Bryophyllum'' (from the Greek ''bryon/bryein'' = sprout, ''phyllon'' = leaf) is a group of plant species of the family (biology), family Crassulaceae native to Madagascar. It is a Section (botany), section or subgenus within the genus ''Kalanchoe'', and was formerly placed at the level of genus. This section is notable for Vegetative reproduction, vegetatively growing small plantlets on the fringes of the leaves; these eventually drop off and root. These plantlets arise from mitosis of meristematic-type tissue in notches in the leaves. Nowadays, bryophyllums are naturalized in many parts of the tropics and subtropics, and deliberately cultivated for their attractiveness or for their interesting reproduction as a vegetative reproductive plant. Taxonomy Species of ''Bryophyllum'' are nested within ''Kalanchoe'' on molecular phylogenetic analysis. Therefore, ''Bryophyllum'' should be a section or subgenus of ''Kalanchoe'' rather than a separate genus. The number of species ...

Flora Of Madagascar
The flora of Madagascar consists of more than 12,000 species of plants, as well as a poorly known number of fungi and algae. Around 83% of Madagascar's vascular plants are found only on the island. These endemics include five plant families, 85% of the over 900 orchid species, around 200 species of palms, and such emblematic species as the traveller's tree, six species of baobab and the Madagascar periwinkle. The high degree of endemism is due to Madagascar's long isolation following its separation from the African and Indian landmasses in the Mesozoic, 150–160 and 84–91 million years ago, respectively. However, few plant lineages remain from the ancient Gondwanan flora; most extant plant groups immigrated via across-ocean dispersal well after continental break-up. After its continental separation, Madagascar probably experienced a dry period, and tropical rainforest expanded only later in the Oligocene to Miocene when rainfall increased. Today, humid forests, includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
