Kalanchoe × Laetivirens
''Kalanchoe laetivirens'' is a species of '' Kalanchoe'' (section '' Bryophyllum''). It is most likely a hybrid between '' K. daigremontiana'' and '' K. laxiflora'' (syn. ''Bryophyllum crenatum''), and therefore a group of invalid names for such a hybrid, including ''Kalanchoe crenodaigremontiana'', ''Kalanchoe crenato-daigremontiana'', ''Bryophyllum crenodaigremontianum'' and ''Bryophyllum crenato-daigremontianum'', are just synonyms of ''K. laetivirens''. It is often misidentified as one of its parents, '' K. daigremontiana'', which has bands or spots on the back of leaves, while the leaves of ''K. laetivirens'' are completely green, as indicated by its epithet ''laetivirens'' which means "lushly green".

Kalanchoe
''Kalanchoe'' , also written ''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 s ... [...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 Crassulaceae native to Madagascar. It is a section or subgenus within the genus ''Kalanchoe'', and was formerly placed at the level of genus. This section is notable for 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 of ''Kalanchoe'' rather than a separate genus. The number of species within ''Bryophyllum'' varies with definitions of this section. ''Br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending 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 hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kalanchoe Daigremontiana
''Kalanchoe daigremontiana'', formerly known as ''Bryophyllum daigremontianum'' and commonly called mother of thousands, 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 ''K. laetivirens'', ''K. delagoensis'' and ''K. × houghtonii''. The leaves of '' K. laetivirens'' are completely green, while ''K. daigremontiana'' has bands or spots on the back of leaves. The leaves of '' K. delagoensis'' are linear, while ''K. daigremontiana'' has lanceolate, oblong, ovate or triangular leaves. '' K. × houghtonii'' is a hybrid between ''K. daigremontiana'' and ''K. delagoensis'', therefore has characteristics in between; its leaves are narrower than thos ...

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, inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
