Kalanchoe pinnata, commonly known as cathedral bells, air plant, life plant, miracle leaf, [2] Goethe plant, [3] and love bush, [4] is a succulent plant native to Madagascar. It is a popular houseplant and has become naturalized in tropical and subtropical areas. The species is distinctive for the profusion of miniature plantlets that form on the margins of its leaves, a trait it has in common with some other members of Bryophyllum (now included in Kalanchoe ). [1]
It is a succulent, perennial plant, about 1 m (39 in) tall, with fleshy cylindrical stems and young growth of a reddish tinge, which can be found in flower throughout most of the year. [5]
The leaves of this species are thick, fleshy, elliptical in shape, curved, with a crenate or serrated margin, often reddish. Simple at the base of the stem, the leaves are imparipinnate at the top, 10–30 cm (4–12 in) long, with three to five pairs of fleshy limb lobes.
The leaves are remarkable for their ability to produce bulbils. At their margin, between the teeth, adventitious buds appear, which produce roots, stems and leaves. When the plantlets fall to the ground, they root and can become larger plants. This is a fairly common trait in the section Bryophyllum. The fruits are follicles (10–15 mm) which are found in the persistent calyx and corolla. [6]
The terminal inflorescence is a panicle, with many pendent, red-orange flowers. The calyx is formed of a long tube, red at the base, veined with yellowish green (or green spotted with reddish brown), with four very small triangular lobes at the end. The tubular corolla, with a pronounced constriction separating the subspherical part of the ovoid part, is terminated by four lobes which reaches 5 cm (2.0 in) in length. It is yellowish in color with red-purple streaks. The eight stamens, each about 4 cm (1.6 in) long, are in two whorls, welded on the corolla. The ovary has four carpels, slightly fused together in the center, with slender styles. [7]
Kalanchoe pinnata is native to Madagascar. [2] and has become naturalized in tropical and subtropical areas, inhabiting warm and temperate climates from sea level to 2,600 m (8,500 ft), occupying sites on rock in tropical evergreen and dry deciduous forests, as well as montane forests. It is found in parts of Asia, Africa, Australia, New Zealand, the West Indies, Bermuda, Macaronesia, the Mascarenes, Brazil, Suriname, the Galapagos Islands, Melanesia, Polynesia, and Hawaii. [1] [8] In many of these, such as Hawaii, it is regarded as an invasive species. [9] Much of the reason for the widespread naturalization of this plant can be traced to its popularity as a garden plant.
The plant Kalanchoe pinnata was harvested by Pierre Sonnerat in Isle de France (Mauritius) and communicated to Lamarck who described it in 1786 as the Cotyledon pinnata. Subsequently, the Paris naturalist Christiaan Hendrik Persoon reclassified it in the Kalanchoe (calling it Calanchoe pinnata 1805-1807, with an orthographic variant). It was first published in Syn. Pl. vol.1 on page 446 in 1805. [1] At the same time, in London, the botanist Richard Anthony Salisbury described the same plant from a specimen received from Bengal, under the name of Bryophyllum calycinum, [10] and at the same time created the new genus Bryophyllum. [11]
The specific Latin specific epithet "pinnata" is the feminine form of the Latin adjective pinnatus, meaning "pinnate". [12]
It has several local names in its native Madagascar: falatanantsifaona, malainana, rendadiaka, sodifafana and tsilafafa. [13] In the Philippines, it is known as katakataka or kataka-taka which is an adjective meaning 'astonishing' or 'remarkable'. [14] [15] [16]
The writer Johann Wolfgang von Goethe (1749–1832), who was an amateur naturalist of some repute, was "passionately fond" of this plant and liked to give baby plantlets of the air plant, as gifts to friends who visited his home. He also discussed his air plant at length in an essay in 1817, titled in German : Geschichte meiner botanischen Studien ("History of my botanical studies"). [17]
In temperate regions, Kalanchoe pinnata is grown as an indoor ornamental plant. Like most succulents, it cannot survive hard frost and will not thrive in environments in which the temperature drops below 10 °C (50 °F). It favours well-drained soil, the roots being otherwise susceptible to rot. In the tropics, K. pinnata is grown outdoors in gardens, from which it may escape to become naturalised - often as an invasive weed.
In common with other species belonging to the Crassulaceae (including certain members of the genera Tylecodon , Cotyledon and Adromischus ), Kalanchoe pinnata has been found to contain bufadienolide cardiac glycosides [18] These can cause cardiac poisoning, particularly in grazing animals. [19] [20]
Bryophyllum pinnatum has been recorded in Trinidad and Tobago as being used as a traditional treatment for hypertension. [21]
In traditional medicine, the juice of the leaves is also used for kidney stones, although there is ongoing research and some scientific evidence for this use but further research is required. In the French Antilles, Kalanchoe pinnata called locally as zeb maltet, is used in local application against headaches. For the people of the Amazon, Kalanchoe has multiple uses: the Creoles use it roasted against inflammations and cancer and as an infusion, and as a popular remedy for fevers. The Palikur people of Brazil and French Guiana apply a preparation of the juice of Kalanchoe leaves mixed with coconut oil to their foreheads to treat headache. [22]
Bufadienolide compounds isolated from Bryophyllum pinnatum include bryophillin A, bersaldegenin-3-acetate, and bryophillin C. [23] Bryophillin C also showed insecticidal properties. [24]
Phytochemical studies of Kalanchoe pinnata have identified the presence of triterpenes, steroid, phenanthrene, flavonoid, flavones, chalcones, taraxasterol, aurones, phenolic acid, caffeic acid, syringic acid, malic, oxalic and ferulic acid. Bufadienolides and phenanthrene are toxic compounds. Two calves fed for 48 hours with K. pinnata have been reported to have died due to ataxia and severe cardiac arrhythmia. [25]
Its antibacterial activity has been studied. [26]
Kalanchoe pinnata is a host plant of the Red Pierrot butterfly. [27]
The Crassulaceae, also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crassulacean acid metabolism (CAM). Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium-sized monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus Sedum, and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce, although a few are aquatic.
Vegetative reproduction is a form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules.
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.
Kalanchoe beharensis is a plant species in the succulent genus Kalanchoe, and the family Crassulaceae. Kalanchoe beharensis is native to Madagascar known by local names mongy, rongy and tavitavy.
Bryophyllum 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.
Talicada nyseus, the red Pierrot, is a small but striking butterfly found in the Indian subcontinent and South-East Asia belonging to the lycaenids, or blues family. The red Pierrots, often found perching on its larva host plant, Kalanchoe, are usually noticed due to their striking patterns and colors.
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, 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.
Kalanchoe thyrsiflora is a species of flowering plant native to Botswana, Lesotho, South Africa and Eswatini. This plant is rare in cultivation, and those plants labelled as "Kalanchoe thyrsiflora" in horticulture are mostly another similar species, Kalanchoe luciae.
Cotyledon is one of some 35 genera of succulent plants in the family Crassulaceae. Mostly from Southern Africa, they also occur throughout the drier parts of Africa as far north as the Arabian Peninsula. Ten of its species are mostly confined to South Africa, where unlike Tylecodon, they occur commonly in both the winter and summer rainfall regions. They may be found on coastal flats and rocky hillsides, or as cremnophytes on cliff faces. Their decussate, evergreen leaves are very variable in shape, even within some species, but the flowers are, apart from colour, very similar.
Cotyledon orbiculata, commonly known as pig's ear or round-leafed navel-wort, is a South African succulent plant belonging to the genus Cotyledon.
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, it is able to propagate vegetatively from plantlets that develop on its leaf margins.
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word succulent comes from the Latin word sucus, meaning "juice" or "sap".
Cotyledon tomentosa is a species of flowering plant in the family Crassulaceae, native to South Africa. It is a succulent evergreen shrub with large chunky ovate fuzzy green leaves. Its autonymous subspecies is known as the bear's paw because of the prominent "teeth" at the tips of its leaves. It forms large orange bell-shaped flowers in spring. In its native habitat, the Little Karoo region of South Africa, Cotyledons usually grow in rocky quartz fields where they have excellent drainage provided by very porous soil.
Kalanchoe fedtschenkoi, formerly known as Bryophyllum fedtschenkoi, native to Madagascar, is widely sold as a house or garden plant that has established itself in the wild in some southern parts of the United States of America. Its specific epithet fedtschenkoi honors botanist Boris Fedtschenko (1873-1947).
Alloxylon pinnatum, known as Dorrigo waratah, is a tree of the family Proteaceae found in warm-temperate rainforest of south-east Queensland and northern New South Wales in eastern Australia. It has shiny green leaves that are either pinnate (lobed) and up to 30 cm (12 in) long, or lanceolate (spear-shaped) and up to 15 cm (5.9 in) long. The prominent pinkish-red flower heads, known as inflorescences, appear in spring and summer; these are made up of 50 to 140 individual flowers arranged in corymb or raceme. These are followed by rectangular woody seed pods, which bear two rows of winged seeds.
Dracaena pinguicula, synonym Sansevieria pinguicula, also known as the walking sansevieria, is a xerophytic CAM succulent native to the Bura area of Kenya, near Garissa. The species was described by Peter René Oscar Bally in 1943.
Kalanchoe longiflora, also known as tugela cliff-kalanchoe or long-flower kalanchoe, is a species of the succulent genus Kalanchoe, in the family Crassulaceae. An obscure shrub native to South Africa, it is known for its multi-coloured foliage and yellow flowers, which bloom in autumn to winter.
Kalanchoe suarezensis is a species of Kalanchoe native to northern Madagascar.
Kalanchoe mortagei is a species of Kalanchoe native to northern Madagascar. It is very similar to K. suarezensis, and both of them used to be mistakenly treated as varieties of a totally different species K. poincarei. K. mortagei differs by having auriculate to peltate leaves, while the leaf base of K. suarezensis is attenuate to truncate.
Kalanchoe sexangularis, also known as bushveld kalanchoe, six-angled kalanchoe, or red-leaved kalanchoe, is a species of the succulent genus Kalanchoe, in the family Crassulaceae that is native to Southern Africa.
