Drimia maritima (syn. Urginea maritima) is a species of flowering plant in the family Asparagaceae, subfamily Scilloideae (formerly the family Hyacinthaceae). [3] This species is known by several common names, including squill, sea squill, sea onion, [4] and maritime squill. [5] It may also be called red squill, particularly a form which produces red-tinged flowers instead of white. [5] It is native to southern Europe, western Asia, and northern Africa. [4]
This plant grows from a large bulb which can be up to 20 cm (7.9 in) wide and weigh 1 kg (2.2 lb). Bailey reported weights of up to fifteen pounds (seven kilograms), probably referring to a clump. [6] Several bulbs may grow in a clump and are usually just beneath the surface of the soil. In the spring, each bulb produces a rosette of about ten leaves each up to a meter long. They are dark green in color and leathery in texture. They die away by fall, when the bulb produces a tall, narrow raceme of flowers. This inflorescence can reach 1.5–2 m (4 ft 11 in – 6 ft 7 in) in height. [5] [7] The flower is about 1.5 cm (0.59 in) wide and has six tepals each with a dark stripe down the middle. The tepals are white, with the exception of those on the red-flowered form. The fruit is a capsule up to 1.2 cm (0.47 in) long. [5]
This plant often grows in rocky coastal habitat, especially in the Mediterranean Basin, where it is common. [5] It occurs in many other types of habitat, except for the driest deserts. [7] It can grow in open and also in very shady areas. [8] Its habit of producing leaves in the spring and flowers in the fall is an adaptation to the Mediterranean climate of its native range, where the summers are hot and dry. [9]
This species has two different pollination syndromes, entomophily and anemophily; it is pollinated by insects and wind. Insect pollinators include the western honey bee (Apis mellifera), the Oriental hornet (Vespa orientalis), and the paper wasp species Polistes gallicus . [7]
The plant has been used as a poison and as a medicinal remedy. The main active compounds are cardiac glycosides, including unique bufadienolides such as glucoscillaren A, proscillaridine A, scillaren A, scilliglaucoside and scilliphaeoside. The plant can have a cardiac glycoside content of up to 3%. Scilliroside, the most important of the toxic compounds, is present in all parts of the plant. [10] The broad leaves of this plant, when they completely dry out, lose their toxicity and are consumed by cattle and sheep. [11] In Palestine, Arab peasants are known to use the plant to mark the butts and bounds of farm land, on account of the plant's distinct features. [11] [12] [13]
This species has been used as a medicinal plant since ancient times. It is noted in the Ebers Papyrus of the 16th century BC, one of the oldest medical texts of ancient Egypt. [9] Pythagoras wrote about it in the 6th century BC. [14] Hippocrates used it to treat jaundice, convulsions, and asthma. [5] Theophrastus was also familiar with it. [9] Its primary medicinal use was as a treatment for edema, then called dropsy, because of the diuretic properties of the cardiac glycosides. [15] A solution of sea squill and vinegar was a common remedy for centuries. [15] The plant is also used as a laxative and an expectorant. [5]
The plant has also been used as a poison. It is very bitter, so most animals avoid it. Rats, however, eat it readily, and then succumb to the toxic scilliroside. This has made the plant a popular rodenticide for nearly as long as it has been in use as a medicine. [5] The bulbs are dried and cut into chips, which can then be powdered and mixed with rat bait. The plant was introduced as an experimental agricultural crop in the 20th century primarily to develop high-toxicity varieties for use as rat poison. [9] Interest continued to develop as rats became resistant to coumarin-based poisons. [5] [16]
It has also been tested as an insecticide against pests such as the red flour beetle (Tribolium castaneum). [16]
Pythagoras and Dioscorides hung the bulbs with sprouted leaves outside the door in spring as protection against evil spirits. [5] The bulbs are still gathered and displayed in the winter as part of Greek Christmas and new year's traditions. [17]
The tall inflorescences are used as cut flowers in floristry. [5]
Cardiac glycosides are a class of organic compounds that increase the output force of the heart and decrease its rate of contractions by inhibiting the cellular sodium-potassium ATPase pump. Their beneficial medical uses include treatments for congestive heart failure and cardiac arrhythmias; however, their relative toxicity prevents them from being widely used. Most commonly found as secondary metabolites in several plants such as foxglove plants and milkweed plants, these compounds nevertheless have a diverse range of biochemical effects regarding cardiac cell function and have also been suggested for use in cancer treatment.
Erysimum, or wallflower, is a genus of flowering plants in the cabbage family, Brassicaceae. It includes more than 150 species, both popular garden plants and many wild forms. Erysimum is characterised by star-shaped and/or two-sided) trichomes growing from the stem, with yellow, red, pink or orange flowers and multiseeded seed pods.
Hyacinthoides non-scripta is a bulbous perennial plant found in Atlantic areas from the north-western part of the Iberian Peninsula to the British Isles, and also frequently used as a garden plant. It is known in English as the common bluebell or simply bluebell, a name which is used in Scotland to refer to the harebell, Campanula rotundifolia. In spring, H. non-scripta produces a nodding, one-sided inflorescence of 5–12 tubular, sweet-scented violet–blue flowers, with strongly recurved tepals, and 3–6 long, linear, basal leaves.
Squill is a common name for several lily-like plants and may refer to:
Scilla is a genus of about 30 to 80 species of bulb-forming perennial herbaceous plants in the family Asparagaceae, subfamily Scilloideae. Sometimes called the squills in English, they are native to woodlands, subalpine meadows, and seashores throughout Europe, Africa and the Middle East. A few species are also naturalized in Australasia and North America. Their flowers are usually blue, but white, pink, and purple types are known; most flower in early spring, but a few are autumn-flowering. Several Scilla species are valued as ornamental garden plants.
Scilloideae is a subfamily of bulbous plants within the family Asparagaceae. Scilloideae is sometimes treated as a separate family Hyacinthaceae, named after the genus Hyacinthus. Scilloideae or Hyacinthaceae include many familiar garden plants such as Hyacinthus (hyacinths), Hyacinthoides (bluebells), Muscari and Scilla and Puschkinia. Some are important as cut flowers.
Puschkinia is a genus of four known species of bulbous perennials in the family Asparagaceae, subfamily Scilloideae. It is native to the Caucasus and the Middle East. Puschkinia scilloides is grown as an ornamental bulbous plant.
Calotropis gigantea, the crown flower, is a species of Calotropis native to Cambodia, Vietnam, Bangladesh, Indonesia, Malaysia, Thailand, Sri Lanka, India, China, Pakistan, and Nepal.
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.
Scilliroside is a toxic compound derived from the plant Drimia maritima, which is sometimes used as a rodenticide.
Bowiea, commonly known as climbing-onion, is a genus of bulbous, perennial, succulent plants which thrive in dry and desert regions of eastern and southern Africa, ranging from Uganda to South Africa. It is native to a region stretching from Kenya to Cape Province. It is the 14th most commonly sold medicinal plant in South Africa, used to treat various health conditions. Due to massive harvesting, populations of this plant have been significantly reduced. Because of its high content of potent cardiac glycosides, it is highly poisonous, and deaths of humans and other animals after ingestion are attributed to cardiac arrest. Due to its unique appearance, it is cultivated as a houseplant.
