"Saxifraga" Natural Recordings by Native Speakers
Saxifraga is a genus of flowering plants in the family Saxifragaceae, commonly known as the saxifrage or rock foams. It includes around 90 species, and is found in the Northern Hemisphere, primarily in the mountainous regions of Europe, Asia, and North America.
The name Saxifraga comes from the Latin words "saxum" (rock) and "frangere" (to break), which refers to the supposed property of some of the species of being able to crack open rocks. The plant's flowers are typically bell-shaped, with 4-6 petals, and can range in color from white to yellow to pink.
Some species of Saxifraga are edible, while others are used in traditional medicine, and are valued for their ornamental flowers and foliage.
The phrase "Saxe-Coburg and Gotha" refers to a former European royal house that was seated in the Duchy of Saxe-Coburg-Saalfeld, which later became the Duchy of Saxe-Coburg and Gotha, a state in the German Empire. The name was associated with several European monarchies.<br><br>In the 19th century, the British royal family changed its name from Saxe-Coburg and Gotha to the House of Windsor in 1917 due to anti-German sentiment during World War I.
Saxegothaea concinna is a monotypic genus of coniferous tree, the yatesia or Andes cedar, in the podocarpaceae family. It is endemic to Chile.
The word "saxicoline" is an adjective derived from the Greek words "saxico" meaning "sand" and "linos" meaning " thread" or "line". In geology, a saxicoline texture refers to a type of sedimentary structure where sedimentary particles such as sand or gravel are arranged in thin, thread-like layers or bands within a rock. This texture is often characteristic of Aeolian (wind-blown) deposits, where sand grains have been redeposited in alternating bands of coarser and finer grains.
The term "saxifragaceous" refers to members of the Saxifragaceae family, a group of flowering plants commonly known as saxifrages. This family consists of about 430 species, which are mostly shrubs and herbaceous perennials found in mountainous regions, often near water. The name "saxifragaceous" comes from the Latin words "saxum," meaning rock, and "frangere," meaning to break. This echoes the fact that many species in this family have deep, fibrous roots that can split rocks, and their scientific name alludes to this unique characteristic.<br><br>Saxifragaceae species often feature showy, fragrant flowers, frequently white, but sometimes pink or purple. The plants also have interest in their foliage, which can be variegated or have striking leaf colors. In some areas, saxifrages are grown for their decorative value in gardens, while others are utilized by horticulturists for their unique appearance and form.<br><br>In addition, saxifrages have medicinal properties and uses, which contribute to their significance in plant science and traditional medicine.
The word "saxifragant" refers to something that has the quality of breaking or shattering stones (from the Latin words "saxum," meaning stone, and "frangere," meaning to break).

Saxitoxin is a potent neurotoxin produced by certain species of dinoflagellates, a type of marine plankton. It is a powerful inhibitor of the sodium channels in nerve cells, which makes it one of the most toxic naturally occurring substances known.<br><br>Saxitoxin is responsible for the paralytic symptoms associated with paralytic shellfish poisoning (PSP), also known as red tide poisoning. Human beings, when they ingest saxitoxin-laced shellfish such as crabs, mussels, scallops, or oysters, can suffer severe neurological problems, respiratory failure, paralysis, and even death in severe cases.<br><br>Tetrodotoxin (TTX) and saxitoxin are the two most dangerous naturally occurring neurotoxins known, with saxitoxin being the most toxic, 6 times more potent than TTX.
