Alkaloids are a class of naturally occurring organic compounds that mostly contain basic nitrogen atoms. This group also includes some related compounds with neutral and even weakly acidic properties. Some synthetic compounds of similar structure may also be termed alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and, more rarely, other elements such as chlorine, bromine, and phosphorus.
A cyclops is a one-eyed monster in Greek mythology.
The Faboideae are a subfamily of the flowering plant family Fabaceae or Leguminosae. An acceptable alternative name for the subfamily is Papilionoideae, or Papilionaceae when this group of plants is treated as a family.
Fynbos is a small belt of natural shrubland or heathland vegetation located in the Western Cape and Eastern Cape provinces of South Africa. This area is predominantly winter rainfall coastal and mountainous areas with a Mediterranean climate. The fynbos ecoregion is within the Mediterranean forests, woodlands, and scrub biome. In fields related to biogeography, fynbos is known for its exceptional degree of biodiversity and endemism, consisting about 80% species of the Cape floral kingdom where nearly 6,000 of them are endemic. This land has faced severe threats and still does, but due to the many economic uses conservation efforts are being made to help restore it.
Holoprosencephaly (HPE) is a cephalic disorder in which the prosencephalon fails to develop into two hemispheres. Normally, the forebrain is formed and the face begins to develop in the fifth and sixth weeks of human pregnancy. The condition also occurs in other species.
Cyclopia intermedia is a species of flowering plant in the legume family.
"A Bicyclops Built for Two" is the thirteenth episode in the second season of the American animated television series Futurama. It originally aired on the Fox network in the United States on March 19, 2000.
Cyclopamine (11-deoxojervine) is a naturally occurring chemical that belongs in the family of steroidal alkaloids. It is a teratogen isolated from the corn lily that causes fatal birth defects. It prevents the fetal brain from separating into two lobes, which in turn causes the development of a single eye (cyclopia). The chemical was named after this effect, as it was originally noted by Idaho lamb farmers who contacted the US Department of Agriculture after their flocks gave birth to cycloptic lambs in 1957. It then took more than a decade to identify the corn lily as the culprit. Later work suggested that different rain patterns caused the sheep to graze differently, impacting the amount of corn lily ingested by pregnant sheep. The poison interrupts the sonic hedgehog signaling pathway during development, thus causing birth defects.
Jervine is a steroidal alkaloid with molecular formula C27H39NO3 which is derived from the plant genus Veratrum. Similar to cyclopamine, which also occurs in the genus Veratrum, it is a teratogen implicated in birth defects when consumed by animals during a certain period of their gestation.
Veratrum is a genus of flowering plants in the family Melanthiaceae. It occurs in damp habitats across much of temperate and subarctic Europe, Asia, and North America.
Veratrum californicum is a poisonous plant native to mountain meadows at 3500 to 11,000 ft elevation in southwestern North America, the Sierra Nevada and Rocky Mountains, and as far north as Alaska and as far south as Durango. It grows 1 to 2 meters tall, with an erect, unbranched, heavily leafy stem resembling a cornstalk. It prefers quite moist soil, and can cover large areas in dense stands near streams or in wet meadows. Many inch-wide flowers cluster along the often-branched top of the stout stem; they have 6 white tepals, a green center, 6 stamens, and a 3-branched pistil. The buds are tight green spheres. The heavily veined, bright green leaves can be more than a foot long.

In teratology, proboscis is a blind-ended, tubelike structure, commonly located in the middle of the face.
Rooibos wine is a variety of wine in which wood from the rooibos and honeybush plants is used instead of the traditional oak wood during the maturation phase. It has its origin in the Western Cape, South Africa. The wine has a unique flavor component and due to the anti-oxidative effect of the plants can be produced without the use of sulfur dioxide.
