Red List 1989:

This species has a threatened status and is listed in the Flora section of the National Red Data Book (Lanfranco, 1989)

Poison:

Yes - Whole plant (especially the seeds) contains very toxic substances.

The leaves are stalked and grows in an alternating fashion along the stems. They are formed in sets of 3 leaflets (trifoliate) each having a simple pinnate venation. The leaflets are nearly identical, with the central one being slightly larger. They large leaflets are often about 35mm long and 12mm wide. Leaflets have an entire outline and a lanceolate shape, sometimes fusiform (elliptical shape). In Summer the leaves are dropped and grow again the following Autumn after the first rains, hence making the plant to be described as deciduous. The short, inconspicuous and apressed stipule is found opposite the leaf.

The flowers are arranged in racemes, with 5-12 flowers per raceme. Each flower have a 8-12mm long pedicel followed by a gamosepalous (fused-sepals) calyx and yellow-green corolla. The bell-shaped calyx have 5 teeth (or triangular lobes) where the upper 2 being smaller and more near to each other.

As in most Fabaceae species, the corolla is basically composed of 5 petals, the upper standard, 2 lateral wings, and 2 central and lower ones known as the keel. These are compact and apressed to form a closed tube. The standard has a circular shape with a diameter of about 12-13mm and is the only petal which is decorated with dark brown or black blob, or strictly speaking a collection of smaller blobs close to each other. The wings and keel are of same oblong shape, about 16mm long, undecorated with longitudinal veins.

Most of the reproductive organs are hidden inside the corolla tube. There are 10 free stamens (with yellow anthers) of unequal length arranged as a bundle around the central pistil. The latter consists of an elongated superior ovary, and a long style with its tip (stigma) usually found protruding out from the corolla.

The ovary develops into a flattened legume which varies in length and number of seeds - 3-12 per pod. The longest legumes are about 15-18cm long and 15-20mm wide. They are more or less oblong structures (with rounded ends), curved backwards and somehow crooked. The seeds can be seen bulging out in the narrow pods (just 3mm wide). The legume has a thread-like tip, previously the style of the flower.

The legumes matures in Summer where they become brown and dehisce to release the seeds inside. The seeds are broad, kidney-shaped structures about 14mm long, 9mm wide and 5mm broad. Normally, they have a dark-purple to black colour, very hard and smooth surface.

Pollination of Anagyris foetida by birds

The pollination of Anagyris foetida L. (Fabaceae), a Mediterranean species that is a relict of the Tertiary, was studied in two populations of SW Spain over a three-year period. Numerous censuses of birds and insects were carried out, the floral nectar was quantified, and specific tests were performed to determine the pollinators' pollen load, the pollen's effective transfer to the pistil, and spontaneous self-pollination. The most important pollinators were three species of passeriforms Phylloscopus collybita Vieillot, Sylvia atricapilla L. and S. melanocephala Gmelin - a result coherent with findings in populations of S and E Spain. The negligible existence of insect visitors and pollinators of A. foetida flowers could be explained by the early flowering of this species during the autumn-winter, coinciding with the coolest and wettest months of the year (cold, high winds, almost daily mists that persist until nightfall, and above all, abundant rainfall). The pollen loads carried by the birds were high, as were also the loads transferred to the pistil. The fruit-set of bagged flowers was very low, evidence of the plant's need for the birds as pollinators. This is the first proof of the existence of a native European bird-pollinated plant, since besides ifs peculaliarities (flowers odourless, pseudotubular, with no landing platform, pendulous, diurnal populations were mainly pollinated by three passeriform species.  [388]

The alkaloid anagyrine from Anagyris foetida

Hardy and Gallois have separated from Anagyris foetida an alkaloid, anagyrine. Parthiel and Spasski found that the crude alkaloid could be separated into cytisine, C11H14N2O and anagyrine, C15H22N2O; the latter is not obtainable in crystalline form; it forms a brittle, resinous-like mass easily reducible to a yellowish powder, but rapidly absorbs moisture and becomes sticky. It volatilizes at 245� C. (473� F.). (Arch. d. Pharm., 244, No. 1, 1906, 20.) It forms, however, a crystalline hydrobromide.  [387] Anagyrine hydrobromide, which has the formula C14H18N2O2HBr, occurs in colorless or faintly yellow crystals and soluble in water. Anagyrine, according to Loewi (A. I. P., vol. vii, p. 66), is physiologically related to lobeline, acting primarily upon the nerve endings as a paralyzant and later upon nerve centers, but having no direct influence upon the muscles. It lessens the cardiac frequency and decreases the force of the systole in the frog, but is said in the mammal to have very little influence upon the blood pressure, death occurring through respiratory paralysis.  [387]

Cytotoxic constituents from Anagyris foetida leaves.

Anagyris foetida extracts were investigated in preliminary cytotoxic tests against two tumour cell lines. Chromatographic separations on active extracts led to the isolation of two alkaloids, anagyrine (1) and baptifoline (2), as well of isorhamnetin (3) and syringin 4-O-beta-D-glucopyranoside (4). In vitro cytotoxicity of compounds 1-3 was also evaluated.  [390]

Rhombifoline and 5,6-dehydroLupinine from Anagyrus foetida

Rhombifoline and 5,6-dehydroLupinine were isolated for the first time from the leaves and stems of A. foetida L. indigenous to Saudi Arabia. In addition, five other alkaloids, previously identified in A. foetidia L., namely N-methylcytisine, sparteine, anagyrine, Lupinine and cytisine, were isolated. The isolated alkaloids were characterized by UV, 1H-NMR, 13C-NMR and Mass spectral data. 13C-NMR data of rhombifoline and 5,6-dehydroLupinine are reported for the first time.  [391]

Toxicity Notes

The following toxicity notes about A. foetida were extracted frm reference  [WWW-173] :

Toxic parts: all but particularly seeds

Active ingredients: two alkaloids, the cytisine and the anagyrine

Circumstances of intoxication: ingestion by the man at the time of confusion with bean pods and consumption by the cattle

Toxicity: described in the child like in the horses and the bovines and sheep (more rarely because the odor of the shrub is dissuasive)

Target body: Nervous system (ganglionic poison)

Symptoms: they appear 4 to 5 a.m. after the seed ingestion: mydriase, excitation, driving incoordination and giddinesses, associated sudation, salivation, colics and convulsions. In the severe cases, the coma then death by asphyxiation occur in the 4 hours after the appearance of the symptoms. The ingestion of sheets involves vomiting and a violent purging.

Livestock productions: elimination of the cytisine in the milk which becomes toxic and present yellow clots.

Main Toxic alkaloids of A. foetida

From the chapters above, the most important toxic alkaloids present in the Stinking bean trefoil are Sparteine, Lupinine, Anagyrine, and Cytisine of which the last two are the most dangerous.

Sparteine: This is a class 1a antiarrhythmic agent  [WWW-60] , an alkaloid isolated from lupin beans, Lupinus luteus and Lupinus niger. It has been used as an oxytocic and an anti-arrhythmia agent. It has also been of interest because of genetic variation in its metabolism. [WWW-174]

Lupinine: The seed of modern cultivars of Lupinus angustifolius normally contain less than 0.03% alkaloids. The acute oral LD50 to rats of a pro rata mixture of the alkaloids of L. angustifolius seed was found to be 2279 mg/kg. For Lupinine the LD50 by oral administration was 1464 mg/kg and by intraperitoneal injection 177 mg/kg. For 13-hydroxyLupinine the LD50 by intraperitoneal injection was 199 mg/kg. Since these two alkaloids comprise about 85% of the total and are known to be rapidly cleared from the body it is suggested that the alkaloids in this species do not pose a health problem for man.  [393] Lupinine, a quinolizidine alkaloid, induces nicotinic effects in animals. Leaves, seeds and fruits all contain lupinine, which is retained in dried plants. Pods may concentrate the toxin, becoming a source of poisoning during the winter season when livestock are moved through infested areas or contaminated hay is fed.  [WWW-135] . Lupinine is reported to cause the following symptoms: Birth defects, spasms, vomiting, nausea, dizziness, headache, abdominal pain, & in severe cases death.  [WWW-176]

Anagyrine: C15H20N2O A toxic alkaloid found in several species of Lupinus in the western United States; acute poisoning produces nervousness, depression, loss of muscular control, convulsions, and coma.  [WWW-125] This alkaloid causes the "crooked calf syndrome" (i.e., carpal flexure, torticollis and scoliosis in calves exposed in utero during days 40-70 of gestation).  [WWW-135]

Cytisine: Cytisine is a toxic pyridine-like alkaloid. Pharmacologically it exhibits similar effects to nicotine due to structural similarity of the two molecules. In large doses it can interfere with respiration and become fatal.  [WWW-60] Cytisine is a nicotine agonist, and as a pharmaceutical preparation it is available for the treatment of nicotinism. Cytisine derivative varenicline was approved in 2006 as a smoking cessation drug. A 2006 literature review concludes that while trials performed with cytisine itself are mostly of poor quality, there is some evidence that cytisine may be prescribed to aid in smoking cessation. [WWW-125] Cytisine is reported to cause the following symptoms: Nausea, vomiting, abdominal pain, diarrhea, drowsiness, headache, dizziness, fever, irregular heartbeat, dilated pupils. Severe cases can have convulsions, coma & death. The toxicity varies widely.  [WWW-176]

Plants containing cytisine, including the Common Broom and Mescalbean have also been used recreationally. Positive effects are reported to include a mild intoxication and heightened awareness of color. However this practice is not recommended since negative side-effects can include nausea, vomiting, convulsions, heart pain, headache and in larger doses even death via respiratory failure. Plants that contain the alkaloid in various concentrations include several from the Faboideae subfamily, including laburnum, anagyris, thermopsis, cytisus, genista and sophora.  [WWW-125]

Cases of toxicity from anagyrine in lupin plants

Silky lupine (Lupinus sericeus) is a native herb of western Canada. This lupine has caused poisoning and death in cattle, goats, horses, and sheep. Sheep eat the plants more readily than do other animals and are therefore more commonly poisoned. Cattle also suffer from crooked calf disease, a teratogenic syndrome caused by maternal ingestion of certain lupines between day 40 and day 70 of gestation. The calves can suffer from arthrogryposis, scoliosis, and other deformities. Humans are also at risk from lupine toxins. In one case in California, a child was born with limb deformities. The family raised milk goats that had also given birth to kids with deformed limbs, and a dog gave birth to deformed pups. All had ingested the goat''s milk during pregnancy. Anagyrine in a local lupine species was believed to cause the problem. Tests showed that lactating goats that ingest lupine seeds pass anagyrine in the milk. Edible lupine seeds are being marketed in health food stores. In Edmonton (Smith 1987), a woman suffered mild dizziness and incoordination after ingesting the seeds. She did not follow specific instructions to soak and boil the seeds in several changes of water, which is necessary to remove the toxins.  [WWW-175]

Binding of quinolizidine alkaloids to nicotinic and muscarinic acetylcholine receptors.

Fourteen quinolizidine alkaloids, isolated from Lupinus albus, L. mutabilis, and Anagyris foetida, were analyzed for their affinity for nicotinic and/or muscarinic acetylcholine receptors. Of the compounds tested, the alpha-pyridones, N-methylcytisine and cytisine, showed the highest affinities at the nicotinic receptor, while several quinolizidine alkaloid types were especially active at the muscarinic receptor.  [389]

Personal Observations


The blotch on the standard
On examining several flowers of the same specimen, I found two different types of dark blotches on the standard petal. One type of blotch consisted of a cluster of very small, isolated and well defined specs which where as black as coal. The other type of consisted of a singular iodine-brown blotch. All other blotches fell as gradual intermediates between the two extreme types described. On further study it was noted that the blossoming flower had the former type of blackish blotch and as if the colour diffuses gradually with flower age across the petal to form the other brownish type of blotch. On a similar note, blossomed flowers had a yellow-green corolla while mature ones turn to a more golden hue of yellow.
Odour of the plant
Personally, I do not find the odour of this plant very stinking. It has a strong smell of boiled or cooked beans, but not an unpleasant one.
