Aconitum Degenii
''Aconitum degenii'' is a species of flowering plant in the buttercup family known by the common name branched monkshood . Distribution This wildflower is native to Europe (south, south-east) where it grows in subalpine areas. Inhabited biotops include tall herbaceous vegetation and deciduous forests. Description ''Aconitum degenii'' is a tall spindly erect to scandent forb which is perennial from rhizomes. It has divided leaves. The flowering period extends primarily from July to September. The inflorescence is paniculate and branched. The perigon is blue or purple. The helmet is about as high as it is wide or less high. The nectar leaves have a curved stem. The spur is slightly bent back. The plant reaches a stature height between 0.5 and 2.5 m. The pollination is done by insects ('' Bombus spec.'' and others). The fruits are pod-like follicles.Jäger et al.: ''Rothmaler - Exkursionsflora von Deutschland'', Bd. 2. Aufl. 20, Spektrum akadem. Verlag. ''Aconitum degenii'' is pois ...

Gyula Gáyer
Gyula Gáyer (16 February 1883, in Kiscell, Hungary, Austria-Hungary – 13 June 1932, in Szombathely, Hungary) was a Hungarian botanist, lawyer, and judge. His early education was at Celldömölk. At the age of ten, Gáyer came to Szombathely, where he became a pupil of the Premonstratensian grammar school. He finished high school in Budapest. From 1904, he continued his studies at the university in Cluj-Napoca, where he was called to the bar in 1907. From 1914 onward he was a judge. Botanical work He described several species and subspecies, including several subspecies of ''Aconitum napellus.'' Several plants bear his name: * (Euphorbiaceae) '' Tithymalus × gayeri'' ( Boros & Soó) Holub * (Rhamnaceae The Rhamnaceae are a large family of flowering plants, mostly trees, shrubs, and some vines, commonly called the buckthorn family.

Ranunculaceae
Ranunculaceae (buttercup or crowfoot family; Latin "little frog", from "frog") is a family of over 2,000 known species of flowering plants in 43 genera, distributed worldwide. The largest genera are ''Ranunculus'' (600 species), ''Delphinium'' (365), ''Thalictrum'' (330), ''Clematis'' (325), and ''Aconitum'' (300). Description Ranunculaceae are mostly herbaceous annuals or perennials, but some are woody climbers (such as ''Clematis'') or shrubs (e.g. ''Xanthorhiza''). Most members of the family have bisexual flowers which can be showy or inconspicuous. Flowers are solitary, but are also found aggregated in cymes, panicles, or spikes. The flowers are usually radially symmetrical but are also found to be bilaterally symmetrical in the genera ''Aconitum'' and ''Delphinium''. The sepals, petals, stamens and carpels are all generally free (not fused), the outer flower segments typically number four or five. The outer stamens may be modified to produce only nectar, as in Aqui ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Bombus
A bumblebee (or bumble bee, bumble-bee, or humble-bee) is any of over 250 species in the genus ''Bombus'', part of Apidae, one of the bee families. This genus is the only extant group in the tribe Bombini, though a few extinct related genera (e.g., ''Calyptapis'') are known from fossils. They are found primarily in higher altitudes or latitudes in the Northern Hemisphere, although they are also found in South America, where a few lowland tropical species have been identified. European bumblebees have also been introduced to New Zealand and Tasmania. Female bumblebees can sting repeatedly, but generally ignore humans and other animals. Most bumblebees are social insects that form colonies with a single queen. The colonies are smaller than those of honey bees, growing to as few as 50 individuals in a nest. Cuckoo bumblebees are brood parasitic and do not make nests or form colonies; their queens aggressively invade the nests of other bumblebee species, kill the resident queen ...

Follicle (fruit)
In botany, a follicle is a dry unilocular fruit formed from one carpel, containing two or more seeds. It is usually defined as dehiscing by a suture in order to release seeds, for example in ''Consolida'' (some of the larkspurs), peony and milkweed (''Asclepias''). Some difficult cases exist however, so that the term indehiscent follicle is sometimes used, for example with the genus ''Filipendula'', which has indehiscent fruits that could be considered intermediate between a (dehiscent) follicle and an (indehiscent) achene. An aggregate fruit that consists of follicles may be called a follicetum. Examples include hellebore, aconite, ''Delphinium'', ''Aquilegia'' or the family Crassulaceae, where several follicles occur in a whorl on a shortened receptacle, or ''Magnolia'', which has many follicles arranged in a spiral on an elongated receptacle. The follicles of some species dehisce by the ventral suture (as in ''Banksia''), or by the dorsal suture (as in ''Magnolia'').Kapil, R. ...

Alkaloids
Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. 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.Chemical Encyclopedia: alkaloids xumuk.ru Alkaloids are produced by a large variety of organisms including , , [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Aconitine
Aconitine is an alkaloid toxin produced by various plant species belonging to the genus '' Aconitum'' (family Ranunculaceae), known also commonly by the names wolfsbane and monkshood. Monkshood is notorious for its toxic properties. Aconitine is also present in Yunnan Baiyao, a proprietary traditional Chinese medicine. Uses Aconitine was previously used as an antipyretic and analgesic and still has some limited application in herbal medicine, although the narrow therapeutic index makes calculating appropriate dosage difficult. Structure and reactivity Biologically active isolates from '' Aconitum'' and ''Delphinium'' plants are classified as norditerpenoid alkaloids, which are further subdivided based on the presence or absence of the C18 carbon. Aconitine is a C19-norditerpenoid, based on its presence of this C18 carbon. It is barely soluble in water, but very soluble in organic solvents such as chloroform or diethyl ether. Aconitine is also soluble in mixtures of alcohol an ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
