Delphinium is a genus of about 300 species of perennial flowering plants in the family Ranunculaceae, native throughout the Northern Hemisphere and also on the high mountains of tropical Africa.
Hyoscyameae is an Old World tribe of the subfamily Solanoideae of the flowering plant family Solanaceae.
 It comprises seven genera: "Anisodus", "Atropa", "Atropanthe", "Hyoscyamus", "Physochlaina", "Przewalskia" and "Scopolia".
 All seven genera of the tribe are poisonous and have a long tradition of use as medicinal plants, being rich in tropane alkaloids with anticholinergic properties.
 Furthermore, the genera "Atropa", "Hyoscyamus", "Scopolia" and "Physochlaina" have furnished entheogens - the first three in the historical context of European witchcraft and, more specifically, of the flying ointments employed in such practices, while the similar chemistry of the remaining genera points to the potential for entheogenic use.
 Six of the genera have dry, pyxidial fruits i.e. capsules dehiscing by an operculum and thus resembling a pot with a lid.
 The fruit of the remaining genus "Atropa" is a glossy, juicy berry, making "Atropa" species especially dangerous poisonous plants, since - unlike other Hyoscyameae - their attractive fruits may easily be mistaken for edible berries, particularly by children - as has frequently occurred in the case of "Atropa belladonna", the infamous Deadly Nightshade.
Delphinium elatum is a species of "Delphinium" known by the common name alpine delphinium or candle larkspur.
 There are several popular cultivars covering a range of colours from blue and purple to pink, cream, and white, which are grown as ornamental plants. "D. elatum" is also a source of hybrids.
Samuel Bonsall Parish (1838 - 1928) was a California botanist and curator of the herbarium at Stanford University.
 A number of plants were named in his honor, including "Acanthoschyphus parishii", "Allium parishii", "Atriplex parishii", "Boechera parishii", "Chaenactis parishii", "Cheilanthes parishii", "Delphinium parishii" ssp.
 "pallidum", "Delphinium parishii" ssp.
 "parishii", "Ericameria parishii", "Erigeron parishii", "Eriogonum parishii", "Eschscholzia parishii", "Euphorbia parishii", "Galium parishii", "Grusonia parishii", "Heuchera parishii", "Lycium parishii", "Malacothamnus parishii", "Mimulus parishii", "Orobanche parishii" ssp.
 "brachyloba", "Orobanche parishii" ssp.
 "parishii", "Perideridia parishii", "Phacelia parishii", "Plagiobothrys parishii", "Puccinellia parishii", "Silene parishii", "Solanum parishii", "Stipa parishii", "Symphoricarpos parishii", "Tauschia parishii", "Trichostema parishii", "Viguiera parishii", and others.
Delphinium patens is a species of larkspur known by the common names zigzag larkspur and spreading larkspur.
 It is a wildflower limited mainly to California.
 Though not yet confirmed there, it is expected in Baja California.
 Plants grow typically 20 to 50 centimeters tall and bear up to 36 flowers each.
 The stems are mostly hairless, have reddish bases, and bears leaves on the lower half.
 Each leaf is divided into 3 to 9 lobes.
 The flower has dark blue sepals, the latter ones reflexed.
 The spur at the back of the flower is 4 to 8 millimeters long.
 The cleft at the center of the flower has white or yellowish scattered hairs.
 The elongated fruit is one or two centimeters long and contains pitted seeds.
Delphinine is a toxic diterpenoid alkaloid found in plants from the "Delphinium" (larkspur) and "Atragene" (a clematis) genera, both in the family "Ranunculaceae".
 Delphinine is the principal alkaloid found in "Delphinium staphisagria" seeds – at one time, under the name stavesacre, a very well known herbal treatment for body lice.
 It is related in structure and has similar effects to aconitine, acting as an allosteric modulator of voltage gated sodium channels, and producing low blood pressure, slowed heart rate and abnormal heart rhythms.
 These effects make it highly poisonous (LD 1.5–3.0 mg/kg in rabbit and dog; frogs are ~10x more susceptible), but in very small doses it has some uses in herbal medicine.
Delphinium grandiflorum is a species of "Delphinium" known by the common names Siberian larkspur and Chinese Delphinium.
 It is native to Russia and China.
 There are several popular cultivars in several colours which are grown as ornamental plants, including 'Blue Butterfly', 'Summer Morning', 'Blue Mirror', and 'Summer Stars'.
 Like many other larkspurs, this plant is poisonous.
 It is much shorter and more compact than the more familiar tall "D. elatum", with dispersed flowers, rather than single spikes.
Hottonia is a genus of aquatic flowering plants in the family Primulaceae.
 It comprises two species:
Consolida ajacis (syn.
 "Consolida ambigua", "Delphinium ajacis", "Delphinium ambiguum", doubtful knight's spur, rocket larkspur) is an annual flowering plant of the family Ranunculaceae native to Eurasia.
 It is widespread in other areas, including much of North America, where it was an introduced species.
 It is frequently grown in gardens as an ornamental for its spikes of blue, pink or white flowers.
 It may reach a meter in height.
 Since the aerial parts and seeds of "C. ajacis" have been found to contain diterpenoid alkaloids (see below), including the highly toxic methyllycaconitine, the plants should be considered as poisonous.
Delphinidin (also delphinidine) is an anthocyanidin, a primary plant pigment, and also an antioxidant.
 Delphinidin gives blue hues to flowers in the genera "Viola" and "Delphinium".
 It also gives the blue-red color of the grape that produces Cabernet Sauvignon, and can be found in cranberries and Concord grapes as well as pomegranates, and bilberries.
