MYRISTICACEAE

Current Angiosperm Phylogeny Group Tree for Flowering Plants 2010 magnoliids monocots

Magnoliales and the relations of the Myristicaceae (APG)

Key characters for the Myristicaceae branches in whorls of four branched hairs reddish resin in bark reduced, fused perianth one-seeded dehiscent berry with aril

Virola – four- branch whorls

Virola –neotropical; glaucous below and covered with branched hairs, fruits typical of the family

Virola --- branched hairs (again)

Epicatechin (an antioxidant) is the key component of Virola resin The red “sap” of the Myristicaceae Is a water-soluble flow from wounds that includes an ethenol-soluble resin…

EFFECTS OF VIROLA SNUFF are felt within minutes from the time of initial use. First there is a feeling of increasing excitability. This is followed by a numbness of the limbs, a twitching of the face, a lack of muscular coordination, nasal discharges, nausea, and, frequently, vomiting. Macropsia - the sensation of seeing things greatly enlarged - is characteristic and enters into Waika beliefs about the spirits resident in the drug Richard Evans Schultes

5-MeO-DMT a tryptamine alkaloid from Virola serotonin, the neurotransmitter trytamine alkaloid backbone

Myristica- the nutmeg --- imperfect, incomplete flowers with fusion

Myristica fragrans - nutmeg and mace

Myristica dispersed by pigeons in the genus Ducula - and in the past by dodos.
