The stalks are a light green colour when young and slowly turn olive brown as the plant grows older. The stalks don’t grow any leaves. - The ovule cones form in the axils of the whorled leaves and when mature contain ripe seeds subtended by orange fleshy bracts. The Gnetales form a monophyletic group comprised of three unusual genera of seed plants, Ephedra, Gnetum and Welwitschia. If side effects aren't a problem, the dose can be increased, but shouldn't exceed 130 mg of ephedra (about 8 mg of ephedrine) three times a day. The herb Ephedra is an erect, broom-like shrub that can grow up to 60cm in height. It provides access to nomenclatural, taxonomic, distributional, and biostatus data. Plants of the Ephedra Family The Ephedras produce naked seeds like the pines, but they form on a colored, cup-like structure called a perianth. The Ephedra plant is strong and doesn’t require that much attention. New Zealand customs officials and the New Zealand police, in relation to clandestine methamphetamine manufacture, have seized Ephedra, a plant known to contain high quantities of pseudoephedrine.

Plants of the Ephedra genus, including E. sinica and others, have traditionally been used by indigenous people for a variety of medicinal purposes, including treatment of asthma, hay fever, and the common cold. It's usual to begin with a low daily dose, such as 100 mg of ephedra (about 6 mg of ephedrine). Gnetum and related genera ... Ephedra trifurca - The stems are photosynthetic and bear whorls of small scale-like leaves. NVS maintains a standard set of species code abbreviations that correspond to standard scientific plant names from the Ngä Tipu o Aotearoa - New Zealand Plants database. Ephedra fragilis, commonly named the joint pine, is a species of Ephedra that is native to eastern Mediterranean region of southern Europe and Northern Africa, and from Madeira and the Canary Islands in the Atlantic.. Its habitats are rocky hills and stone walls, where it grows to 6 feet (1.8 m) tall. This Standard lists plants and fungi for the definition of prohibited plant or fungus in section 1.1.2—3. Most standardized extracts supply about 5.5-6.5% ephedrine (also known as 'ephedra alkaloids'). (photo, Iain MacDonald) Ephedra sp. Ephedra is a medicinal preparation from the plant Ephedra sinica.Several additional species belonging to the genus Ephedra have traditionally been used for a variety of medicinal purposes, and are a possible candidate for the Soma plant of Indo-Iranian religion. The National Vegetation Survey (NVS) Databank is a physical archive and electronic databank containing records of over 94,000 vegetation survey plots - including data from over 19,000 permanent plots. Prohibited plants and fungi are regulated by paragraphs 1.1.1—10(3)(a) and (4)(e) and Standard 1.4.4. Statistics. The Plant List includes 157 scientific plant names of species rank for the genus Ephedra.Of these 67 are accepted species names. The Plant List includes a further 79 scientific plant names of infraspecific rank for the genus Ephedra.We do not intend The Plant List to be complete for names of infraspecific rank. Thus it superficially appears that these plants are an evolutionary link between the conifers and the true flowering plants. Their extraordinary morphological diversity suggests they are the sole extant survivors of an ancient, more diverse evolutionary lineage. This information is derived from the New Zealand Plant Names Database and the Allan Herbarium Specimen database.
