Kohleria is a New World genus of the flowering plant family Gesneriaceae.
 The plants are generally tropical herbs or subshrubs with velvety stems and foliage and brightly colored flowers with spots or markings in contrasting colors.
 They are rhizomatous and commonly include a period of dormancy in their growth cycle.
 The genus was recently revised by Kvist & Skog (1992) and was recognized as having 19 species distributed in Central America and South America.
 Recent phylogenetic work by Roalson et al. (2005) indicated that the epiphytic genus "Capanea" is derived from within Kohleria, and the two species of "Capanea" were subsequently transferred to "Kohleria".
 The genus "Pearcea" is closely related.
Gironniera parvifolia is a tree in the family Cannabaceae endemic to Sri Lanka.
Aphananthe aspera, commonly known as scabrous aphananthe or muku tree, is a flowering plant in the family Cannabaceae.
 It is found on slopes and stream banks between 100 and 1600 m.
 It is native to China, Taiwan, Japan, Korea, and Vietnam.
Cystolith (Gr.
 "cavity" and "stone") is a botanical term for the inorganic concretions, usually of calcium carbonate, formed in a cellulose matrix in special cells called lithocysts, generally in the leaf of plants of certain families, e.g. "Ficus elastica", the Indian rubber plant of the family Moraceae.
 Plants in the family Urticaceae, also known as stinging nettles, also form leaf cystoliths, but only during their later flowering and seed setting stages.
 Cannabis and other plants in the family Cannabaceae also produce leaf and flower cystoliths.
In Canada as of early 2017, cannabis – usually referred to as marihuana or marijuana – is legal only for medicinal purposes and only under conditions outlined in the " Access to Cannabis for Medical Purposes Regulations (ACMPR).

 The cultivation of the hemp plant of the genus Cannabis (family Cannabaceae) is currently legal in Canada for seed, grain and fibre production only under licences issued by Health Canada.
The Rose Motif is a collection of plant characteristics utilized for diagnosing plant families in Dr. J. Richard Abbott's field botany course at Murray State University's Hancock Biological Station.
 These characteristics primarily identify the Rosaceae family and then with the addition of other characteristics can be used to identify Betulaceae, Cannabaceae, Fagaceae, and Ulmaceae.
 This approach is not meant to be comprehensive nor exhaustive, but is focused on vegetative features, especially for common plants in eastern North America.
 Rosaceae mostly have relatively showy, perfect flowers with a hypanthium and are often herbaceous, whereas the other families have relatively inconspicuous, unisexual flowers without an obvious hypanthium and are all woody (except for Cannabis & Humulus in the Cannabaceae).
Celtis africana, the white stinkwood, is a deciduous tree in the family Cannabaceae.
 Its habit ranges from a tall tree in forest to a medium-sized tree in bushveld and open country, and a shrub on rocky soil.
 It occurs in Yemen and over large parts of Africa south of the Sahara.
 It is a common tree in the south and east of southern Africa, where the odour given off by freshly-cut green timber is similar to that of "Ocotea bullata" or Black Stinkwood.
Humulus, hop, is a small genus of flowering plants in the family Cannabaceae.
 The hop is native to temperate regions of the Northern Hemisphere.
 Hops are the female flowers (seed cones, strobiles) of the hop species "H. lupulus"; as a main flavor ingredient in beer, "H. lupulus" is widely cultivated for use by the brewing industry.
Aphananthe is a small genus of evergreen trees in the family Cannabaceae.
 Around six species are recognised, found in Madagascar, South-east Asia, Mexico and Australia.
 Leaves are alternate on the stem and toothed.
 Flowers are unisexual, fruit form as drupes.
 The generic name of "Aphananthe" refers to "insignificant flower"s. Species include "Aphananthe aspera" and "Aphananthe philippinensis".
Humulus japonicus, known as wild hop or Japanese hop, synonym "H. scandens" is an ornamental plant in the Cannabaceae family.
 Originally found in temperate parts of Asia (China, Japan, Korea, Taiwan and Russia) and the tropical environment of Vietnam, "Humulus japonicus" was imported to the North America in the 1800s for use in an Asian tonic and as an ornamental plant.
 Since its arrival in North America, Japanese hop has been very successful in spreading in North America.
 It has a wide distribution and can be found throughout the Northeastern U.S. and eastern Canada.
 It is considered an invasive species in North America.
 The composition and chemistry of the oils found in "Humulus japonicus" differs from its relative the common hop, "Humulus lupulus."
 As a result, the Japanese hop is not used in the production of beer.
