Dandelion coffee In 1919, dandelion root was noted as a source of cheap 'coffee'. It has also been part of edible plant classes dating back at least to the 1970s. Harvesting dandelion roots requires differentiating 'true' dandelions ("Taraxacum" spp.) from other yellow daisy-like flowers such as catsear and hawksbeard. True dandelions have a ground-level rosette of deep-toothed leaves and hollow straw-like stems. Large plants that are 3–4 years old, with taproots approximately 0.5 inch (13 mm) in diameter, are harvested for dandelion coffee. These taproots are similar in appearance to pale carrots. After harvesting, the dandelion roots are dried, chopped, and roasted.
Type genus the genus that provided the stem to which was added the ending -idae (for families). In botanical nomenclature, the phrase "type genus" is used, unofficially, as a term of convenience. In the "ICN" this phrase has no status. The code uses type specimens for ranks up to family, and types are optional for higher ranks. The Code does not refer to the genus containing that type as a "type genus". Type genus In biological classification, especially zoology, the type genus is the genus which defines a biological family and the root of the family name. According to the International Code
