A forb or phorb is an herbaceous flowering plant that is not a graminoid (grass, sedge, or rush). The term is used in biology and in vegetation ecology, especially in relation to grasslands[1] and understory.[2] Typically these are dicots without woody stems.
Etymology[edit]
The word "forb" is derived from Greek phorbḗ (φορβή), meaning "pasture" or "fodder".[3][4] The Hellenic spelling "phorb" is sometimes used, and in older usage this sometimes includes graminids and other plants currently not regarded as forbs.
Guilds[edit]
Forbs are members of a guild—a group of plant species with broadly similar growth form.[5] In certain contexts in ecology, guild membership may often be more important than the taxonomic relationships between organisms.
In informal classification[edit]
In addition to its use in ecology, the term "forb" may be used for subdividing popular guides to wildflowers,[6] distinguishing them from other categories such as grasses, sedges, shrubs, and trees.[7] Some examples of forbs are clovers, sunflowers, daylilies, and milkweed.
Forb Adaptation Zones: Kale and Turnip are examples of Forb adaptations distributed over much of Europe, southern Oceania, northern Asia, and northern North America. In cooler climates, these crops are grown year-round, while in warmer climates, they are used as winter forage.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
