Definition: Determined for type of life cycle being annual, binneal, perennial etc.
Comment: The life cycle habit indicates the typical duration of an individual plant's life. Common values are annual, biennial, and perennial. Some plants have different durations depending on environment or location, so a plant can have more than one value.
Definition: Of plant duration, a plant whose life span extends over more than two growing seasons, c.f. annual, biennial, ephemeral, of flowering with respect to architecture, hapaxanthic, monocarpic, pleonanthic

Definition: Five indicator statuses, or ratings, are used in the United States National Wetland Plant List to designate a plant species’ preference for occurrence in a wetland or upland: Upland (UPL), Facultative Upland (FACU), Facultative (FAC), Facultative Wetland (FACW), and Obligate Wetland (OBL). The statuses represent the estimated probability of a species occurring in wetlands versus nonwetlands in a region.
