Definition: There is no evidence that the organism produces compounds (allelochemicals) that influence the growth, survival, and reproduction of other organisms.
Definition: The percentage of organic carbon divided by the percentage of total nitrogen in organic material is higher than 59.
Comment: USDA Plants database specifies the organic material as either the above ground biomass of an herbaceous plant or the above ground herbaceous material of a woody plant.
Definition: A taxon is Least Concern when it has been evaluated against the criteria and does not qualify for Critically Endangered, Endangered, Vulnerable or Near Threatened. Widespread and abundant taxa are included in this category.
Definition: A porosity quality inhering in a bearer by virtue of the bearer's being incapable of admitting the passage of gas or liquid through pores or interstices.

Definition: Seed-bearing organ on gymnosperm plants. A type of fruit, usually woody, ovoid to globular, including scales, bracts, or bracteoles arranged around a central axis, especially in conifers and cycads.
Definition: A landform that extends above the surrounding terrain in a limited area. A mountain is generally steeper than a hill, but there is no universally accepted standard definition for the height of a mountain or a hill although a mountain usually has an identifiable summit and a local relief of more than 300m.
Definition: A peatland whose development is mostly independent of basins or topographical features where water collects; it simply covers the landscape like a blanket. Peat develops due to a continuous supply of water from rainfall, maintaining waterlogged conditions on the ground. Blanket bogs are ombrotrophic or rain fed, and as a result their pH lies between 3.5 and 4.2.
Definition: A color hue with medium-low wavelength of that portion of the visible spectrum lying between yellow and blue, evoked in the human observer by radiant energy with wavelengths of approximately 490 to 570 nanometers.
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: an inflorescence with a monopodial growth habit, composed at flowering stage of indeterminate, first order inflorescence axes and sessile, unisexual flowers each subtended by conspicuous inflorescence bracts
Definition: Of seed bank longevity. Seeds germinate in the first favourable season after dispersal. Generally, seed bank longevity is <= 1 yr (no persistent seed bank).

Definition: A convex 3-D shape quality inhering in a bearer by virtue of the bearer's resembling a cone (a 3-D shape with a round cross section that tapers).
Definition: substance or combination of substances that may be administered to human beings (or animals) for treating or preventing disease, or with the intent to make a medical diagnosis or to restore, correct or modify physiological functions.
