Term Definition
Scale Any thin, scarious bract or bracteole (usually representing a vestigial leaf found along the stems of some achlorophyllous plants such as species of Voyria (Gentianaceae); the bracteole subtending a flower of Cyperaceae; in pteridophytes, similar structures most commonly found on the rhizomes and stipe and less commonly on the fronds. Scale
Scallop marks A non-technical term used to describe Irregular, shallow depressions on the external surface of bark. Scallop marks
Scape (scapose) A leafless, often bracteate peduncle that arises from near the base of the plant; e.g., in Xyris (Xyridaceae) and many terrestrial Orchidaceae. Scape (scapose)
Scarious Parchmentlike; thin and dry. Scarious
Scatter-hoarding A type of secondary seed dispersal in which some of the diaspores are carried away and intentionally buried or stored (cached) by scatter-hording animals such as agoutis (Dasyprocta spp.) while the other diaspores are eaten and digested, e.g., the dispersal of Brazil nut seeds by agoutis. Same as dysozoochorous. Scatter-hoarding
Schizocarp A dry fruit that splits into several parts (each called a mericarp), each usually with a single seed; e.g., in Apiaceae, most lianas of Malpighiaceae, some Malvaceae, and Serjania spp. (Sapindaceae). Schizocarp
Secondarily indehiscent fruit Fruits that are hypothesized to have evolved indehiscent fruits from ancestors with dehiscent fruits. Secondarily indehiscent fruit
Secondary hemiepiphyte Referring to a plant (e.g., various species of Araceae) that grows from the ground onto its support and later loses its connection with the ground. Compare with epiphyte, hemiepiphyte, and primary hemipiphyte. Secondary hemiepiphyte
Secondary leaflet The second division of a compound leaf. Secondary leaflet
Secondary pollen presentation The presentation of pollen to the pollinator in a place other than the anther; e.g., on the style of Vochysiaceae. Secondary pollen presentation
Secondary pollen presentation The presentation of pollen to the pollinator in a place other than the anther. Secondary pollen presentation
Secondary rachis The rachis from which the second order of leaflets arise or the flowers from the second order of branching of an inflorescence. Secondary rachis
Secondary vegetation Vegetation that develops after disturbance by humans or forces of nature. Secondary vegetation
Secondary vein A leaf vein arising from the midrib or primary vein. Same as lateral vein. Secondary vein
Secondary vein A secondary vein is the second thickest vein in a leaf which arise from the midrib (= primary vein) (Hickey, 1973). Secondary vein
Secondary vein decurrent Referring to a secondary vein that curves downward along the midrib. Secondary vein decurrent
Secondary venation The second order of venation in a leaf blade, i.e., the veins that arise from the midrib. Secondary venation
Secund Referring to leaves, branches, flowers, or other structures that arise or seem to arise from one side of an axis; e.g., the flowers of Heliotropium (Boraginaceae). Secund
Seed The mature ovule that contains the embryo within the seed coat. Seed
Seed coat (= testa) The outer covering of a seed. Same as testa. Seed coat (= testa)
Seed coat (= testa) The outer covering of a seed derived from the integuments of the ovule. Seed coat (= testa)
Seed dormancy Referring to seeds that do not germinate until some time after they are dispersed. Many species of secondary forests, e.g. species of Cecropia, may remain dormant for years until the right conditions become available for their germination. Seed dormancy
Seed germination lateral The seed germinates from the side. Seed germination lateral
Seed germination terminal The seed germinates at the ends. Seed germination terminal
Seed wing circumferential A wing completely surrounding the circumference of the seed. Seed wing circumferential
