What does pappous mean?
Pappous is a chiefly botanical adjective meaning that a plant structure bears a pappus. A pappus is a tuft of fine hairs, bristles, or other appendages associated with fruits and seeds, often helping them disperse through wind or contact with animals. The adjective is especially used for an achene or other small fruit carrying such a structure. For example, a botanist might describe the pappous fruits of an aster as specially adapted for wind dispersal. Pappous is more specialized and exact than “hairy,” because it identifies a particular botanical structure rather than merely describing the general texture of an organ. Although uncommon in general writing, the word is valuable in descriptions of plant morphology, seed dispersal, and taxonomic characteristics. It should not be confused with the noun pappus, which names the structure itself rather than indicating that something bears one.

Where does pappous come from?
English pappous was formed from pappus with the adjectival suffix -ous. The noun pappus was borrowed into New Latin from Ancient Greek πάππος (pápppos), “down” or “fluff,” reflecting the fine material that forms such tufts. Its botanical use developed for the hairlike or bristlelike structures associated with certain fruits and seeds, while the English adjective describes objects bearing those structures.
How pappous is actually used
Chiefly botanical and technical, usually used attributively before a noun. It is more formal than ordinary alternatives such as “hairy” or “downy,” although those alternatives may not describe the structure precisely.
