Etymology: "Tomentosa" is the feminine form of the Latin adjective "tomentosus," meaning "stuffed" or "full of stuffing," and the Latin noun "tomentum" from which it comes referred to the stuffing for mattresses and cushions, typically made of wool, hair, or plant down. Botanists borrowed the sense for leaves and stems covered in fine, felt-like hair, which is why a tomentose leaf looks as though it has been padded. The Latin root behind "tomentum" is related to "tumere," "to swell," the same idea that gives English "tumor." A cushion and a swelling share a notion of something being filled out. The botanical use is a New Latin extension, applied in the scientific naming of plants rather than inherited from classical Latin texts about plants. The feminine "tomentosa" appears in species names, agreeing with feminine genus names, so it is the form most often seen in plant names such as those in the genus Ficus or Nicotiana. Its use in English is almost entirely technical.
