Texture and Appearance:
- Pubescent = short, soft hairs
- Scabrous = hard, short, rigid hairs (sandpapery)
- Tomentose = dense, short, rigid hairs
- Felty = densely tomentose
- Hispid = bristly hairs
- Silky = close-pressed, soft and straight hairs
- Glandular-hispid = sticky glands on the hair tips, or stalked glands (stipitate-glandular)
- Woolly = long, tortuous or matted hairs
- Bristly = stiff, strong trichomes
Glaucous surfaces have a whitened or pale color, sometimes caused by a powdery or waxy bloom. When blooms are present, these pale waxy coverings rub off easily with handling, as in blueberry fruit or raspberry canes.
Aromatic properties are found in fresh sap fluids and are best ascertained from scraping or bruising of tissues. Identification of potentially poisonous plants is recommended before experimentation in this area.
