Blade
The lamina or flattened, broad part of a leaf, excluding the stalk or petiole; may apply to a petal, or sepal. View Illustration

Blade Surface
Variations in the lamina or leaf blade outer layer can be described by the terms: Rugose or covered with reticulated (network of) veins, spaces between are convex (wrinkled), and the elevations irregular, e.g., B. goegoensis, B. rajah, or Bullate where the surface is irregularly puckered or blistered e.g., B. crispula, or Muricate where surface is with a uniform low obtuse elevation e.g., B. ‘Black Raspberry’, or Pustulate where surface has numerous uniform acute elevations, like pimples e.g., B. ‘Emerald Jewel’, or Foveolate where the surface is pitted with shallow distinct depressions e.g., B. ‘Tom Ment’

Blade Texture
The surface of leaves categorized primarily by the blade relative thickness, Membranous is thin or semi-transparent, Chartaceous is paper thin and opaque, Coriaceous is medium thick, but with the appearance and flexibility of soft leather, Fleshy is a thick, firm, juicy, often brittle (breaking when bent to 90 degrees), and Scarious is shriveled, thin and dry, as in old dried out stipules

Bract

Bulb
Modified underground bud made up of a very short stem covered with leafy scales or layers

Bulbel
Miniature bulb asexually produced about the base of scales of a mature bulb

Bulbils
A miniature bulb produced in leaf axils of a plant. Propagules, in which leaflike organs act as storage organs

Bulblet
Diminutive for bulb
