Right: Vaginal lubrication sometimes becomes visible after sexual arousal. Vaginal lubrication is a naturally produced fluid that lubricates a woman's vagina.

Marie Iannotti. Definition: A basal leaf is one that grows from the lowest part of the stem. Basal, in general, refers to the base of a structure. Many perennial plants are trimmed back to new basal foliage once the older foliage starts to look tired and worn.
The type of leaf is usually characteristic of a species (monomorphic), although some species produce more than one type of leaf (dimorphic or polymorphic). The longest leaves are those of the Raffia palm, R. regalis which may be up to 25 m (82 ft) long and 3 m (9.8 ft) wide.
