hair-gland

from The Century Dictionary.

• noun One of the minute sebaceous glands of the root of a hair, whose secretion serves to keep it glossy. See cut under hair.
• noun In botany, a viscid, secreting, or odoriferous gland at the tip of a hair. In Droseraceæ, for example, the hair-glands are viscid or watery, whence the name sun-dew, from their resemblance to drops of dew.
