Seed-leaf meaning

The name is derived from the absence of a seed-leaf or cotyledon.

In monocotyledonous plants there is only one seed-leaf or cotyledon, and hence the arrangement is at first alternate; and it generally continues so more or less, rarely being verticillate.

But the cultivation of tobacco is confined almost exclusively to the valleys of the Connecticut and Housatonic rivers, and these lands are constantly and expensively treated with nitrogenous fertilizers; the grades raised are the broad-leaf and the Habana seed-leaf wrappers, which, excepting the Florida growth from Sumatra seed, are the nearest domestic approach to the imported Sumatra.
