PRINCIPAL GENERA. 



We have indicated the extremely close affinities tet\\een Liliaceat, Asparagcte and Smilacea ; fami- 

 lies which together form a group to which most other Monocotyledonous families may he linked, directly 

 or by intermediates. Thus Jiinccce, which are near certain MelanihncecB and Liliaceee, connect these 

 with other families with a free ovary ; and on the other hand, those Amaryllidece and Dioscoi-e<s which 



' Methonica belongs !o a very different tribe. See Trite III., Methonicca, of Mdanthaces, p. 8f 3.— Ed.
