We have indicated the extremely 'close affinities between Liliace<e, Asporageee and Smilaceee ; fami- 

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

 or by intermediates. Thus Juncea, which are near certain Mdanthncece and Liliacete, connect these 

 with other families with a free ovary ; and on the other hand, those Amaryllidece and Dioscorece which 



1 Methonica belongs to a very different tribe. See Tribe III., Methonicece, of Mdanthacea, p. 863. ED.
