Fam. 86. LILIACEJE. 



Usually bulbous or rhizomatons perennial herbs, more 

 rarely tougb climbing shrubs. L. usually parallel- veined, larely 

 net- veined (Sinilas.) or reduced to minute scales or spines 

 (Asparagus) with the leaf function assumed by slender 

 cladodes. Fls. usually 2-sexual (exc. Smilax) and regular. 

 Perianth in two whorls of 3 nfembars, usually similar and 

 petaloid. St. in two whorls of 3 members, rarely more. 

 Ovary superior of 3 carpels, 3-celled with usually many 

 axile anatropous ovules. Seeds albuminous. 



(Note.— A very distinct physiological type of Liliace» is represented 

 by the fleshy or leathery often spiny leaved Aloes, Yuccas and some 

 Dracaenas. Some of these become arborescent and shew a secondary 

 increase in thickness. The Agaveae would appear to be closely allied, 

 and are often called Aloes, but they are placed in the Amaryllidaceaa on 

 account of their distinctly inferior ovary.) 



I. Climbing usually prickly shrubs with- inconspicuous flowers. 

 Anthers introrse.
