220 ALLIANCES OF PLANTS. 



GROUP I. EPIGYNOS^E. 



Alliance 1 . Amomales. Leaves with the veins diverging from 



the midrib to the margin. 

 Monandrous. Anther two- 232. Zingiberaceae . Aromatic, stimu- 



celled. latin (Ginger}. 



Monandrous. Anther one- 233. Marantaceee . Amylaceous, insi- 



celled. pid (Arrowroot). 



Several anthers . .234. Musaceae . Fruit nutritious 



(Banana). 



Alliance 2. Narcissales. Hexapetaloideous hexandrous 



plants. 

 Flowers large. Texture 235. Amaryllidaceee Acrid. Poisonous. 



smooth. 

 Leaves equitant. Plant 236. Heemodoraceae. 



woolly. 

 Leaves equitant. Fruit 237. Burmanniaceae. 



winged. 

 Fruit 1 -celled. Placentae 238. Taccaceae. 



parietal. 



Alliance 3. Ixiales. Triandrous. 



239. Iridacese . Purgative. 



Alliance 4. Bromeliales. Tripetaloideous scurfy plants (with 

 albumen). 



240. Bromeliacese . Sap sugary (Pine- 



apple). 



Alliance 5. Hydrates. Tripetaloideous smooth plants. Sta- 

 mens more than six. (Albumen absent.) 



241. Hydrocharacese. 



Both Hydrocharaceae and Bromeliaceae pass into Spadicosae by Pandanaceae. Iridaceae, 

 particularly the genus Gladiolus, offer a very near approach in structure to Gynandrosae. 



GROUP II. GYNANDROS.E. 



Ovary one-celled . . 242. Orchidaceae . Aromatic, viscid, 



nutritious (Sa- 

 lep, Vanilla). 



The flowers of a Gladiolus would become those of an Orchis in calyx and corolla and 

 stamens, if the latter were consolidated with the style ; here there is a transition to Epi- 

 gynosse. Apostasiaceae have the nearly regular flowers of Liliacete, and through them 

 connect this group with Hypogynosae.
