adventitious budding the year's shoot — a long, thin, 

 climbing stem, with large leaves and small flowers. 

 This dies down in the dry season and the corky cover- 

 ing protects the mass of the plant from drought." 



CORONARIEiE. 



In this series are included the Lily group, the Rush 

 group, and the Pipewort group. 



The perianth is in two whorls, and is petaloid as a 

 rule. The ovary is superior and syncarpous. The 

 seeds possess endosperm. 



Here are included some of the most lovely flowers 

 in the world, of the Order Liliacese, such as the Lily- 

 of-the-Valley, Tulip, Scilla, etc. In the Lily-of-the- 

 Valleyand Rush groups the flowers are hermaphrodite. 

 In the Pipewort group the plant is monoecious. The 

 perianth is six-partite, petaloid in the Lily-of-the- 

 Valley group. There are six stamens in the Lily-of- 

 the-Valley and Rush groups, two to three in the 

 Pipewort group. The ovary is one- to three-celled. 



The fruit is a capsule, berry, etc. The flowers are 

 conspicuous in Liliacese and adapted to insects. In 

 the Rush group they are wind-pollinated. The 

 plants are herbaceous, except Butcher's Broom, which 

 is a shrub. The Liliacese are large bulbous plants. 

 The Rush group consists of marsh plants ; like the 

 Pipewort group some are aquatic.
