12. PANCEATIUM. Perianth funnel-shaped, the tube generally long, the segments nar- 

 row and erect-spreading. Involucral bracts 2, thin. Cup uniting the filaments bear- 

 ing teeth or lobes between. Ovules many in each cell. Flowers generally umbellate. 

 Leaves linear or strap-shaped.

 linear and recurved. Involucral bracts 2 or more, scarious. Cup not toothed. 

 Ovules 2 in each cell. Flowers white, fragrant, in an umbel-like cluster. Leaves 

 strap-shaped. 



14. EUCHARIS. Perianth tube straight or curved, the segments broad and spreading. 



Cup entire or toothed between the filaments. Bracts several or many, the 2 or 3

* * * Stems leafy, or scape beset with bracts, from a tuberous rootstock or crown. 

 +- Perianth tube 0. 



15. ALSTRGEMERIA. Stems slender and weak or disposed to climb, leafy to the top, the 



thin lanceolate or linear leaves commonly twisting or turning over. Flowers in a

2. NARCISSUS. (Greek name, that of the young man in mythology 

 who is said to have been changed into this flower.) Popular ornamental 

 bulbous plants, running into many varieties and much confused by 

 hybridization. Following are the chief horticultural types : 



* Crown as long as the divisions of the perianth, or longer. DAFFODILS. 

 - Leaves flat, glaucous. 



N. Pseudo-Narcissus, Linn. DAFFODIL, TRUMPET D. Scape 1-flowered,
