or the filaments united by a web-like or crown like tissue. 



H- Anthers erect, not versatile; perianth tube ; filaments on the ovary at the base of 

 the 6-parted perianth. 



8. GALANTHUS. Scape with usually a single small flower on a nodding pedicel. Peri-

7. ZEPHYRANTHES. Scape stout but low, the flower arising from a simple bract. 



Perianth funnel-form, the tube mostly short ; segments all similar, spreading. Scales 

 amongst the filaments very small or 0. 



I II Scape more than \-fiowered (except rarely in No. 8). 



o Filaments distinct. 

 x Small scales between the filaments. 



8. HIPPEASTRUM. Scape strong and hollow, often tall, the large flowers In an umbel 



(rarely reduced to 1). Bracts 2, involucrate, distinct. Perianth tube long or short, 

 dilated in the throat and more or less declined, the lobes nearly equal and erect- 

 spreading. Scales often wanting on the lower segments. 



x x No scales between the filaments. 



9. CR1NUM. Perianth with a long slender straight or curved tube and 6 mostly long and
