AMARYLLIS FAMILY. 425 



* Scape and linear hairy leaves from a little solid bulb or corm. 



1. HYPOXIS. Perianth 6-parted nearly to the ovary, spreading, greenish outside, yellow 



within, persistent and withering on the pod. 



* * Scape and mostly smooth leaves from a coated bulb, the stem leafless or nearly so. 

 +- A cup-shaped, funnel-shaped, or saucer-shaped crown on the throat of the perianth. 



2. NARCISSUS. Perianth with a more or less cylindrical tube, 6 equal widely spreading 



divisions, and stamens of unequal length included in the cup or crown. Scape with 

 one or more flowers, from a scarious 1-leaved spathe. 



K +- No true crown in the throat of the perianth, but sometimes represented by scales, 

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



++ 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- 

 anth of 6 oblong separate concave pieces ; the three inner shorter, less spreading, 

 and notched at the end. Anthers and style pointed. 



4. LEUCOIUM. Scape bearing 1-7 flowers on nodding pedicels. Perianth of 6 nearly 



separate oval divisions, all alike. Anthers blunt. Style thickish upwards. 



H- ++ Anthers fixed by the middle and versatile ; perianth tube often evident or long; 

 filaments borne on the perianth. 



= Perianth tube 0, or exceedingly short. 



5. SPEEKELIA. Scape strong and tall, mostly 1-flowered, the bract one and spathe-like. 



Flower very showy, with no tube, the upper segments ascending and the lower ones 

 concave. Scales between the filaments small. 



6. NERINE. Scape strong, several- or many-flowered, the perianth tube nearly obsolete. 



Flowers erect or slightly declined, the segments narrow and spreading or recurved. 

 Filaments thickened at the base with no scales between them, prominently pro- 

 truded. Leaves strap-shaped. 



= = Perianth tube evident, often long. 

 - || Scape 1-flowered. 



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. 



J P Scape more than I -flowered (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. ORINUM. Perianth with a long slender straight or curved tube and 6 mostly long and 



narrow spreading or recurved divisions. Stamens long. Scape solid, bearing few 

 or many sessile or short-pediceled flowers, in an umbel. Bulb often columnar and 

 rising as if into a sort of stem. Leaves in several ranks. 



10. AMARYLLIS. Perianth various ; the divisions oblong or lanceolate, and the tube 



ribbed, short and declined. Flowers large and fragrant, umbellate and pediceled. 

 Scape solid. Leaves mostly 2-ranked. 



11. VALLOTA. Flowers large and showy, short-pediceled and umbellate. Perianth widely 



flaring above, the tube short and straight, the segments oblong-ovate and connected 

 at the base by a small callus. Involucral bracts 2 or 3. Style declined. Scape strong 

 and hollow.
