2-celled anthers, and fruit a few to many-seeded pod or berry. 
I. Shrubby or rarely herbaceous, climbing or supported by a pair of tendrils of 
the ribbed and net-veined leaves: small diacious flowers in axillary umbels, with 
a deciduous perianth and apparently 1l-celled anthers. —SMILACE#, 
1. Smilax. Stigmas 3, sessile: fruit a berry, with 1 or 2 pendulous seeds in each 
cell. 
II. Never climbing by tendrils: very rarely diccious. 
A. Floral bracts scarions: stamens perigynous on the withering-persistent nerved 
perianth; anthers introrse: style undivided: fruit a loculicidal pod or berry: leaves 
transversely veined. 
* Flowers umbellate, with a scape from a coated corm or bulb; segments 1-nerved 
(except No. 5): pedicels not jointed. 
2. Allium. Perianth parted: pod deeply lobed (often crested); cells 1 or 2 seeded : 
alliaccous. 
3. Nottoscordum. Perianth parted: cells of pod several-seeded: not alliaceous. 
4. Androstephium. Perianth tubular funnelform, pale lilac: filaments united 
into a crown. 
5. Milla. Perianth salverform, greenish-white: stamens subsessile. 
*Flowers racemose or paniculate, on jointed pedicels: stems not from a bulb 
(except No. 6). 
+ Perianth-segments many-nerved: fruit a pod (except part of No. 10). 
++Leaves not thick: anthers not sagittate. 
6. Camassia. Flowers on pedicels jointed near the summit, bluish, slightly gib- 
boug, rather large: from a bulb. 
7. Anthericum. [Pedicels (usually fascicled) jointed near the middle: from a 
fleshy fibrous root. 
&. Scheenolirion. Pedicels (mostly solitary) jointed near the summit: from a 
thick rootstock. 
++ ++ Leaves thick: anthers sagittate. 
9, Hesperaloe. Flowers narrow-cylindric, reddish: style filiform, deciduous. 
10. Yucca. Flowers campanulate, white or whitish: style stout and persistent 
(or none).

11. Nolina. Flowers polygaimo-ditcious, in loose racemes: stamens included: 
fruit thin, 1 to 3-seeded. 
12. Dasylirion. Flowers dimcious, in dense racemes: stamens exserted: fruit 
coriaceous, 1-celled, 1-seeded. 
++ ++ Fruit a berry: leaves cordate to lanceolate. 
13, Polygonatum, Tlowers axillary, gamophyllous. 
14. Unifolium, Flowers in a terminal raceme, parted. 
B. Flora) bracts none or foliaceous: stamens hypogynous or at the base of the 
distinct segments of the deciduous perianth (except No 18); anthers more or less 
extrorse: style undivided, deciduous (stigma sessile aud persistent in Nos. 17 and 
18): fruit a loculicidal pod or berry: veinlets anastomosing (except Nos, 17 and 18), 
* i ruit a pod.
