PoLyGonatum, Flowers white or greenish, cylindric, 6-lobed at 
the summit, on mostly naked pedicels in axillary pedunculate 
fascicles (sometimes solitary). Stamens on the tube; anthers 
linear-oblong, versatile. Style slender, deciduous; stigma ob- 
securely 3-lobed. Ovules 1 to3 pairs in each cell. Berry blue or 
black ; cells 1-2-seeded. Stem erect or curved; leaves sessile or 
nearly so; bracts caducous, minute. 
* * Perianth-segments distinct, small, spreading, persistent. 
19. Smrtacina. Flowers white, trimerous, solitary (in our species), 
20. 
with minute scarious bracts, in a racemose panicle or simple ra- 
ceme on an erect leafy stem. Stamens at the base; filaments 
subulate; anthers short-oblong, versatile. Style short, thick, per- 
sistent; stigma 38-lobed. Ovules a pair in each cell. Berry 
red or blue-black, 1—-3-seeded. Leaves mostly sessile. 
MatantHemMum. Flowers white, dimerous, solitary or fascicled, 
in a simple raceme upon a low 2—3-leaved stem. Filaments fili- 
form. Berry red. Leaves ovate- to lanceolate-cordate, mostly 
petiolate. Otherwise as Smilacina. 
Trise VII. Nolinez. Flowers very small, whitish, polygamo-dicecious, 
on short jointed solitary or fascicled pedicels, in a simple or compound panicle 
on a leafy stem from a thick woody caudex or rootstock: perianth campanu- 
late ; segments l-nerved: anthers ovate-cordate, versatile : stigmas very short, 
distinct, sessile or on a short style: ovules 6, in pairs at the base of the ovary : 
fruit dry and thin, indehiscent or bursting irregularly, 1-3-celled, 1-3-seeded : 
seed 
subglobose, with thin light-colored testa: leaves numerous, crowded, 
narrowly linear, elongated, rigid, striate, with rough or armed margins.

Norra. Flowers polygamo-diccious in a loosely racemose 
simple or compound panicle; segments oblong-ovate, usually 
acutish. Stamens included. Stigmas sessile or nearly so. Fruit 
rounded, deeply triquetrous, thin-membranous, 3-celled, 1-3- 
seeded, bursting irregularly. Seeds ovate to globose. Leaves 
unarmed. Naked caudex slender with a dilated base, or very 
short or wanting. Fertile flowers mostly solitary and on longer 
pedicels than the staminate. 
DasyLirion. Flowers dicecious in dense racemes forming a nar- 
row compound panicle, the tall leafy flowering stem terminating 
a stout naked cylindrical caudex. Perianth-segments oblongs 
obovate, obtuse. Stamens exserted. Style short. Fruit trian- 
gular and 3-winged, 1-celled, 1-seeded, coriaceous and indehiscent. 
Seed obtusely triangular. Leaves usually armed with hooked 
spines. Staminate flowers nearly sessile.
