TriBE I—MELANTHIOIDEAE. Buncu FLOWER TRIBE 
Herbs springing from a rootstock or less frequently from a bulb. Leaves 
all from the root or arising from the stem. Perianth of 6 equal parts, 
separate or slightly connected at the base. Flowers generally in length- 
ened clusters (spikes, racemes, panicles, I, II, III, p. 36, Part I), in 
Uvularia solitary. Ovary superior to the stamens and perianth and free 
from both. Stamens 6, inserted, not directly on the receptacle, but at the 
base of the segments of the perianth. Styles 3, sometimes quite short, 
the 3 divisions of the ovary closely connected, but not completely united 
as they are in the Lily and other flowers of the Lily family. The di- 
visions are, however, always free at the summit. Fruit a 3-parted cap- 
sule, splitting longitudinally through the partitions. 
Flowers in more or less elongated clusters.
