Answer 1

Answer:

Characters of Liliaceae:

Herbs rarely shrubs, stem underground rhizome, corm or bulb; leaves alternate, flowers actinomorphic, trimerous, hypogynous, perianth 6 in two whorls of 3 each, free or fused; stamen 3+3, epiphyllous, antiphyllous; gynoecium tricarpellary, syncarpous, ovary superior, axile placentation, two to many ovules per loculus; fruit capsule or berry; seed endospermic.

Habit:

Mostly herbs (Asphodelus), perennating by rhizome (Aloe), bulb (Lilium, Tulipa, Allium), tree (Dracena), climber (Asparagus, Smilax), xerophytic plants like Yucca, Aloe; cladodes in Asparagus and Ruscus.

Stem:

Herbaceous, or woody, solid or fistular, underground; aerial climbing or erect; underground stem may be corm, bulb or rhizome. In Ruscus and Asparagus aerial stems bear phylloclades (modified leaf-like branches), corm (Colchicum); secondary growth in Yucca. Dracaena, Aloe.

Leaves:

Alternate, opposite or whorled, radical and cauline, exstipulate, sessile or petiolate, sheathing leaf base; shape is variable scale-like (Asparagus), thick succulent and mucilaginous in Aloe, broad in Phormium tenax. In Smilax stipulate and stipules are modified into tendrils. Venation is usually parallel but reticulate in Smilax and Trillium.

Root:

Fibrous adventitious, sometimes tuberous (Asparagus).
