[Illustration: FIG. 305.--_Colchicum autumnale. A_ Corm seen from the front: _k_ corm; _s′ s″_ scale-leaves embracing the flower-stalk; _wh_ base of flower-stalk with roots (_w_). _B_ Longitudinal section of corm and flower-stalk: _hh_ brown membrane surrounding the underground portion of the plant; _st_ flower-and leaf-stalk of previous year, the swollen basal portion forming the reservoir of reserve material. The new plant is a lateral shoot from the base of the corm (_k_) and has the following parts: the base bearing the roots (_w_), the central part (_k’_) which becomes the corm in the next year, the axis bearing the scale-leaves (_s’, s″_), the foliage-leaves (_l, l′″_), and the flowers (_b, b’_) which are borne in the axils of the uppermost foliage-leaves.] Order 2. =Liliaceæ (Lilies).= Flowers as in the Colchicaceæ but with _introrse_ anthers; _ovary free, 3-locular, with single style; capsule_ 3-locular with _loculicidal_ dehiscence.--The majority are herbs with _bulbs_; the inflorescence is _terminal_. In many species reproduction takes place by means of bulbils (small bulbs) formed in the axils of the foliage-leaves (_e.g. Lilium bulbiferum_, _lancifolium_, etc., _Gagea lancifolia_, etc.), or in the bracts of the inflorescence (many species of _Allium_); in many species several buds are developed as bulbs in the axils of the bulb-scales themselves (accessory buds arising close together), and in some the formation of buds is common on the leaves. =A.= TULIPEÆ, TULIP GROUP. Bulbs. The aerial, elongated stem bears the foliage-leaves. Flowers few but generally large, with free perianth-leaves. _Tulipa_; style absent, no honey; flowers generally solitary, erect.--_Fritillaria_ perianth campanulate with a round or oblong nectary at the base of each perianth-leaf.--_Lilium_; perianth widely open, generally turned back with a covered nectary-groove in the centre of each segment. Anthers versatile.--_Lloydia; Erythronium._ =B.= HYACINTHEÆ, HYACINTH GROUP. Bulbs. Leaves radical; aerial stem leafless with raceme or spike. In some the perianth-segments are free, in others united. Honey is produced often in glands or in the septa of the ovary (septal glands).--_Ornithogalum_ has a leafy stem; _Scilla_; _Eucomis_ has a tuft of floral-leaves above the raceme; _Agraphis_; _Hyacinthus_; _Puschkinia_; _Chionodoxa_; _Muscari_; _Veltheimia_; _Urginea_.
