312 MONOCOTYLEDONES. 



herbs with bulbs ; the inflorescence is terminal. In many species repro- 

 duction takes place by means of bulbils (small bulbs) formed in the axils of 

 the foliage-leaves (e.g. Lilium bulbiferum, Jancifolium, etc., Gagea lancij'olia, 

 etc.), or in the bracts of the inflorescence (many species of Alliuni) ; in many 

 species several buds are developed as bulbs in the axils of the bulb-scales them- 

 selves (accessory buds arising close together), and in some the formation of 

 buds is common on the leaves. 



A. TULIPE.E, 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. HYACINTHEJE, 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; A gr aphis; Hyacinthus; PuscTikinia ; CMonodoxa; Muscari; 

 VeWieimia ; Urginea. 



C. ALLIED, ONION GROUP. Generally bulbs. Leaves radical. 

 Stem leafless with a compound umbellate or capitate inflorescence 

 of uni pared helicoid cymes, which before flowering are sur- 

 rounded by two broad involucral leaves. Allium. Filaments often 

 petaloid and bidentate ; in many species bulbils are found in the inflorescence. 

 Some species have flat leaves : A. sativum, Garlic ; A. porrum, Leek ; A. 

 ursinum; others have round, hollow leaves: A. cepa, Onion; A. jistulosum, 

 Winter Onion ; A. ascalonicum, Eschalot ; A. schcenoprasum, Chive. Gagea ; 

 honey is secreted at the base of the perianth, no special nectary; 

 inflorescence few-flowered AgapantJius ; Triteleia. 



D. ANTHERICE^E. Khizome; raceme; the leaves not fleshy and thick. 

 AntJtericum ; Asphodclus ; Bulbine ; Cldorophytum ; Bowiea has an almost leaf- 

 less stem frith curved, climbing branches. 



E. ALOINEJE, ALOES. Stem generally aerial and tree-like, bearing on its sum- 

 mit thick, fleshy leaves, often with a thorny edge (Fig. 306). Eaceme branched 

 or unbranched. Aloe ; Gaateria ; Yucca (has secondary thickening, p. 274). 



F. HEMEROCALLIDE^E. Phormium, (Ph. tenax. New Zealand Flax) ; Funckia 

 (Hosta') ; Hemcrocallis. 



At this point the following are best placed : Aphyllanthes (A. monspeliensis) ; 

 Xanthorrhcca (Black-boy) ; Xerotes ; Lomandra ; Kingia ; the very membranous, 

 dry perianth of the last resembles that of the Juncacea*, and also there are only 

 1-few ovules in the loculi.
